cam and follower

grabcad

The cam-and-follower mechanism, also known as a cam drive or eccentric drive, is an essential component in numerous mechanical systems. It consists of a cam that has a specific shape (profile), which, when rotated, causes a follower to move along its axis in a predetermined path. This motion can be linear, circular, or any other complex pattern, depending on the design of the cam. The movement of the follower is what drives other parts of the system, making it an essential part of many machines.
