Koyo YCRS-36 Inch Series Uncaged Yoke Type Needle Bearing Track Roller, 5/8 in Dia Bore, 2-1/4 in Dia x 1-1/4 in W Roller, 7800 lbf Dynamic/16500 lbf Static Load
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.

Needle Roller Cam Followers have a heavy outer ring cross section and a full complement of needle rollers. They offer high dynamic and static load carrying capability, and anti-friction performance, in a compact design. They are used as track rollers, cam followers, and in a wide range of linear motion systems.
The McGill® CAMROL® full complement needle bearings feature black oxide treated bearing steel. They are available in two basic mounting styles for use in mechanical automation or linear motion applications. Our basic features each contribute to superior performance. The LUBRIDISC® seal option helps prevent metal to metal contact within the bearing. It also provides a barrier for containment entry and blowout protection when relubricating. These bearings are available with several dimensional choices. The seal options and combinations provide a specific solution for each application. Within the following section you can learn more about these features and how they can be applied to your application.
