The NTN KR XH series cam follower is a roller bearing with an outer profile optimized for direct contact on cams, raceways and linear guides. It mounts on a fixed shaft or stud and withstands radial loads combined with shock stresses, typical of cam-driven mechanisms. Its robust design and sealing make it suitable for environments with dust, chips and permanent lubrication. MR Accesorios Industriales sells this series in Buenos Aires, Argentina.

The KR XH series designation is read as follows: KR indicates a cam follower with a stud or pin; the number that follows corresponds to the outer diameter in millimeters; the X indicates the cylindrical outer profile; and the final H identifies the variant with reinforced sealing and steel cage. Thus, the different part numbers share the same construction logic, varying only in size. This nomenclature lets you request the exact part number shown on the drawing or on the machine.

In Argentine industry, NTN KR XH series cam followers are used in machine tool cams, transfer systems, presses, packaging equipment and automated assembly lines. They also appear in lifting guides, transport rails and indexing mechanisms, where direct rolling on a hardened raceway replaces sliding bushings. Their ability to withstand radial and impact loads makes them common in the metalworking, food and automotive sectors.

To select the correct roller, take into account the outer diameter your application needs, the type of sealing required according to the environment (dust, water, temperature) and the internal clearance suitable for the rotation speed. Mounting requires a hardened and ground support surface, with precise alignment with respect to the cam or guide. Lubrication must be the one indicated by the manufacturer and renewed according to the duty cycle. Misaligned mounting accelerates wear of the profile and the seal.

NTN KR XH series cam followers are interchangeable with those from other brands that follow the same dimensional nomenclature, such as the KR series from INA or SKF, as long as outer diameter, width and stud type match. If you have another brand's part number or an unidentified part, send us the main dimensions and we will indicate the compatible equivalent. MR Accesorios Industriales advises you so the replacement works without modifying the housing.
