INA needle roller bushings series IR serve as the inner raceway in needle roller bearing arrangements. They are built for high radial loads where radial space is tight, so they suit compact machine designs. MR Industrial Accessories supplies this series as part of its bearing line for customers in the United States and several Latin American countries.

The part number follows a simple pattern: the letters IR plus a number that gives the bore diameter in millimeters. IR12, for instance, has a 12 mm bore. Reading the code this way lets a maintenance or purchasing professional identify the needed size without extra lookup.

These bushings act as the inner raceway for needle roller bearings, so fit and alignment matter. Typical installations include machine tools, power transmission equipment, pumps, compressors and agricultural machinery. In each case, the bushing allows the bearing assembly to handle radial loads within a small cross section.

Selection depends on shaft diameter, radial load and lubrication conditions. The shaft surface should be hardened and ground. Proper lubrication and accurate alignment help avoid premature wear. Also confirm that the bushing matches the needle roller bearing it will run with, so the fit is correct.

INA needle roller bushings series IR may interchange with other brands that use the same designation and dimensions, but tolerances and load capacity should be checked before substituting. MR can suggest equivalents and help you choose the right option for the application.
