The NTN cam follower of the KRV series is a roller bearing with its own stud, designed to work supported directly on a cam, a guide or a rolling track. It is mounted with the stud fixed to the support and the outer raceway rotating against the contact surface, which allows transmitting motion with low friction in actuation and positioning mechanisms. MR Accesorios Industriales is an official distributor of NTN and sells this line, with technical advice to choose the right size.

The designation of the KRV series is read in blocks: the letters identify the family of stud-type cam followers, the number that follows indicates the roller's outer diameter and the suffixes define the type of raceway and the sealing. In the examples KRV16F/3AS, KRV19F/3AS, KRV22F/3AS and KRV26F/3AS, the F indicates the cylindrical outer raceway and the /3AS set corresponds to the sealing and the mounting configuration. With that data the exact reference within the series is located.

These rollers are used in actuation cams, linear guides, conveyors, packaging machines, cutting equipment and positioning mechanisms. In Argentine industry they appear in food production lines, plastics plants, machine tools and continuous motion equipment, where the outer raceway must roll precisely on a hardened, well-aligned surface.

To select well, take into account the roller's outer diameter, the stud diameter and length, the type of raceway (cylindrical or crowned) and the sealing. The /3AS suffix defines protection against contaminants; in environments with dust or chips it is advisable to verify that point. Mounting requires aligning the stud axis with the rolling track and adjusting the preload according to the load, with proper lubrication and without impacts that mark the raceway.

Equivalences between brands are resolved by dimensions and configuration: a cam follower from another firm with the same outer diameter, stud diameter and type of raceway can be interchanged, but tolerances and sealing must be compared. If you bring another brand's code or an unidentified part, at MR Accesorios Industriales we will tell you the compatible alternative and quote it for you.

To move forward, send us on WhatsApp the complete code (for example KRV22F/3AS) or the dimensions of the roller you need. We will quote it promptly and advise you on the variant that best suits your mechanism.
