The SKF inner ring of the LR series is a removable raceway that is mounted on the shaft to support the needles of a needle roller bearing. It is used when the shaft does not have the hardness or surface finish required to serve directly as a raceway. MR Accesorios Industriales carries this line as part of its SKF bearing offering.

The LR series designation is read as a set of dimensions: the first two numbers indicate the bore diameter, the second pair the outside diameter and the last the width. For example, LR 15X18X12.5 corresponds to a ring with a 15 mm bore diameter, 18 mm outside diameter and 12.5 mm width. Any suffixes that may appear after the series add design characteristics, such as the type of machining or surface treatment, and they should be verified against the technical data sheet before defining the replacement.

These rings are used in applications where the shaft is not hardened or does not have the proper roughness to function as a direct raceway. They are common in agricultural machinery, transmission equipment, pumps, compressors, machine tools and conveying systems. In Argentina, the metalworking, food and industrial maintenance sectors turn to this solution to repair or modify assemblies without having to replace the entire shaft.

To select the correct ring, take into account the shaft diameter, the bearing width and the type of load. The raceway must have the proper hardness and finish; that is why SKF rings come with heat treatment and precision grinding. During mounting, verify alignment with the bearing and avoid impacts that could damage the raceway surface. Lubrication must be compatible with that of the assembly and renewed according to the maintenance plan.

LR series inner rings are interchangeable between brands in terms of standardized dimensions, but they may vary in tolerances, hardness and surface finish. When replacing, always compare the dimensions and service conditions.
