CF Series Cylindrical Slot Type Flat Cam Follower Bearing CF20 CF20-1
Features of Flat Cam Follower
The cam follower is also called bolt type roller bearing. According to the internal rolling body, it is divided into three types: roller needle roller bearing, roller roller bearing and eccentric roller needle roller bearing. Because the bolt type roller bearing is like a bolt, one end has a thread , the other end has a hexagonal hole or a straight hole, so it is very convenient to install and replace, and most of NTN's roller bearings have been sealed and filled with grease, and a resin cage is used at the same time, so it is basically maintenance-free in the later stage.
