Product Details

Needle roller bearings with thrust roller bearings are also designed for thrust loads, but feature higher axial load ratings than versions using thrust ball bearings.

●Minimal elastic deformation of rolling contact surfaces under load.

●High rotational accuracy for both horizontal and vertical shafts achieved by precisely finished thrust bearings.

●Optional dust cover prevents grease leakage and dirt penetration in demanding environments. Dust cover is made of a thin steel plate and fixed to a groove on the outer ring collar.

●Optional inner ring bearing style available.
