Cam follower rollers in the SKF KR PP series combine a stud-type roller bearing with a cylindrical running surface. They handle radial loads and transmit motion in cam drives, and they mount straight onto a shaft and secure with a nut. The design suits linear guiding, cam actuation and conveying equipment in industrial plants. MR Industrial Accessories supplies this SKF line and assists with part number selection.
Reading the code: KR stands for a cam follower roller with an integral stud and needle cage. The digits that follow give the outside diameter in millimeters. So KR 16 PP measures 16 mm across, KR 22 PP measures 22 mm, and KR 40 PP measures 40 mm. The PP suffix means contact seals sit on both sides, keeping lubricant in and contaminants out. This naming system lets you identify size and sealing at a glance, which simplifies replacement without measuring the old roller.
Typical installations include cam drives, slide guides, chain conveyors, packaging lines and automation systems. They also appear in machine tools, material handling equipment and cutting stations. Because the roller supports radial loads and takes some axial thrust, it fits where space is tight and mounting on sheet metal or welded frames must be straightforward.
When choosing a roller, match the outside diameter to your cam or guide, check the raceway width, and estimate the radial load. The PP seals are the right choice for dusty or damp conditions; in clean, high-speed areas a version without seals may be considered. Mount the roller on a shaft with the correct fit and lock it with a nut. Align the raceway carefully to prevent excessive side loads. The sealed roller comes with lifetime lubrication, which reduces maintenance work.
If you are cross-referencing, remember that cam follower rollers use different codes across manufacturers. The SKF KR series is equivalent in function to stud-type rollers from other suppliers, but part numbers do not swap directly. Confirm outside diameter, width, seal type and stud thread before substituting.

Frequently asked questions
- What does the PP suffix indicate on KR rollers?
- PP means the roller has contact seals on both sides. This keeps dust and moisture out and retains grease, making it suitable for dirty or wet environments.
- How do I pick the right KR roller size?
- The number in the part number is the outside diameter in millimeters. Measure the diameter of the cam or raceway where the roller will run and select the matching size. Also check the width and stud thread.
- Can I replace another brand's roller with a KR PP?
- Not by part number alone. Each maker uses its own coding. Compare outside diameter, width, sealing type and thread. Contact MR to confirm the equivalent.
