When a shaft needs support but the surrounding space is too tight for a conventional ball bearing, the NTN HK FM series offers a practical answer. These radial needle roller bearings use a thin section and a stamped steel cage to carry high radial loads while keeping the outer diameter small. They are common in transmissions, electric motors, pumps, compressors and agricultural machinery. MR Industrial Accessories LLC supplies this series to customers across the United States and in several Latin American countries.

Reading the part number helps you confirm what you are ordering. The letters HK identify a cage-type needle roller bearing with standard dimensions. The digits that follow give the bore and width in millimeters. The FM suffix tells you the cage is stamped steel, a design suited to high speeds and moderate operating temperatures. With that structure, the main dimensions can be checked directly from the designation, without opening a catalog.

Typical applications include gearboxes, electric motors, centrifugal pumps, air compressors, machine tools, mining equipment and farm machinery. Because the bearing carries high radial loads in a low-profile section, it fits where a ball bearing would not. You will also find it in pulleys, gears and cam mechanisms, where precision and rigidity matter.

Selection comes down to radial load, rotation speed and the surrounding conditions. The stamped steel cage supports high speeds, but lubrication must match the operating regime, whether grease or oil. Mount the bearing with an interference fit on the shaft and maintain adequate radial clearance; poor alignment shortens service life. Since the HK series has no integrated seals, plan for external protection. In dirty environments, add radial shaft seals to keep contaminants out.

For interchangeability, other brands that follow the same dimensional designation can be considered, such as SKF, FAG, NSK or INA, as long as tolerances and load capacity are verified. Always confirm bore diameter, outer diameter, width, cage type and internal clearance. Our team can point you to a compatible alternative or quote the exact part number you need.
