The INA HK TV needle bushing is a radial bearing with a very thin wall, a stamped steel cage and guided needles. It mounts straight onto the shaft and does without an inner ring, which makes it a fit for radial support where a ball bearing would take up too much room. You will see it in small electric motors, pumps, compressors, packaging machinery and power transmission equipment. MR Industrial Accessories LLC supplies this INA line to customers throughout the United States and in several Latin American countries.

Reading the HK TV code helps you order the right part. HK marks the thin-walled needle bushing. The digits after it give, in millimeters, the bore diameter and then the width. The TV suffix tells you the cage is stamped steel, which guides the needles and suits higher speeds than a plastic cage. Standard sizes in the series include HK0205-TV and HK0306-TV, and the full part number comes from those digits. When you request a replacement, copy the part number exactly as it appears on the drawing or on the part you are removing.

These bushings suit spots where radial room is tight: low-power electric motors, centrifugal pumps, air compressors, conveyor belts, packaging machines and power transmission equipment. Because there is no inner ring, the shaft itself serves as the raceway, so it has to be hardened and ground.

Selection comes down to shaft diameter, the width you can accommodate and the radial load the bushing will carry. Check the shaft raceway for hardness and surface roughness; if it does not meet those conditions, choose a version with an inner ring instead. Press it in or use a mounting tool, and never strike the needles directly. Grease or oil both work as lubrication, depending on operating conditions, and shaft-to-housing alignment needs care so you do not introduce parasitic axial loads.

Needle bushings interchange between manufacturers by dimensional designation. The same size code can appear across different brands, but internal suffixes, cage type and tolerances vary. When you replace one, confirm the cage type and radial clearance along with the diameter and width. MR supplies INA as a brand and can point you to the right reference.
