The SKF KR PP series cam follower roller is a roller bearing with an integrated stud and cylindrical outer surface, designed to support radial loads and transmit motion in cam mechanisms. It mounts directly on the equipment shaft and is fixed with a nut, which simplifies assembly. It is a robust solution for linear guiding, actuating cams and conveying systems in industrial machinery. MR Accesorios Industriales carries this SKF line with technical advice to select the right part number.

The designation KR identifies a cam follower roller with an integrated stud and needle cage. The number that follows indicates the outside diameter in millimeters: for example, KR 16 PP has a 16 mm outside diameter, KR 22 PP 22 mm and KR 40 PP 40 mm. The suffix PP indicates that the roller incorporates contact seals on both sides, which retains lubricant and blocks contaminants. This nomenclature lets you quickly read the size and protection of the roller, making replacement easier without having to measure the part.

These rollers are used in actuating cams, slide guides, chain conveyors, packaging machines and automation equipment. In Argentine industry they appear in automotive assembly lines, machine tools, material handling equipment and cutting systems. Their ability to support radial loads and some axial thrust makes them suitable for applications requiring a compact bearing that is easy to mount on sheet metal or welded structure.

To select the roller, consider the outside diameter your cam or guide needs, the width of the raceway and the expected radial load. The PP sealing is recommended in environments with dust or moisture; if the roller works in clean areas at high speeds, a variant without seals can be evaluated. Mounting is done on a shaft with a fit and fixed with a nut; it is important to align the raceway to avoid excessive side loads. The lifetime lubrication that the sealed roller comes with simplifies maintenance.

When looking for equivalents, keep in mind that each manufacturer uses its own nomenclature for cam follower rollers. The SKF KR series corresponds to stud-type rollers from other suppliers, but the part numbers are not directly interchangeable: you must verify outside diameter, width, type of sealing and stud thread.
