The NTN HMK series is a single-row radial needle roller bearing that combines a machined outer ring with a steel cage. This construction delivers high radial load capacity within a very small radial envelope, making it suitable for arrangements where the shaft diameter is large relative to the housing. Typical uses include gearboxes, pumps, compressors and machine tools. MR Industrial Accessories LLC supplies the HMK series to customers throughout the United States and in several Latin American countries.

Reading an HMK code helps you confirm dimensions before ordering. The letters HMK denote the series: needle roller bearing with a machined outer ring and a steel cage. The digits that follow give the bore diameter in millimeters and then the total width. In 7E-HMK3520B, the 7E prefix is a design variant, HMK is the series, 35 is the 35 mm bore and 20 is the 20 mm width. The B suffix indicates a modification to the contour or cage. This structure lets you identify the main dimensions at a glance.

HMK series bearings are found in transmissions, hydraulic pumps, air compressors, textile machinery, mining equipment and automotive assemblies. Because they handle high radial loads with minimal radial space, they suit shafts of considerable diameter inside compact housings. They also appear in conveyor rollers, pulleys and cam systems. MR Industrial Accessories LLC serves workshops, factories and production plants across the United States and Latin America.

Selection depends on shaft diameter, housing width and expected radial load. Confirm that the shaft has the correct hardness and roughness to act as a raceway, since these bearings are often mounted directly on the shaft. Lubrication matters: use quality grease or oil and maintain a continuous lubricant film. Shaft-to-housing alignment must be precise to avoid parasitic axial loads. In contaminated environments, consider additional seals. Mount with suitable tools and avoid direct blows on the cage.

NTN HMK series bearings can be interchanged with equivalent products from other manufacturers that follow the same dimensional nomenclature. When you request a quote, provide the complete code including prefixes and suffixes so compatibility can be verified. Alternatives with the same critical dimensions and load capacity may be available. MR Industrial Accessories LLC has experience with cross-manufacturer equivalents and can help you find the right solution.
