The NSK FIR series inner ring is a precision component used as the inner raceway in needle roller bearings. It is mounted on the shaft and provides a hard, ground surface on which the needles roll, which eliminates the need for heat treatment of the shaft and facilitates maintenance. It is a key part in applications requiring high radial load capacity and a compact design, such as transmissions, pumps and industrial machinery.

The FIR series designation consists of a fixed prefix and a numeric suffix that identifies the size. For example, the part number FIR-606825-1A indicates an inner ring with specific dimensions: the first digits usually reference the inner and outer diameters, while the following ones define the width. The -1A suffix indicates a design or tolerance variant. To select the correct ring, it is essential to know the dimensions of the shaft and of the needle roller bearing it will work with. If you have doubts, send us the complete part number and we will advise you.

These rings are used in a wide variety of industries in Argentina, such as automotive, metallurgical, food and agricultural machinery. They are found in gearboxes, hydraulic pumps, compressors, electric motors and power transmission equipment. Their function is to withstand high radial loads in tight spaces, which makes them ideal for applications where size and weight are critical. MR Accesorios Industriales sells this series to supply maintenance workshops and production plants.

For a correct selection, take into account the shaft diameter, ring length and required tolerance. Installation must be done carefully, ensuring precise alignment with the bearing and avoiding blows that could damage the ground surface. Adequate lubrication is essential: it is recommended to use the same lubricant as in the bearing and to verify that the ring is correctly seated. If the shaft shows wear, the inner ring can be a solution to restore the original size.

As for equivalents, NSK FIR series inner rings can be interchanged with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG or NTN, as long as the measurements and tolerances match. It is important to verify the complete part number and technical specifications before replacing a part. If you need assistance identifying the equivalent, contact us with the original part number and we will help you find the compatible option.
