A cam follower bearing, also known as a track follower bearing, is a specialized type of roller or needle bearing designed to follow cams or tracks. It typically consists of a thick-walled outer ring, known as the follower or outer race, which guides the bearing along the cam profile, and a needle or cylindrical roller set inside the outer ring, acting as the rolling elements. This design enables smooth motion even under high loads and varying speeds.

Cam follower bearings are commonly used in applications where precise and reliable linear or rotational motion is required, such as in cam-driven machinery, conveyor systems, printing presses, and automotive engines. They provide support and guidance to components moving along a predetermined path, ensuring smooth operation and reducing friction and wear.

These bearings are available in various configurations to suit different applications, including stud type and yoke type designs. Stud type cam followers have a threaded stud for mounting, while yoke type followers have a solid or split outer ring with a mounting hole for bolt-on installation. Their versatility, durability, and ability to handle heavy loads make cam follower bearings indispensable in numerous industrial and mechanical systems.
