The INA HN series needle bushing is a radial bearing with a very small cross-section: a cage with needles that mounts directly on the shaft, without an inner ring. It is used when radial space is limited and high load capacity is required. MR Accesorios Industriales sells this line, with technical advice to choose the correct part number.

The HN series designation reads as a size code: the letters identify the design type and the numbers that follow indicate standardized dimensions. For example, HN0808, HN1210 or HN2020 refer to different bushing sizes. In this series there are no additional suffixes in the available examples; the numeric code is the key to identifying the exact size. To request a quote, send us the complete part number shown on your drawing or on the original part.

These bushings are used in compact transmissions, machine tools, packaging equipment, pumps, gearboxes and mechanisms where axial and radial space is critical. In Argentina they are found in production lines, road and agricultural equipment, and in maintenance of imported machinery. Their low profile allows replacing conventional bushings or bearings when there is no room for inner rings.

To select the correct bushing, take into account the shaft diameter and length, the radial load and the lubrication conditions. The raceway on the shaft must have adequate hardness and roughness; if not, an inner ring should be used. Mounting is done by press fit or with insertion tools, taking care with alignment so as not to damage the needles. Lubrication can be grease or oil, depending on speed and environment.

As for equivalents, needle bushings are interchangeable between manufacturers if the standardized dimensions and the design type match. The diameter alone is not enough: width, tolerances and load capacity must be verified. MR Accesorios Industriales sells INA and can advise you on options that correspond in the local market, always respecting the specifications of your equipment.
