The NTN KR series cam follower is a roller bearing with a cylindrical or crowned outer profile, designed to run directly on cams, linear guides or raceways. Its robust construction and sealing make it suitable for oscillating motion and combined loads in industrial machinery. MR Accesorios Industriales sells this series backed by a leading brand.
The KR series designation is read as follows: the letters KR identify an NTN cam follower. The number that follows indicates the outer diameter in millimeters. The XLL suffix indicates a special low-friction seal, while /3AS refers to a steel cage with guided rollers. Thus, a KR40XLL/3AS is a 40 mm outer diameter roller with XLL sealing and /3AS cage.
These rollers are used in a wide variety of industrial applications in Argentina: from machine tools and automation equipment to conveyors, presses and cam systems in the food, textile and automotive industries. Their ability to withstand radial and axial loads makes them ideal for drive cams, rolling guides and lifting mechanisms.
To correctly select a cam follower, take into account the outer diameter, width and type of sealing. The XLL suffix indicates a lip seal that retains grease and excludes contaminants, suitable for dusty or humid environments. Mounting requires a ground support surface and precise alignment to avoid eccentric loads. Lubrication can be permanent or relubricable depending on the design.
Regarding equivalents, cam followers from other brands can be interchanged if the main dimensions and type of sealing match. It is essential to verify the outer diameter, total width and bore diameter. For safe interchangeability, consult us: we will indicate the compatible alternative or quote the exact part number you need.
