Cam follower bearings are a specialized roller bearing or needle bearing designed to follow cams or tracks in a wide range of motion systems. As a type of anti-friction needle bearing, their construction consists of a heavier outer ring that includes needle rollers, which allow for cam followers to work smoothly in a given application. The bearings are also sealed to help prevent contamination and retain lubrication. Cam follower bearings offer high dynamic and static load carrying capabilities in a compact design.
