Chromium Steel Inner Ring for Shell Type Needle Roller Bearings IRT3020 IRT404520
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.
IRT Series Inner Rings for Shell-Type Needle Roller Bearings
These rings are designed to provide a durable surface for shell-type needle roller bearings with non-machined raceways. Metric type IRT Series inner rings are available with shaft diameters from 7 to 60 millimeters.
