Cam followers and track rollers provide antifriction solutions for translating rotation to linear motion or supporting either pure radial or combination thrust loads depending on the rolling elements types. Cam follower bearings reduce sliding friction and wear on the cam and track, which allows it to maintain its precision. The type of bearing used affects the cam follower’s performance. To select the right cam follower bearing for a cam or track system, consider the load magnitude and type, speed, deflection, misalignment and lubrication.
Our range of offerings for specialized and heavy-duty applications includes maintenance-free, corrosion resistant and extreme-temperature designs incorporating advances in treated stainless steel and manufacturing processes. By matching the wider range of designs to specific applications with proper installation, alignment, and lubrication, today’s cam follower bearings offer better performance with longer working lives.
The unmounted bearing assembly consists of hardened precision ground inner and outer raceways. They also have either full complement or separated needle, ball, tapered, or cylindrical rolling elements constructed with an integrated stud. Heavy stud versions are for heavy loads, shock loading and applications requiring minimal deflection. Except for the stud diameter and end plate design, standard and heavy stud versions are virtually identical.
The unmounted bearing assembly consists of hardened precision ground inner and outer raceways. They also have either full complement or separated needle, ball, tapered, or cylindrical rolling elements. These elements are constructed with an integral precision ground bore for optimal installation. Yoke rollers distribute loads more uniformly over the bearing, so the working load limit for yoke-type followers are generally equal to that of heavy stud followers.
Choosing the Right Cam-Follower Bearing
To get the most out of cam followers, engineers should know the different variations and factors that affect performance and operational life.
Cam followers convert rotary to linear motion and range from simple two-dimensional cams to complex three-dimensional indexing cams with several followers. In linear-motion applications, cam followers support lateral or vertical travel, such as rollers for platform support and die transfer. In any application, cam follower bearings reduce sliding friction and wear on the cam and track, which lets it maintain its precision. Overall, the choice of which type of bearing is used affects the cam follower’s performance.
