Caged roller followers can function immediately over a hardened and floor shaft (HRc 58 min, 16 rms min surface area finish) or can be utilized with matching internal rings. Functioning without an inner ring yields the most important feasible shaft diameter with best energy and rigidity.

Some suppliers include a back again plate that cuts down friction in between the bearing’s outer ring as well as respective finish plate or flange. The plate separates these adjacent faces, so steel-to-metallic sliding contact is eradicated.

This kind of cam uses spring pressure. Compression springs are preloaded into the follower to be certain contact with the area constantly.

Thrust disk cam followers element synthetic resin thrust washers with Excellent don and warmth resistance.

Cam Followers are developed with outer rings of enormous radial cross section to face up to large rolling and shock hundreds on course-form or cam-managed tools. The surface diameters on the outer rings are possibly profiled or cylindrical.
