Cam Follower Needle Roller Bearings are also referred to as track follower. They are designed to follow a sliding or rotating piece (cam) and they use rollers or needles as the rolling elements. Cam Follower Bearings are therefore able to replicate a specific motion because they are highly versatile. They have thick-walled outer rings that run on a track. They are used to minimize distortion and bending stress while facilitating high load carrying capacity.Generally speaking, cam follower bearings are designed in different configurations and special structures can be designed according to the task requirements.
