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.

McGill® CAMROL® 2240110000 CF Series Cylindrical OD Cam Follower With LUBRI-DISC® Seal, 2-1/2 in Dia x 1-1/2 in W Roller, 1 in Dia x 2-1/4 in L Stud, Chrome Steel Roller
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.
