Automotive Bearings Manufacturer

With the equipment, technology level of ascent, such as domestic enterprises and tianma wazhou import substitution has begun by yaw and change to the slurry bearing field spindle bearing and gear box bearing expansion. Wind power bearing market space, only the above bearing enormous market capacity of 2009 reaches 50 billion yuan of above, wind power bearing oligopoly competition pattern has been formed and is expected to fall modestly profitable space is relatively posture, barriers to entry, we also expect high spindle bearing &gearboxes lubricated by bearing, according to the calculation, wazhou B future three years are: $0.40 EPS was $0.50 0.65 yuan, and, among which the 2009 PE is only 10 times, giving wazhou B “immediately” investment rating, wind power generator maintain tianma shares “increasing” investment rating.

Domestic enterprises import substitution by yaw and change to high-end plasma bearing spindle bearing and gear box bearing expansion.

In wind power yaw and variable plasma bearing field, is expected to domestic enterprises wazhou group and tianma shares were up to 10 billion revenue 09, and amounted to wind generator of RMB dominant market share rate up to 80%, basically complete import substitution.

For spindle bearing spindle bearing and gear box, precision level up to equipment, material P4, selection and design level higher, on behalf of wind power bearing the highest level. But in this field, domestic wind turbines enterprises will come true import substitution, wazhou shares to realize the 2009 400 million RMB income, tianma shares also is expected to have gained ground in about three years between finish is expected to import substitution.

Wind power bearing market space is huge, and tianma infuriated only wazhou 2009 market capacity is bearing 50 million yuan of above.

According to the calculation, yaw and variable plasma bearing the 2009 market capacity up to 20 billion yuan of above, spindle bearing &gearboxes lubricated by bearing 30 billion yuan total also above, import substitution space is enormous.

Currently, the domestic wind power bearing gradually formed a large-scale, serial production, the main enterprises ZWZ, Los shaft, Research Technology, radius support, Shanghai United, and other related enterprises.

China Bearing Industry Association, according to staff revealed that wind generator of aut bearings, yaw bearings and pitch bearing relatively low technical threshold, while the growth rate of the spindle bearings and high-tech devices bearings, generator wheel  bearings essentially mature technology generic products. Currently, the domestic wind power bearing capacity of enterprises focused on changes in the yaw bearing and bearing on the pulp, and to 3 megawatts of wind power equipment for the main bearings for the spindle bearings and bearing accelerator, the basic dependent on imports, only the individual Initial involvement of domestic enterprises.

It is understood that the bearing industry in China Horizontal wind turbines bearing on the design, manufacturing and testing techniques are far from fully digested, such as the spindle bearing is what kind of bearings as well, which pitch is a structure bearing slewing ring as well, slewing bearing raceway hardened teeth and how to prevent cracks, how to ensure that the surface hardness and hardened layer depth is still at an exploratory research into difficulty.

Recently, ZWZ learned from Dalian, but also supporting a number of major equipment for the country’s high-end bearing products successfully produced here, to fill the gap: 5 MW wind turbine pitch bearing sent to the user installed; completion of the main shield bearings and bearings and other R & D hob and start vibrating screen installed test; large portfolio backing, precision, sealed bearings successfully developed, through the user’s acceptance of … …

At the same time, a total investment of 500 million yuan Shanghai Electric’s wind power turbines bearing large clean and efficient production line technological transformation project completion and operation of the first units of 3.6 MW offshore wind power bearing off the assembly line. Shanghai Electric from the introduction of technology to the joint design, and then to independent development, out of the bearing on the development of a new road. At present, China’s technological development capability and home  wind generator technical personnel, process control have reached the international level, the cost of imported bearings only about 2 / 3, after mass production is expected to drop to import bearings 1 / 2.

While filling the gaps in a day, but domestic companies focused their attention on the global trend, the progressive realization of high-end products bearing the efforts of industrial upgrading, will change many of our key focus areas of technology and equipment on high-precision, high reliability, high speed bearing long-term dependence import condition.

China’s bearing industry in 2010, sales revenue and profit growth surpassed the three into, and profit growth than revenue growth. The rapid development of bearing industry, but also key areas of our country independent of the major technologies and equipment have made outstanding contributions. However, the Secretary-General Wang Quanqing China Bearing Industry Association, told the author admits, the pace of development in China is still bearing the high-end host can not keep up the pace of development.
I learned that in high-speed railway in China wind power bearing spindle bearings, bearing accelerator is still a wide gap between the fields. Among them, the speed of more than 160 km EMU used in bearings, SKF from Sweden is still full at the imports and other international giants.
I recently learned from the China Bearing Industry Association, China’s bearing industry in 2010 achieved rapid development, the end of 2010, bearing well-run industry production, economic efficiency has improved exports rebounded sharply, imports still on
It is worth mentioning that China Wheel Bearing Industry Association, organized in 2010, a large aircraft, high-iron bearings and bearing joint research, and has achieved initial results. Bearing industry optimistic to expect that research in accordance with the current development speed, and if all goes well, the next two or three years, Chinese-made high-speed railway will be able to truly support bearings.
Revenue 突 mark
Although the final statistics have not yet released, but preliminary data show that the bearing industry in 2010 will be  main business revenue mark, reaching 120 billion yuan, the growth rate will reach 30%. In the automotive, agricultural machinery, household appliances industry driven, increased demand for small bearings in 2010, predicted that the annual bearing production will reach 150 million units, an increase of 36.36%. Expected total profit of 6.5 billion, an increase of 38.3%.
Bearing in 2010 will reach 4.15 billion units exported, up, long reach 53.65%, compared with 28.9% growth in 2008; export volume will reach 3.32 billion U.S. dollars, an increase of about 63.6%, compared with 11.4% growth in 2008.
Wang Quanqing analysis, export growth was mainly due to the development of China’s Clutch Release Bearings industry over recent years, products bearing the micro level of technical quality is close to international standard, miniature bearings in the world market, has occupied a stable market.
Bearing imports in 2010 will reach 18 million units, up 30%, compared with 13.7% growth in 2008. Use of foreign exchange of imports will reach 3.8 billion, an increase of 34.38%, compared with 41.8% growth in 2008 or so. Import deficit may reach $ 480,000,000.
“Internal injuries” troubled industry
However, bearing problems in development of the industry can not be ignored.
As China’s emerging strategic industries (such as high-speed railway, large aircraft) and high-end equipment manufacturing (such as some high-speed precision machine tools) the development of high-end bearings imports growing rapidly. Currently all imports of high-speed rail for wind generator bearings, part of the high-speed precision machine tool bearings need to be imported. In the long run, on the growth of China’s emerging strategic industries will be adversely affected.
Not keep pace with the development of high-end part of the host bearing the pace of development. First, instability due to raw material properties, resulting in bearing life and reliability of the instability, it is difficult to enter the host market; second is due to the rapid development of high-end domestic wind turbines equipment, all kinds of high-end bench test equipment, bearings and other modern inputs too large experimental methods not kept pace, resulting in bearing R & D progress has been slower. Basic components as a high-speed train rail bearing areas, the Swedish SKF, German FAG, NTN Japan and other international giants still firmly occupy the Chinese market.

A local company whose corporate parent is located in Japan is reporting that despite last week’s massive earthquake and tsunami that hit the northeast part of that island nation, operations have experienced little disruption.

A manufacturer of rod end and spherical auto bearings for the aerospace industry, Laconia-based New Hampshire Ball Bearing’s Astro Division is a subsidiary of Minebea, a multinational company based in Tokyo. Minebea has several manufacturing facilities in Japan, some near the area where the earthquake and tsunami struck on March 11.

As of Monday morning, “we know that there was absolutely no significant damage to any of our larger factories” in Nagano, Shizuoka, Kanagawa, Tottori and Gunma wind turbines generators prefectures and Metropolitan Tokyo, said Gary Groleau, who is the senior division manager of Astro Division. He added that the Minebea headquarters were not affected but that planned, rolling electrical blackouts would likely have an impact on some smaller facilities in the Kanto region.

On the company’s website, Minebea expressed “its heartfelt sympathy” for all those affected by the Tohoku earthquake.

The statement explained that production activities Japan “will not be affected significantly by this earthquake for the short term as Minebea produces more than 90 percent of products such as homemade wind generator outside of Japan, such as in Thailand and China. We will carefully watch future developments and situations.”

“All of our employees are safe and sound” at Astro Division, said Groleau, although one executive who was flying back to Japan after being in New Hampshire — NHBB has plants in Laconia and Peterborough — had his flight diverted temporarily to Anchorage, AK before being able to continue on and join a second group of colleagues in Tokyo.

Also receiving good news this week from Japan was Bryon Middlekauff, a professor of geography at Plymouth State University, who has stayed in touch with a wind generators manufacturers former student who lives there.

After initially receiving a frantic text mail from the student, replying, and then hearing nothing for several days, Middlekauff sent The Citizen an e-mail announcing the all-clear.

I  it is reported, 2010 bearing export will reach to 41.5 million sets, will amount to 53.65% year-on-year growth than 2008 28.9%,; Export will reach $33.2 billion, an increase of about 63.6% than 2008 growth by 11.4 per cent.

association personage expresses, mainly because of wind turbines manufacturers a sharp increase in exports in recent years, through bearing industry, small small-sized bearing product technical quality level is already close to international level, in global small small-sized bearing market already occupied stable market.

according to introducing, at present, including a listed company, the local enterprises most production is small and small and medium-sized bearing, large and medium-sized bearing than the yield of less than 3%.

car driven bearing countryside sales

in January 2011, shaft grind technology confirmed that China bearing industry association has identified as lead by the company in bearing industry unit that, in the research of high speed railway bearings. Association sources, and organization and promote the development of high iron for windmill generator bearings work in 2011 will be one of centers association.

although final statistics released, but not the data shows, bearing industry 2010 advocate business wu income would exceed RMB 100 billion mark, reach 120 billion yuan, growth will reach 30%

in car, farm, household electrical appliance industry, 2010 the pull small small-sized bearing demand is expected to soar, annual bearing output will reach 150 million sets, year-on-year growth). Can be expected to achieve total profit 65 billion yuan, a year-on-year growth 38.3%.

high iron market will into industry development direction

according to the long-term rail network home wind turbines planning (2008) “, to adjust in 2012 will be built the high speed rail passenger special line, 42, total mileage will more than 1.3 million kilometers; China 2020 high-speed railway mileage will reach to 1.8 million kilometers.

association personage thinks, 2011, automobile, farm machinery, electrical home appliances, the volatility of the market for bearing industry will impact the development speed of the RMB exchange rate, at the same time, along with the rise in ordinary bearing and the competitiveness of the bearings will further for wind generators weakened, therefore, 2011 will be bearing industry growth slowdown.

but will see more long-term time span, high in iron industry drive, the development prospects of bearing industry is very considerable.

the personage inside course of study thinks, according to the present working speed, if all goes well, the future of two or three years, domestic high speed bearings is expected to form a complete set. And the 2010 close to a quarter of its achievements in China’s bearing industry association fow wind power generator for bearing industry for 2011 growth performance drop.

hongyuan securities analysts XunJian think over the next three years, which means that our high iron bearing market will more than 20 million yuan, the future of space is enormous import substitution.

Commercial DianCiZao guestroom items, security equipment, crane chassis parts, second-hand equipment transfer, hoisting hoisting equipment, intelligent household, stoves, car seat cushion, filling machinery, petroleum equipment, conference broadcast, bench box, etc. The industry, we often see bearing and import bearing applications, today we mainly the import bearings roller to transform for the detailed introduced. Roller rebuilding in normal import bearings in the flat, we often wiped car will meet to roller carding machine import bearings and inner sleeve embrace death or severe worn wait for a phenomenon.
Make feed roller of inner sleeve and import bearings (94.35) GengHuanLv high, average one, two cycle should be replaced.
According to the observation found in import bearings lock will have to keep frame for extrusion deformation, red-tipped mechanical action in strong next break or badly worn, inside set of tail the emergence of a convex platform, the surface has split the grinded groove.
Feed roller bearing and inner sleeve damage not only increases the flat car workers wiped labor intensity, also increased a machine material consumption.
Rui beautiful bearing company can wind turbine generator long-term supply by fax: 0755-33197003 0755-33197003: inner sleeve analysis thinks, produced in the wear convex platform is lead to feed roller bearings, holding in death the real cause of the damage.
During operation in machines, wear is inevitable, when inner sleeve to produce convex platform will import bearings maintains a seriously extruding make its damage, maintains a once damage will show disorder and red-tipped turning, very easy damage.
On the flat wipe car also found that inner sleeve convex platform for bearing remove creates an obstacle, to refuel difficult.
In view of the above situation, through trial and error, found changing bearing assembly location can solve these problems.
Particular way is: (1) first remove the feed Clutch Release Bearings terminals, cann cover front highlight department for turning processing, length depends, in about about 5mm; (2) in assembly bearing after good cover import bearings again, make its adhere to knock cover.
Then bearings and inner sleeve back-end flush parallel to the surface of red-tipped within the wear and red-tipped to bearing damage.
In the production practice, we also found that the reform could not only reduce the damage of bearing, and can increase the import bearings lubrication.
Because the position, and after bearing a loop slot wind generators face before giving in to import bearing oiling extra oil will flow when the grooves, right now, just became a storage tank trust in bearing drive to will continuity, thereby reducing the non-oil red-tipped wear.

Because of wind power bearings in short supply, for one year, dalian wafangdian bearing group precision technology and manufacturing industrial park staff night fighting in producing, batch market much-needed fan series bearing fruit, the first half of this year, rapid wazhou home wind-power generator for bearing year-Wind generator’s control on-year growth of the 220%.
Wazhou group from the 1990s started developing a wind-power  generator bearing, is the earliest engaged in research &development of wind power bearing. Along with the rapid development of wind power industry at home and abroad, especially wind power project was identified as the national key developing sixteen important technical special one, the company will mw wind generator bearing level of r&d as an important r&d project, and precision technology and manufacturing in wazhou industrial park in the establishment of a modern wind generator bearing production base. December 2008 national development and reform commission and reply the wazhou mw wind power equipment parts localization level expanding production capacity technical renovation programs, with the total investment of nearly 10 million yuan.
In the introduction of the contemporary world most advanced all finishing equipment, adopting advanced processing technology at the same time, the company investment to transform, technical center with xian jiaotong university, dalian university of technology such as key universities and research institutes appreciaties joint technology development and research, all-round raised the enterprise research and development ability and independent innovation level, and supporting built domestic bearing industry’s biggest bearing test center, formed the product research and development, wind turbines manufacturers technique, detection technology, three development platform.
In the development, fan bearing made from raw material, wazhou product design, manufacturing process to test etc. Several proprietary technology, formed the wind bearing special standard. Introduced in France, Germany, Sweden, Italy and other countries advanced equipment, has formed a wind change propeller bearing and yaw bearing, growth machine bearings, spindle bearing such production base. And in domestic wind turbines sole developed wind wheel bearings, growth machine bearing and spindle bearing large test enginery, fill a large domestic bearing test of blank, fully guarantee the each batch (minor) wind-driven generator bearing quality, bearing achieved the international similar product level, and for many domestic and world famous wind power supply enterprise batch.
So far, wazhou has formed yearly produces 6000 TaiFen wind-power change propeller and yaw bearing, annual output of 6,000 TaiFen growth machine bearings, annual output of 6,000 TaiFen of spindle bearing, annual output of 30,000 sets of generator bearing production scale. Supporting the product variety of 750 kw to 3 mw of various models, basic covers the nation and even the world all the fan of supporting products, become China currently the only house can all-around batch for wind power is supplied in supporting service enterprise.

Along with the development of new energy application, as the new energy sources development early wind, in power grid occupy a growing proportion. Meanwhile, more ball bearings manufacturers developed various wind generators host, in order to strengthen its products in the market competition strength, from transmission chain design improvement, to various parts different function of consideration, all become wind generators mainframe design improvement of different factors.

As the wind generators’ main components, Thrust Bearings manufacturer chooses is always host the most concern, whether bearing itself design, or bearing configuration choice, all depends on the performance of the wind generator host and service life.

Due to the wind generator operating conditions complex, host maintenance cost is higher, and ensure that the operation reliability of wind turbine generators, namely the using life and has been troubling mainframe manufacturers important issues. One bearing application to host the influence of efficiency is very important. Therefore, based on the complexity of the wind generator, SKF specifically for its and developed a special bearings, namely “Nautilus” bearings – with a special big contact Angle of double row circular cone roller bearings (figure 1).

Wind generators host bearing configuration

The traditional wind electric generator bearing configuration for the double bearing support. According to the working principle of wind turbine generators, transmission chain usually adopts below design: spindle, gear box (growth box) and generators. In the spindle, adopt double bearing configuration is more traditional and more common form, the bearing types according to the requirement of design varies, but usually the more traditional bearing configured for spherical roller bearing configuration or tapered roller bearings configuration.
Double bearing spindle bearing the benefit is the configuration of the most complex suffered wind load, except torque outside, basically do not have other load will transfer to the transmission chain of gear box, give a gearbox design caused great convenience. But this configuration also has its own shortcomings such as transmission chain longer, except spindle length outside, consider spindle and gearbox connection couplings. Length. Therefore, in small power of wind generators, this configuration more common. In high-power wind generators, long transmission chain means greater volume and higher manufacturing cost.

Now the latest spindle bearing configuration solution for single bearing support. Along with the development of wind turbine generators, high-power wind generators for market development tendency, high energy density also becomes various mainframe manufacturers grabbed pursued goals and offer bearing is designed to bring enormous challenges.

In high-power homebuilt wind generators to ensure adequate load capacity to withstand much wind load. Therefore, the size of the spindle, including bearings must increase, and this will cause the increase of host overall weight, which brings about the host related components, including tower component such as higher production costs. So whether there can improve Horizontal wind turbines power can also reduce weight and reduce the whole wind-driven generator manufacturing costs? This became mainframe manufacturers and components manufacturers in the face of increasingly urgent problem, because that means a decline in the cost of product competition ability enhancement. Based on the above various purpose, SKF specifically for high-power wind-driven generator developed big contact Angle of tapered roller bearings

Luoyang new strong united rotary bearing company for domestic one of famous wind generators enterprise developed 2MW direct driving type wind turbine generator spindle bearing recently success for several months, mintz, this company departments to coordinate with each other mutual cooperation, and overcome the difficulties in production process, finally successfully completed trial-production task.

The successful development of the spindle bearing marks the plant’s wind turbines for bearing r&d, manufacturing technology and at a much higher level, and will promote and speeds up the domestic substitution import bearing spindle bearing the pace.

Recently, Beijing economy and informatization commission, bureau of Beijing ouzhi bearing 2.5 megawatts above wind generator for auto bearing and super-large bearing production base project attach great importance, after carefully examine and verify, release documents will be listed in the project of Beijing industrial development fund projects, and measures to support them.

This project new requisition of land construction land 25700 square meters, the newly built Clutch Release Bearings r&d, manufacturing plant and equipment parts 18400 square meters, advanced equipment and testing equipment. New base has started early construction, is completed, it will further promote laser surface treatment technology in fan bearing and super-large bearing of the application, promote 2.5 megawatts above wind generator bearing the nationalization of the high power, which helps reduce wind turbine  generator manufacturers costs and save money, To the green environmental protection, energy conservation and emission reduction, To improve benefit form a good situation for sustainable development. At present, this project has a comprehensive construction implementation, ensure December 2011 months ago form production ability.
