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. They’re an economical alternative to bushings because they don’t 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.
