For machinery that relies on cam-driven motion, the NTN KR series cam follower provides a roller bearing with either a cylindrical or crowned outer profile. It runs directly on cams, linear guides or raceways, and its construction and sealing suit oscillating movement and combined loads. MR Industrial Accessories LLC supplies this series to customers across the United States and Latin America.
Decoding the part number helps you confirm the right roller. KR identifies an NTN cam follower. The following number is the outer diameter in millimeters. The XLL suffix denotes a special low-friction seal, and /3AS indicates a steel cage with guided rollers. For example, a KR40XLL/3AS has a 40 mm outer diameter, XLL sealing and a /3AS cage.
These cam followers appear in machine tools, automation equipment, conveyors, presses and cam systems in the food, textile and automotive sectors. Because they accommodate radial and axial loads, they are well suited to drive cams, rolling guides and lifting mechanisms.
Selection depends on outer diameter, width and sealing type. The XLL lip seal keeps grease in and contaminants out, making it a fit for dusty or humid environments. Mounting calls for a ground support surface and precise alignment to prevent eccentric loads. Lubrication may be permanent or relubricable, depending on the design.
Interchange with cam followers from other brands is possible when the main dimensions and sealing type align. Check the outer diameter, total width and bore diameter. For a safe match, contact us and we will identify a compatible alternative or quote the exact part number.
