The NSK MH series needle roller bearing is a radial needle roller bearing designed to handle high radial loads with a very compact cross-section. It is used in applications where radial space is limited and high load capacity is required, such as machine tools, transmission equipment and industrial mechanisms. MR Industrial Accessories sells this series across the USA, Canada, Mexico and South America, and advises you on choosing the correct designation for your application.

The MH series designation consists of the letters MH followed by a number that indicates the size and load capacity. For example, MH-571, MH-681 and MH-781 correspond to different shaft diameters and widths. Suffixes, when they appear, may indicate sealing, cage or special tolerance variants. To identify the exact size, it is necessary to consult the complete part number, since each number defines the main dimensions and load capacity.

These bearings are used in industries such as metalworking, food, textile and automotive. In the USA, Canada, Mexico and South America, they are commonly found in machine tool spindles, pumps, compressors, conveyor belts and packaging equipment. Their needle design allows them to handle high radial loads in tight spaces, making them ideal for applications where ball bearings do not have sufficient capacity.

To select the right bearing, consider the shaft diameter, radial load and lubrication conditions. The MH series may require oil or grease lubrication, and it is important to verify alignment and internal clearance. If the environment has contaminants, consider sealed variants. Mounting must be done with suitable tools to avoid damaging the needles and raceways.

Regarding equivalences, NSK MH series needle roller bearings can be interchanged with products from other brands that follow the same dimensional nomenclature, such as SKF, FAG or NTN, as long as the dimensions and load capacity match. It is essential to verify the complete part number and tolerances. If you have doubts, send us the original part number and we will indicate the compatible alternative.
