The NTN KR XH series cam follower is a roller bearing with an optimized outer profile for direct contact on cams, raceways and linear guides. It mounts on a fixed stud or pin and withstands radial loads combined with shock forces, typical of cam drive mechanisms. Its robust and sealed design makes it suitable for environments with dust, chips and permanent lubrication. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission.

The KR XH series designation is read as follows: KR indicates a cam follower with a stud or pin; the number that follows, as in KR30XH or KR40XH, corresponds to the outside diameter in millimeters; the X indicates the cylindrical outer profile; and the final H identifies the variant with reinforced sealing and steel cage. Thus, KR52XH and KR62XH share the same construction logic, varying only in size. This nomenclature allows you to order the exact code 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 outside 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 working regime. 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, provided the outside diameter, width and stud type match. If you have the code from another brand or an unidentified part, send us the main dimensions and we will indicate the compatible equivalent. MR Accesorios Industriales advises you so that the replacement works without modifying the housing.

If you need to request a quote for an NTN KR XH series cam follower, write to us via WhatsApp with the complete code, for example KR35XH or KR72XH, or with the dimensions of the part you want to replace. We will quote you promptly and indicate the compatible alternative if applicable. MR Accesorios Industriales, Buenos Aires, Argentina, with more than 80 years supporting industry.
