1. Knife-edge follower: - It is simple in construction it is pointed at one end; it produces a great wear at the surface of point of contact.
2. Roller follower: - It is widely used follower and has a cylindrical roller free to rotate about a pin joint, it has pure rolling action, but at high speeds sliding also occurs.
3. Mushroom follower: - This type of follower does not cause the problem of jamming the cam, it has high surface stresses and wear so instead flat-faced follower is used.
According to movement: -
1. Reciprocating follower: - In this type the cam oscillates and the follower reciprocates or oscillates.
2. Oscillating follower: - In this the follower is pivoted at one point and frame oscillates as the cam makes a rotary motion.
According to location of line of movement: -
1. Radial follower: - In this the line of movement of follower passes through center of rotation of cam.
2. Offset follower: - In this the line of movement of roller follower is offset from center of rotation of cam.
