NSK Bearings through the "MOTION & CONTROL" (operation and control) technology, in order to build a comfortable and safe community dedication. While safeguarding the global environment, we should strengthen our solidarity and cooperation among nations, people and people through undertakings in the world.
Japan's Seiko Co., Ltd. (NSKLTD) was established in 1916, Japan is the country's first design and production of bearings manufacturers. For decades, NSK has developed countless new bearings to meet the needs of users all over the world, and has made great contributions to industrial development and technological progress. At the same time NSK relies on its technical advantages in precision machining to continuously develop high, refined and advanced products such as auto parts and precision mechanical components and actively carry out diversified operations in the field of electronic applications.
Gradually establish and perfect the trinity business system with production as the core, technology as guidance and marketing information as an aid. NSK will speed up the localization of this system so as to provide more direct and complete services for the vast number of users in China. China's industrial modernization make its due contribution.
NSK thrust roller bearings for axial load to bear the main axis, the radial joint load, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this bearing friction coefficient is lower, higher speed, and with self-aligning performance.
For the axial load-bearing shaft, the radial joint load, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this bearing friction coefficient is lower, higher speed, and with self-aligning performance.
29000-type bearings for the non-symmetrical spherical roller spherical roller, roller and raceway can reduce the relative sliding in the work, and long roller, large diameter, the number of large rollers, high load capacity, usually with oil lubrication, Individual low-speed grease lubrication available. In the design selection, should be preferred;
80000-type thrust cylindrical roller bearings , 90000-type thrust tapered roller bearings and AXK-type thrust needle roller bearings can withstand one-way axial load than thrust ball bearings it is much larger axial load capacity and rigidity, Take up small axial space.
Thrust cylindrical roller bearings and thrust tapered roller bearings for low speed applications, thrust tapered roller bearings slightly higher than the speed of thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings, can only withstand one-way axial load and slight impact, can limit the shaft (or housing) in one direction of axial displacement, it can be used as a one-way axial positioning. But its carrying capacity is far greater than the thrust ball bearings. Roller rolling, due to the different speeds at both ends of the roller so that the roller in the raceway inevitably slip, so the limit speed of these bearings than the thrust ball bearings, usually only suitable for low-speed operation occasions.
Standard design thrust cylindrical roller bearings made of metal body cage , according to user requirements, but also can use other types or materials of the cage. Thrust tapered roller bearings can only withstand one-way axial load, can limit the axial displacement of the bearing one-way, it can be used as a one-way axial positioning. Compared with the thrust cylindrical roller bearings, carrying capacity, the relative sliding small, but the lower limit speed.
