When radial space is tight but loads are heavy, the NSK HJ series needle roller bearing is a practical choice. Its small-diameter cylindrical needles handle high radial loads within a compact envelope. You will find this series in gearboxes, pumps, compressors and textile machinery. MR Industrial Accessories LLC supplies these bearings and helps you match the right size to your application.

The HJ series code packs the bearing type and size into one string. Take HJ-101812: the HJ prefix marks the series, and the following digits outline the dimensions. Typically, the first group relates to bore, the next to outer diameter, and the last to width, but each reference has its own breakdown. For exact figures on any part number, we provide the corresponding data sheet with your quote.

In US plants and workshops, HJ series needle roller bearings show up in transmissions, machine tools, mining equipment and automotive assemblies. Their ability to carry radial loads in confined spaces suits camshafts, transmission shafts and steering mechanisms. Water pumps, industrial fans and packaging lines also rely on them where precision and durability keep production moving.

Selecting the right HJ bearing starts with the radial load, rotation speed and operating environment. Confirm shaft and housing diameters, plus the width you can accommodate. Proper installation calls for precise alignment and suitable lubrication—grease or oil—based on the application. Good sealing keeps contaminants out and helps the bearing last.

NSK HJ series bearings can be interchanged with other brands that share the same standardized dimensions. When comparing equivalents, look beyond dimensions to load capacity and cage type. If you have a competitor’s code or an unidentified part, send us the details and we will identify a compatible alternative from our range.
