The NTN HMK series needle roller bearing is a component with a reduced radial section that is used to support radial loads in spaces where a conventional bearing does not fit. Its needle design allows high load capacity in a compact outside diameter, ideal for applications with small-diameter shafts or tight transmission cases. MR Accesorios Industriales sells this series with the backing of more than 80 years in the industrial sector.

The HMK series designation is interpreted as follows: the letters HMK identify NTN's family of needle roller bearings with a steel cage, and the numbers that follow indicate the main dimensions, as in HMK1920F or HMK2525F. The F suffix indicates a construction variant within the series, generally linked to the type of seal or cage. To select the correct code, have the shaft diameter and the housing dimensions at hand.

These bearings are used in industries such as automotive, machine tools, power transmission equipment, pumps and compressors. In Argentina, they are common in gearbox repairs, electric motors and agricultural machinery, where radial space is critical. Their ability to support high radial loads with low friction makes them suitable for moderate and high speed regimes.

For a correct selection, check the radial load and the lubrication conditions. The HMK series is usually mounted with an interference fit on the shaft and clearance in the housing. If the environment has contaminants, consider additional sealing. Alignment between shaft and housing is essential to avoid premature wear. Lubrication can be grease or oil, depending on the application and the rotation speed.

As for equivalents, needle roller bearings from other brands with similar dimensions can be interchanged, but always check tolerances and load capacity. NTN's HMK series is a reliable reference on the market. If you need to replace a bearing from another brand, send us the code and the dimensions so we can quote the corresponding option.
