The NTN KR series cam follower is a roller bearing with a cylindrical or crowned outer profile, designed to work directly on cams, linear guides or raceways. Its robust construction and sealing make it suitable for oscillating movements and combined loads in industrial machinery. MR Accesorios Industriales sells this series with the guarantee of a leading brand, backed by more than 80 years of experience in the field.
The KR series designation is read as follows: the letters KR identify an NTN brand cam follower. The number that follows indicates the outside diameter in millimeters, for example, KR30 corresponds to 30 mm. The XLL suffix indicates a special low-friction seal, while /3AS refers to a steel cage and guided rollers. Thus, a KR40XLL/3AS is a roller with 40 mm outside diameter 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 actuating cams, raceway guides and lifting mechanisms.
To correctly select a cam follower, take into account the outside diameter, the width and the type of sealing. The XLL suffix indicates a lip seal that retains grease and excludes contaminants, suitable for environments with dust or moisture. Mounting requires a ground support surface and precise alignment to avoid eccentric loads. Lubrication can be permanent or relubricable depending on the design.
As for equivalents, cam followers from other brands can be interchanged if the main dimensions and the type of sealing match. It is essential to verify the outside diameter, the total width and the bore diameter. For safe interchangeability, consult us: we will indicate the compatible alternative or quote the exact code you need.
