The NTN HMK series needle roller bearing is a single-row radial bearing with a steel cage and a machined outer ring. Its compact design allows high radial load capacities in very small radial spaces. It is used in applications where the shaft must have a large diameter in relation to the housing, such as gearboxes, pumps, compressors and machine tools. MR Accesorios Industriales sells the HMK series in Buenos Aires, Argentina.

The HMK series designation is read as a code that combines letters and numbers. The letters HMK identify the series of needle roller bearings with a machined outer ring and a steel cage. The numbers that follow indicate dimensions: the first two digits correspond to the bore diameter (in millimeters) and the next two to the total width. For example, in 7E-HMK3520B, the prefix 7E indicates a design variant, HMK the series, 35 the bore diameter (35 mm) and 20 the width (20 mm). The suffix B indicates a modification in the contour or in the cage. This nomenclature lets you quickly identify the main dimensions.

In Argentine industry, HMK series needle roller bearings are used in transmissions, hydraulic pumps, air compressors, textile machines, mining equipment and automotive applications. Their ability to withstand high radial loads with little radial space makes them ideal for shafts of considerable diameter inside compact housings. They are also used in conveyor rollers, pulleys and cam systems. MR Accesorios Industriales supplies this series to workshops, factories and production plants throughout the country.

To correctly select an HMK bearing, take into account the shaft diameter, the housing width and the expected radial load. Check that the shaft has the right hardness and roughness to serve as a raceway, since these bearings are usually mounted directly on the shaft. Lubrication is critical: use quality grease or oil and ensure a continuous lubricant film. The alignment between shaft and housing must be precise to avoid parasitic axial loads. If the environment has contaminants, consider additional seals. Mounting is done with suitable tools, avoiding direct blows on the cage.

NTN HMK series needle roller bearings can be interchanged with equivalent products from other brands that follow the same dimensional nomenclature. When requesting a quote, it is essential to provide the complete code, including prefixes and suffixes, to ensure compatibility. Alternatives with the same critical dimensions and load capacity can be offered. MR Accesorios Industriales has extensive experience in equivalents between manufacturers and can advise you to find the right solution.
