The NTN NUKR H/AS series cam follower is a cylindrical roller bearing with a crowned outer profile, designed to withstand high radial loads in cam and guidance applications. Its robust construction and integrated sealing make it suitable for machinery subjected to repetitive stresses and environments with moderate contamination. It is used as a cam follower in transmission systems, linear guides and lifting mechanisms. MR Accesorios Industriales sells this series in Buenos Aires, Argentina.

The NUKR H/AS series designation is interpreted as follows: NUKR identifies a cam follower with cylindrical rollers, steel cage and crowned outer profile; the letter H indicates that the roller has a lubrication groove and hole at the end; AS indicates that it incorporates nitrile contact seals on both sides. The numbers appearing in the examples — such as 30, 35, 40, 47, 52, 62, 72 or 80 — correspond to the roller outer diameter in millimeters, depending on the part number. Thus, an NUKR30H/3AS has a 30 mm outer diameter, while an NUKR80H/3AS reaches 80 mm. This nomenclature allows you to quickly identify the size and the sealing and lubrication characteristics.

In Argentine industry, NTN NUKR H/AS series cam followers are used in a wide variety of applications. They are common in packaging machines, conveyor belts, lifting equipment and cranes, presses, and production line guidance systems. They also appear in the food industry, where corrosion resistance and ease of cleaning are important, and in the metalworking sector for cam and follower mechanisms. Their ability to withstand radial and moderate axial loads makes them versatile in equipment where space is limited and precise movement is required.

To correctly select a cam follower from this series, take into account the radial load it will have to withstand, the rotation speed and the environmental conditions. The AS sealing protects against dust and moisture, but if there is exposure to aggressive chemical agents or extreme temperatures, it is advisable to evaluate an alternative seal material. Mounting must be done on a shaft with the proper fit, verifying alignment to avoid eccentric loads that reduce service life. Lubrication is essential: the H groove facilitates periodic greasing, which must be done with the lubricant recommended by the manufacturer. Careful mounting and a preventive maintenance plan extend the bearing's life.

Regarding equivalents and interchangeability, NTN NUKR H/AS series cam followers can be replaced by products from other manufacturers that follow the same international nomenclature. Brands such as SKF, FAG, INA or NSK offer rollers with similar designations, although they may vary in construction details such as seal type or tolerance. It is always advisable to verify the critical dimensions — outer diameter, inner diameter and width — and the load conditions before replacing a part.
