IKO Bearing IRT5212 Inner Ring, Metric, 52 mm Inside Diameter, 62 mm Outside Diameter, 12.5 mm Width, For Shell Type, High Carbon Steel, To Assemble with TA6212Z

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. 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 mm. Without oil hole.
