Thrust Cylindrical Roller Bearings, GS-shaped bearing ring
Brand :
NTN
Caution
Product Description
[Features]
·The bearing combines rollers, a disk-shaped bearing ring, and a thrust retainer in which needle-shaped or cylindrical rollers are installed radially, and bears an unidirectional axial load.
·A shaft and housing can also be used directly as a raceway without a bearing ring, which enables low-profile, lightweight and compact design structures.
·This type of thrust roller bearing is not capable of performing a theoretically perfect rolling motion and will experience slippage on the raceway surface; however, in most cases, it does not hinder practical use and can rotate at a relatively high speed.
