When radial space is tight but radial load is high, the NTN HMK series needle roller bearing is a common choice. It is a radial bearing with both inner and outer rings, built to carry significant radial forces in a slim cross-section. You will find it in gearboxes, pumps, compressors and machine tools where rigidity matters. MR supplies this series to maintenance and purchasing teams across the US, Canada, Mexico and South America.

Reading the HMK code is straightforward once you know the pattern. The first pair of digits gives the bore diameter in millimeters, and the second pair gives the width in millimeters. Take HMK1825V2: it has an 18 mm bore and a 25 mm width. The V2 suffix marks a design variant within the series, which may relate to the cage style or how the needles are treated. If you need the exact meaning for a specific code, our technical team can confirm it.

These bearings show up in power transmission, agricultural machinery, mining equipment, cranes and lifting systems. They also serve in positive displacement pumps, screw compressors and machine tool spindles. Because they handle radial loads in a compact envelope, they are useful when a redesign calls for a smaller footprint without giving up capacity. MR supplies them for both replacement work and new projects.

Selecting the right HMK bearing comes down to radial load, rotation speed and the operating environment. In dusty or damp conditions, plan for extra sealing or a protected variant. Alignment between shaft and housing must be precise, as the needles do not tolerate misalignment well. Lubrication with grease or oil, chosen for the application, supports service life. Follow the manufacturer's guidance on internal clearance and fits.

HMK series bearings can be interchanged with equivalent products from other brands that use the same dimensional nomenclature. If you have a code from another maker or an unidentified part, send us the details and we will identify the compatible equivalent. To get the right part for your equipment, share whatever you have: dimensions, application and working conditions.
