The NTN KR series cam follower is a roller bearing with a threaded stud, designed to be mounted directly on cams, linear guides or raceways. It is used in lifting mechanisms, conveyors and cam systems where high radial load capacity and rigidity are required. Its robust construction and LL sealing make it suitable for dusty environments and permanent lubrication. MR Accesorios Industriales sells this series in Buenos Aires, Argentina.

The KR series designation is read as follows: the letters KR identify a cam follower with a threaded stud. The number that follows indicates the outside diameter in millimeters; for example, KR30 corresponds to a roller with a 30 mm outside diameter. The LL suffix indicates that the bearing incorporates double-lip contact seals, and /3AS refers to a special design with a threaded stud and nut. Thus, a KR40LL/3AS is a roller with a 40 mm outside diameter, sealed, with a stud and nut for mounting.

These rollers are used in actuating cams, raceway guides, chain conveyors, packaging machines, lifting equipment and positioning systems. In Argentine industry they are found in automotive production lines, food plants, road machinery and metallurgical equipment. Their ability to withstand radial loads and tilting moments makes them ideal for mechanisms where space is limited and a robust, long-lasting support is needed.

To correctly select a KR cam follower, take into account the required outside diameter, the type of sealing (LL for contaminated environments), the stud thread and the recommended tightening torque. Mounting must ensure precise alignment with the raceway; excessive misalignment shortens service life. Lubrication is permanent in most sealed versions, but in severe applications relubrication through the stud may be required. Check concentricity and axial clearance according to the use.

Regarding equivalences, NTN KR cam followers are interchangeable with those of other brands that follow the same international nomenclature, such as SKF, INA or NSK, as long as dimensions and design match. When requesting a quote, provide the complete part number (for example, KR32LL/3AS) to ensure compatibility. If you are replacing a worn part, compare outside diameter, width, thread and type of sealing before installing.
