Do you know Cam Follower Roller Type Bearing?

Cam follower roller type bearing is a roller or needle bearing that is specifically designed to follow cams or tracks.  As a follower bearing of cam mechanism and linear motion, it has high rigidity and precision, and is widely used in the guiding mechanism of exposure machine, winding machine and automatic equipment.

The outer ring of cam follower roller type bearing has spherical and cylindrical surfaces. Spherical outer ring bearing can reduce the uneven load caused by installation error. The cylindrical outer ring bearing has a large contact area with the relative sliding surface, which is suitable for the sliding surface with large load or low hardness.It can accommodate both symmetrical and elliptical motion rotation applications.There are many configurations of cam followers available, but they are commonly defined by how they mount to the mating part.

Cam follower roller type-Stud Type

There are two major cam follower bearing in use; stud type and yoke type.  In both types, a stem or shaft extends from the inner race.  The stem can be either hollow to press onto a stub shaft (yoke type) or incorporate threads to be screwed into a corresponding threaded hole (stud type).  Stud type cam bearings are typically a standard size but there are heavier studs available that can handle bigger static loads.

Cam follower roller type-Yoke Type

Yoke types can support the same sized static loads as heavy studs but are best suited for applications that require minimal deflection.

Applications

Cam follower roller type bearings are particularly useful in applications where the load can be supported by the head as a guide roller or when a specific pattern of travel is required.  Sufficient hardness is required in the components to reduce the wear due to rolling and sliding friction.
