IKO LRT607040 LRT - Series

Inner Rings can be integrated with shell type or various machined Needle Roller Bearings to provide good roller support without worrying about premature shaft wear. We heat-treat and grind our Inner Rings to tight tolerances to create hard, tough raceways for applications where it is impossible to make shaft surfaces to a specific hardness or roughness attribute. Theyre an economical alternative to bushings because they dont require any additional machining. Wide Inner Rings are also available to accommodate shafts that move axially or seals that are adjacent to bearings. Inner rings come in a broad range of shaft diameters and assembly elements include small chamfers or gentle taper relief options. Inner rings for machined type Needle Roller Bearings come in a variety of dimensions. Metric type LRT series Inner Rings have shaft diameters from 5 to 440 mm. Inch type LRB series Inner Rings offer shaft diameters from 3/8 to 3-3/4 in and oil hole versions for easier lubrication.
