Cam Followers (Yoke and Stud Type)

Cam Followers are designed to run directly on surfaces such as cams, ramps, and slideways. They are commonly used as track rollers, cam followers, and in a wide range of linear motion systems. To meet the demands of heavy radial loads, often accompanied by repeated shocks, NIBL cam followers feature a heavy-section outer ring made of high-strength steel, hardened to 58–62 HR. The outer ring includes a lubrication groove, which prevents impurities from entering the bearing and protects against scaling and galling of the bearing track.

The convex (crowned) outer ring is designed to tolerate misalignment of contact surfaces. Crowned outer rings are ideal when the cam follower’s axis is not parallel to the track surface or is skewed relative to the direction of travel. These rings support high radial loads and reduce edge stresses caused by misalignment. Crowned outer rings are especially suited for applications with curved or circular tracks. NIBL offers cam followers with a crowned outer ring as a standard feature, while cam followers with a cylindrical outer ring are also available (suffix X). For using cam followers with crowned outer rings as bearings, please consult NIBL.

Cam followers with a full complement of needles offer maximum dynamic and static load-carrying capacity and anti-friction performance in a compact design. Cage-guided cam followers provide ample space for grease, making them ideal for applications where re-lubrication is infrequent, allowing for high-speed operation. Sealed cam followers require low maintenance, with an operating temperature range limited by the grease and seal material to between -30°C and +100°C.

NIBL stud-type cam followers consist of a solid stud with high tensile strength, featuring an integral rib on one side, a thick-walled outer ring, a rolling element set, and a thrust washer pressed onto the other side of the stud. These components form an integrated unit, with the areas serving as the raceway for the rolling elements and the abutment surfaces hardened for durability.
