Now that you have a better understanding of what a cam is, it’s time to talk about cam followers. In order to transfer that rotary motion to linear motion (or vice versa), the cam needs to make contact with what’s known as a cam follower.

In the image below, the grey objects are the cams, and the orange objects are the cam followers (flat-ended cam followers, to be exact).

Cam follower bearings are also known as track followers. As the name implies, they are essential to make the cam followers work effectively. Cam followers are capable of handling intermittent shock and heavy loads. They also can have a soft core that allows for extreme shock loads without fracture. There are two types of cam follower bearings: stud style or yoke style.
