The INA HK series covers radial needle roller bearings that use a drawn cup outer ring and no inner ring. The shaft itself serves as the raceway, which keeps the bearing compact where radial space is tight. These units press into a machined housing with an interference fit and suit applications that need high load capacity in a small envelope. MR Industrial Accessories supplies this line and can assist with part number selection.

The part number follows a simple pattern. The first pair of digits gives the shaft diameter in millimeters, and the second pair gives the drawn cup width. HK0408, for instance, is built for a 4 mm shaft with 8 mm width, while HK0810 takes an 8 mm shaft and 10 mm width. That numbering lets you identify a size without consulting a table.

Typical installations include transmissions, pumps, compressors, machine tools and packaging equipment. They also show up in conveyor rollers, joints and lifting mechanisms. Because there is no inner ring, the shaft must be ground and hard enough to work as a raceway. These bearings are often chosen when a bushing is being replaced and space is limited.

Selection comes down to shaft diameter and tolerance, the width available and the load type. Press the bearing into the housing using tooling that will not deform the drawn cup. Grease or oil both work for lubrication, depending on the environment; in contaminated areas, external seals or sealed versions are worth considering. Shaft and housing alignment matters to prevent edge loads. If the shaft is not hardened, a version with an inner ring is the better choice.

Interchange between manufacturers is usually based on the dimensional part number: the same shaft diameter and width often has equivalents in other brands. Before substituting, compare tolerances, load capacity and the drawn cup type. For equivalents, the safest approach is to match the full designation and confirm with the supplier.
