When radial room around a shaft is limited but the load is not, an NTN HMK series needle roller bearing is often the practical answer. It is a radial bearing that carries both an inner and an outer ring, so it handles high radial loads within a small outside diameter. Typical installations include transmissions, pumps, compressors and textile equipment. MR Industrial Accessories supplies the HMK line to customers throughout the United States and Latin America.

Reading an HMK reference is straightforward once you know the pattern. The letters HMK mark the family: needle roller bearings supplied with both rings. The four digits that follow carry the size information, split into two pairs. The first pair is the bore, the second is the width. Take HMK1416C: 14 mm bore, 16 mm width. HMK2025C follows the same logic, 20 mm bore and 25 mm width. A trailing C signals a design variant inside the series.

Where does this series fit? Automotive work, machine tools, transmission equipment, pumps, compressors and textile machinery all rely on it. In repair work it shows up in gearboxes, drive shafts and rotating assemblies where radial space is at a premium. A low profile combined with the ability to take high radial loads is what makes these bearings suitable for compact arrangements.

Selection comes down to three inputs: shaft diameter, the width you have available, and the radial load the bearing must carry. During assembly, shaft and housing need to be aligned precisely, and lubrication has to match the operating speed and temperature. How the position is sealed depends on the design of the application; adding external radial shaft seals is a common way to protect the bearing.

Bearings in the NTN HMK series can be swapped with equivalents from other manufacturers that use the same dimensional nomenclature. For a replacement, compare the dimensions that matter: bore, outside diameter and width. MR Industrial Accessories can help you locate the right equivalent from your part number or your measurements.
