  SKF bearings distributor in China editing, along with the development of wind turbines, wind power generators become the development trend of the market, and one of its main components bearing various suppliers also become the target relative to catch up. SKF Group in order to meet this goal developed for wind turbine SKF Nautilus bearing tapered roller bearings.
 SKF specially developed for high-power wind turbines large contact angle of tapered roller bearings Nautilus bearings. SKF Nautilus bearing for the back to back in the form of tapered roller bearings, with the larger the contact angle (45 °). SKF Nautilus bearing not only allow single bearing spindle configurations as possible, while greatly reducing the traditional design of the drive chain length so compact wind turbine designs. Of course, this design also ensures the Cylindrical roller bearing or drive all the features.
SKF Nautilus bearing a remarkable feature is its use of a segmented plastic cage, segmented cage design, as each individual component is very small, and no intermediate links, even in the loaded state of the bearing will not affect the deformation of the shape of the cage and the rolling element guide. Also, because each component only four rolling, therefore, the holder will be generated by the friction is reduced to a minimum range. SKF Nautilus bearings of plastic, not only to ensure adequate strength, and its lighter weight to ensure the rotation of the bearing performance, while reducing the friction in the bearing, so that the application of more reliable and lubricating higher selectivity.
 In addition, the traditional pairing (or double row) tapered roller bearings, the contact angle is generally only about 20 °, while ensuring its larger radial load capability, backing bearings axial load carrying capacity and the ability to withstand the overturning moment subject to certain restrictions. SKF Bearing break through the traditional design of the contact angle, the contact angle of each single bearing enlarged to 45 °, in the bearing radial load capacity of the premise, greatly strengthened the axial load bearing capacity, while, SKF Bearings can also withstand large overturning moment. Configuration of the conventional double bearing comparison, SKF Nautilus bearing load is applied to two lines of intersection of the center line from the axis is much longer than the general configuration of tapered roller bearings, these two points of intersection on a point of the support shaft runs. But also to adjust the bearing preload condition to optimize the rigidity of the system.

Analyze foreign wind power industry wind power bearing prospects
With the wind Cylindrical roller bearing popular, and made ​​a lot of contribution to environmental protection, energy could reduce oil dependence, we can see the wind power industry prospects are good prospects, whether developed or developing countries, the countries have issued a series of policies , in as much as possible to make every effort for the environment.
Recently in the United States, President Barack Obama urged Congress to extend the field of wind power tax breaks validity.
Obama's a factory TPI speech that "if Congress does not act, then companies such as TPI would be a great impact on the unemployment rate will be further enhanced. This is not conjecture, this is the fact that iron clank . "TPI is a global fan blades supplier.
In 2004, the United States formally introduced tax breaks. If Congress does not extend its validity, then the end of this year will lapse. Under the policy, the electricity through wind power generation in the first decade can enjoy 2.2 cents per kilowatt-hour tax credit.
He said that since taking office, the new domestic energy demand has doubled, including solar, wind, etc. Countries need energy independence, which the people's income, environmental protection and national security is beneficial.
"As we improve the local energy dependence, reduce oil imports, for the people to create more employment opportunities, which is the best outcome."
American Wind Energy Association, said that the United States currently has nearly 500 production plants, a total of 30,000 employees struggle in the wind energy supply chain, they expect incentives to continue.

2012 development trend of China's bearing industry, what is?

Expected in 2012 will have bearing export growth of about 15%, reaching $ 5.2 billion。

Since thrust tapered roller bearing production is less

Thrust tapered roller bearing structure, performance characteristics
Since thrust tapered roller bearings rolling body is tapered roller, rolling in the structure of the bus and the raceway washers are bus lines intersect at a point in the axis of the bearing, which can form pure rolling rolling surface, speed limit higher thrust cylindrical roller bearings.
Thrust tapered roller bearings can withstand a one-way axial load. Thrust tapered roller bearing type code 90000.
Since thrust tapered roller bearing production is less, the plant has produced models are mostly nonstandard dimensions, while the standard dimensions of the series, varieties produce less, and therefore these bearings is currently no national standards promulgated dimensionsScrew-down bearings - Thrust Tapered Roller Cylindrical roller bearing
Third, this type of thrust tapered roller bearings must be able to withstand enormous axial load, and allows the threaded shaft angular displacement relative to the support. Therefore, these bearings usually full roller type, with large diameter and long rollers. In order to withstand the roll offset in the bearing housing on the bearing not adversely affect the performance of this bearing has a spherical seat. The seat can be a shaft or bearing seat box seat.
In the spherical shaft seat and the corresponding concave spherical threaded shaft or pressure roller between the baffle set above a spherical seat of the bearing axis, will produce the necessary right of offset. LYTBZ can also supply the pressure plate.
Spherical bearing box seat when the offset from the bearing housing on the seat between the baffle and the pressure roller groups to bear. This bearing pressure plate is usually supplied with the same bearing.
LYTBZ produce a variety of designs screw bearings; This bearing is customized to meet the special requirements of a particular application

Competitiveness of the domestic steel ball situation and development trend analysis
