Roller followers

Roller followers are bearings designed for outer ring rotation, in which needle rollers are incorporated in a thick-walled outer ring. Both crowned and cylindrical outer rings are available.

 

In roller followers, there are two types of bearing available, the caged type and the full complement type. The caged type is useful for applications at high-speed rotation. The full complement type is suitable for heavy-load applications at low-speed rotation or oscillating motions.

 

Roller followers are produced in open type, shield type and sealed type. In the sealed type, special synthetic rubber seals are assembled, which are effective in preventing dust and dirt penetration.

The outer rings run directly on mating track surfaces.

 

These bearings are available in a variety of types to suit almost any kind of application. They are widely used for cam mechanisms and for the linear motion of conveying equipment.
