Cam followers, or cam rollers / track followers, are designed for automated systems that have a cam drive mechanism. These cam followers are a type of needle roller or cylindrical roller bearing that can run on different types of track or cam lobe profiles. What defines a cam follower is its stud type- either standard stud hexagon hole or with a screwdriver slot type. Its outer ring that makes direct contact with the mating cam guide surface is also characterised by either a crowned or cylindrical outer ring. These cam followers are all available in carbon steel or stainless steel.
