About Track Roller

Track rollers (also known as cam followers) are characterized by their thick-walled outer rings that run directly on a track.
The thick outer rings permit high load-carrying capability while minimizing both distortion and bending stresses.
Sealed designs with internal thrust washers help extend service life under conditions of infrequent lubrication.

Features

Available in two basic designs: with an inner ring for straddle mounting in a yoke or with an integral stud for cantilever mounting.

Benefits

High load-carrying capability with minimized distortion and bending stresses.
Extended service life under conditions of infrequent re-lubrication.
