The NTN NUKR XH series cam follower is a cylindrical roller bearing with a crowned outer profile, designed to withstand high radial loads and allow the movement of cams, guides and cam systems. It mounts on a shaft via its threaded stud and is secured with a nut. Its robust construction makes it suitable for demanding applications in industrial machinery, where high load capacity and fatigue resistance are required.

The NUKR XH series designation reads as follows: NUKR indicates a cam follower with cylindrical rollers and a crowned outer profile; the X indicates that the outer surface is crowned to compensate for minor misalignments; the H corresponds to the stamped steel cage; and the /3AS suffix identifies the triple seal with high-temperature grease. Examples such as NUKR30XH/3AS or NUKR80XH/3AS show that the middle number (30, 80) is the roller outer diameter in millimeters.

These rollers are used in actuating cams, linear guides, chain conveyors, packaging machines, presses, mining equipment and lifting systems. In Argentine industry they appear in automotive production lines, food plants, cement plants and steel mills. Their ability to withstand radial and shock loads makes them common in applications with impacts or reciprocating motion, such as dies and cam mechanisms.

To select the correct roller, take into account the outer diameter your application requires, the overall width and the type of sealing. The /3AS suffix indicates triple sealing, suitable for dusty or humid environments. The H steel cage provides greater strength than polyamide cages. During mounting, ensure precise shaft alignment and adequate lubrication; high-temperature grease is already incorporated, but severe applications may require relubrication. Check the tightening torque of the lock nut.

NTN NUKR XH series cam followers are interchangeable with those from other brands that follow the same dimensional nomenclature, such as SKF, FAG or NSK. If you have another brand's part number, we can identify the exact equivalent. Interchangeability is based on outer diameter, width and stud type dimensions. Always confirm tolerances and load capacity before replacing one roller with another, as they may vary between manufacturers.
