Roller Follower Full Complement Cylindrical Crowned Outer Ring (NUTR)

NUTR, track roller, yoke type, crowned outer diameter with inner ring and washers (two paths of cylindrical rollers).

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.
