The INA HK TV series needle bushing is a very thin-section radial bearing with a stamped steel cage and guided needles that mounts directly on the shaft without an inner ring. It is used to support radial loads in tight spaces where a ball bearing will not fit. It is common in small electric motors, pumps, compressors, packaging machines and power transmission equipment. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina.

The HK TV series designation is read in parts: HK identifies the thin-walled needle bushing; the numbers that follow indicate, in millimeters, the bore diameter and the width of the part; the TV suffix corresponds to the stamped steel cage, which guides the needles and allows higher speeds than a plastic cage. For example, HK0205-TV and HK0306-TV are standard sizes in the series, and the complete part number is built from those digits. To order the replacement, provide the part number exactly as it appears on the drawing or on the old part.

This type of bushing is used in applications where radial space is critical: low-power electric motors, centrifugal pumps, air compressors, conveyor belts, packaging machines and power transmission equipment. In Argentina, it is commonly found in the metalworking, food and automotive sectors, both in production lines and in equipment maintenance. Because it has no inner ring, the shaft acts as the raceway, which requires it to be hardened and ground.

To select the correct bushing, take into account the shaft diameter, the available width and the radial load it will support. The shaft raceway must have adequate hardness and surface roughness; if not, a version with an inner ring should be used. Mounting is done by press fit or with a mounting tool, without striking the needles directly. Lubrication can be grease or oil, depending on the operating conditions, and the alignment between shaft and housing must be careful to avoid parasitic axial loads.

Needle bushings are interchanged between manufacturers by their dimensional designation: the same size code may correspond to different brands, but the internal suffixes, the cage and the tolerances change. Therefore, when replacing, verify not only the diameter and width, but also the cage type and radial clearance. At MR Accesorios Industriales we supply INA as an official brand and can guide you if the original part number is not available.
