Crowned Outer Rings are used to minimize outer ring thrusting in applications 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. Crowned outer rings are a good selection for use with curved or circular tracks. In well aligned applications, crowned outer rings can cause accelerated track wear.

Cam Followers are presented in five groups: Needle Roller Cam Followers; Caged Roller Followers; RBC Roller®; Long Life Cam Followers; Material Handling Rollers and Sheaves; and Airframe Track Rollers and Needle Bearings. RBC also produces a wide range of custom designed cam followers and track rollers. Designers and users with unusual application requirements should contact RBC to discuss custom designed cam followers.
