The NTN support roller of the NUKR XH series 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 is mounted on a shaft by means of its threaded stud and 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 support roller with cylindrical rollers and a crowned outer profile; the X indicates that the outer surface is crowned to compensate for slight misalignments; the H corresponds to the stamped steel cage; and the suffix /3AS 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's outside diameter in millimeters. Thus, the series covers from 30 mm to 80 mm outside diameter.

These rollers are used in drive 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 factories. Their ability to withstand radial and shock loads makes them common in applications where there are impacts or reciprocating movements, such as in dies and cam mechanisms.

To select the right roller, take into account the outside diameter your application needs, the total width and the sealing type. The /3AS suffix indicates triple sealing, suitable for environments with dust or moisture. The H steel cage provides greater strength than polyamide cages. During mounting, ensure precise shaft alignment and adequate lubrication; the high-temperature grease is already incorporated, but in severe applications it may require relubrication. Verify the tightening torque of the lock nut.

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