For equipment where radial room is tight but loads are still significant, the NTN HK series needle roller bearing is a practical option. It uses a stamped outer ring and comes without an inner ring, so the shaft surface acts as the raceway. This construction suits machine tools, transmissions, pumps and similar industrial machinery.

Reading an HK part number is straightforward once you know the pattern. The letters HK identify a needle roller bearing with a drawn or stamped outer ring. The first digits give the bore in millimeters, and the second group gives the width in millimeters. Take HK2526C: bore 25 mm, width 26 mm. The C at the end points to a design variation, which could involve the cage style or a surface treatment. If the suffix is unclear, ask our team to confirm what it means for the exact part you need.

These bearings appear in many industrial settings. Machine tools such as drills and milling machines use them, as do power transmissions, pumps, compressors and linear motion systems. In the automotive field, they are common in gearboxes and steering assemblies. The compact envelope allows them to fit where a larger bearing would not, while still carrying the radial load the application demands.

Selection depends on three main inputs: shaft diameter, bearing width and the conditions the bearing will see in service. Check that lubrication is appropriate, since HK bearings typically run with grease or oil. During mounting, take care not to damage the needles or the outer ring. Shaft-to-housing alignment also matters for smooth running and long service life. When any of these points is uncertain, our technical team can help review the application.

Interchangeability is another consideration. NTN HK series bearings follow the same international nomenclature as other brands, so equivalents are often available. Even so, tolerances and technical details can differ between manufacturers, so verify the fit before substituting. We can advise on a suitable alternative when you provide the part number or dimensions.
