BELTOP 8 ball bearings are high-reliability and low-friction bearing. And people specially developed it for belt-type continuously variable transmissions (CVT), which helps to improve the reliability and efficiency of CVT. Therefore, the belt-type continuously variable transmission transmits engine power through belts and pulleys and has continuous step-less speed regulation capability.
The performance of the BELTOP 8 bearing is as follows:
Extend the life expectancy by optimizing internal technical parameters and using UE/HTF in the ferrule. In addition, apply the EQTF to the ball, and use the plastic cage instead of the conventional cage to suppress the deterioration of the surface roughness of the ball during the operation of the bearing. So it can extend the service life. In addition, by using the anti-creep technology that increases the rigidity of the outer ring and the addition of a solid lubricating coating. Furthermore, it is possible to suppress an increase in CVT vibration caused by the wear of the bearing housing.
On one hand, the plastic bearing cage reduces the frictional resistance of the lubricant generated by the bearing rotation. On the other hand, it reduces friction.
Long-life technology (UR, THE, and EQTF) is applied by optimizing internal technical parameters, and the size and weight can be reduced by using a biased channel and a shoulder trim to suppress stray abrasion.
BELTOP 8's all features are not only suitable for belt-type continuously variable transmissions, but also for various transmissions, including automatic transmissions and electric vehicles/hybrids. Automotive Transmission. On the other words, NSK's BEL TOP 8 product includes projects based on basic technology, experience, and achievements. Because it is high reliability, low torque, small size and lightweight for a belt-type continuously variable transmission that can have applications in harsh environments. Therefore, rolling bearings have currently usages in many belts CVTs.
