The INA IR series needle roller bearing is an inner ring that is mounted on the shaft to serve as a raceway for the needles. It is used when the shaft is not hardened or ground and a hard, precise raceway surface is needed. MR Accesorios Industriales carries this INA line in Buenos Aires, Argentina, with technical advice to choose the correct size according to the part number.

The IR series designation is read as a size reference: the letters identify the type of inner ring and the numbers that follow indicate the shaft diameter or the nominal size, as applicable. That is why it is advisable to send the complete part number, for example IR5, IR6, IR7, IR8, IR9, IR10, IR14 or IR15, so that MR Accesorios Industriales can confirm the exact equivalence and the availability of that particular size.

These rings are used in machine tools, transmission equipment, pumps, compressors, conveyor belts and mechanisms where the shaft does not have the necessary hardness or surface finish to roll directly on the needles. In Argentine industry, they appear in maintenance of production equipment, in the food sector, in metalworking and in process plants that need to reduce wear and prolong shaft life.

To select the IR ring, you must verify the shaft diameter and length, the type of load, the working revolutions and the available space. Mounting requires cleanliness, correct alignment and adequate lubrication: grease or oil depending on the operating conditions. If the shaft shows wear, it is advisable to evaluate the condition of the raceway before placing the ring, because any imperfection is transferred to the bearing.

Needle inner rings are available under different brands and nomenclatures. Interchangeability between manufacturers is not automatic: inner diameter, outer diameter, width, tolerances and raceway type must be compared. Therefore, even if the part number is similar, it is always advisable to validate the equivalence with a specialist before replacing a part.

If you have the ring part number or the shaft size, send it by WhatsApp to MR Accesorios Industriales and we will quote you promptly. We can also help you identify the INA series that corresponds to your equipment and resolve mounting or lubrication questions.
