For tight radial spaces, the NTN HK series needle roller bearing offers a compact solution. It uses a stamped outer ring and no inner ring, so the shaft itself serves as the raceway. This design handles radial loads where the outside diameter must stay small. MR Industrial Accessories provides this series along with support to help you select the correct size for your equipment.

The HK series code follows a simple pattern. The letters HK stand for a needle roller bearing with a stamped outer ring and no inner ring. The numbers that follow give the bore and width in millimeters. Take 7E-HK3016C: the 7E prefix marks a special design, HK is the series, 30 is the bore diameter in millimeters, 16 is the width in millimeters, and the C suffix indicates a design variant. Once you know this structure, you can read any code in the series and order the exact replacement.

You will find these bearings in automotive, metallurgy, food processing, and textile plants. They appear in transmission boxes, pumps, compressors, machine tools, and conveyor systems. When radial space is limited but load capacity must remain high, the HK series is a common choice for repairs on packaging equipment and production lines.

Selecting the right HK bearing starts with the shaft diameter. The shaft must be ground and hard enough to act as a raceway. Check alignment between shaft and housing, because these bearings do not tolerate misalignment well. Lubrication can be grease or oil, and external seals provide sealing. Use suitable tools during mounting to avoid damaging the needles and the outer ring.

HK series needle roller bearings from different manufacturers share standardized dimensions, so they are interchangeable. If you are replacing a bearing from another brand, send us the code or the dimensions and we will identify the compatible alternative. MR Industrial Accessories will help you make a safe and effective replacement.
