Main series

NSK FIR Series Inner Ring

The NSK inner ring of the FIR series is a precision component that is mounted on the shaft to act as a raceway in needle roller bearings. It is used when the shaft is not hardened or ground and a hard surface with the appropriate roughness is needed for correct bearing operation. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and advises you on choosing the code that corresponds to your application.

The NSK IR 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 for the rollers, enabling compact arrangements with high load capacity. It is a key part when the shaft does not have the hardness or finish suitable to act directly as a raceway.
