The NTN KR series cam follower is a roller bearing with an integrated stud and a threaded end, designed to work as a guide or cam roller on a raceway. It is mounted through plates or supports and secured with a nut, which simplifies the assembly of reciprocating mechanisms, linear guides and transfer systems. MR Accesorios Industriales sells it in Buenos Aires, Argentina.

The KR series designation is read from the number that follows the letters: that number indicates the roller's outside diameter in millimeters. Thus, the numbers following the letters KR correspond to the outside diameter in millimeters. The suffixes that appear after the number indicate variants of sealing, head shape or stud end, and it is advisable to verify them before requesting a quote because they define the mounting and the protection against contaminants.

These rollers are used in actuating cams, chain and belt guides, transfer systems, packaging machines, sheet feeders, handling equipment and industrial automation. In Argentina they appear in food production lines, bottling plants, metalworking shops and agricultural machinery manufacturers. Their threaded stud allows them to be mounted and removed without modifying the support, which is useful when the roller works against a cam or a guide that wears with use.

To choose well, take into account the outside diameter your mechanism needs, the type of sealing according to the environment (dust, chips, washdown) and the planned lubrication. The roller is secured with a nut on the stud thread and alignment with the raceway should be checked to avoid side loads. If the roller works against a cam, verify the profile and the mounting clearance. The KR series accepts different head and sealing configurations; send us the complete code and we will tell you which variant corresponds.

Cam followers are interchanged between brands by their dimensional designation: a KR with the same outside diameter number and the same stud type is usually equivalent between manufacturers, even if the sealing or head suffixes change. If you have an unidentified part, send us the main dimensions —outside diameter, stud diameter, thread and width— and we will quote the equivalent NTN reference. We can also evaluate interchangeability with other brands we sell.

If you already know the code, send it via WhatsApp to MR Accesorios Industriales and we will quote it promptly. If you are looking for a sealing or head variant that is not listed, write to us with the exact model and we will tell you the compatible alternative.
