The INA KR-PP cam follower is a stud-type roller bearing with seals on both sides, built for radial loads in cam drives and support roles. It suits guidance systems, cam tracks and mechanisms that call for a sturdy roller with low friction. Sealing keeps contaminants out and supports dependable running in tough conditions. MR Industrial Accessories supplies this series to customers in the United States and Latin America.
Reading the code is straightforward. KR stands for cam follower. The figure that follows is the outside diameter in millimeters. The PP suffix means contact seals sit on both sides of the roller. So KR16-PP measures 16 mm across the outside diameter, KR22-PP measures 22 mm and KR40-PP measures 40 mm. This structure lets you identify size and sealing at a glance, which helps when matching a replacement to an existing position.
Typical uses cover machine tools, packaging lines, conveyors, cam systems in engines, presses, cranes and linear motion equipment, plus automotive, food and metallurgical operations. Because these rollers take radial loads and moderate axial loads, they work well for guiding moving parts and transmitting force in oscillating mechanisms.
When choosing a size, look at the outside diameter you need, whether PP sealing fits the environment, the radial and axial loads involved and the running speed. Installation should keep the shaft aligned and lubrication in good condition. INA rollers arrive factory-lubricated, yet some applications still call for relubrication over time. Check axial fixing and internal clearance as well.
Cam followers from other makers can carry similar designations, so confirm dimensions and load ratings before swapping. The INA KR series matches other rollers that use the same nomenclature, though suffixes differ between brands. It is worth checking with a specialist before you interchange.

Frequently asked questions
- What does the PP suffix mean on KR rollers?
- PP means contact seals are fitted on both sides, adding protection against dust, dirt and moisture and helping the bearing last longer in contaminated settings.
- Are INA KR-PP rollers shipped with grease?
- Yes, they come factory-lubricated with high-quality grease. In severe applications, periodic relubrication may still be required depending on working conditions.
- How do I determine the KR roller size I need?
- The number in the designation gives the outside diameter in millimeters. Measure the outside diameter your application requires and select the matching part number. If unsure, send your measurements by WhatsApp and we will advise.
