Cam Follower Bearing

Cam followers are designed to run directly on surfaces such as cams, ramps, and slide ways. They are used as track rollers, cam followers, and in a wide range of linear motion systems. In order to meet the operating conditions of heavy radial loads usually accompanied by repeated shocks. NIBL cam followers have a heavy section outer ring of high strength steel hardened to 58 – 62 HR. There is a lubrication groove on the outer ring, which prevents the introduction of impurities into the bearing scaling and galling of the bearing track. The convex (crowned) outer ring tolerating out-of-parallelism of contact surfaces. Crowned outer rings are used where the axis of the cam follower is not parallel to the surface of the track or is skewed relative to the direction of travel. Outer ring with crowned outside surface supports high radial loads and reduces edge stresses which occur due to misalignment. Crowned outer rings are best suited in applications with curved or circular tracks. NIBL offers cam followers with a crowned outer ring as a standard feature.
