Bearing Inner Rings

Precision ground inner ring provides a hardened raceway for the rollers when used with an unhardened shaft. The ring contains an oil hole and annular groove for relubrication of the bearing and can be used with both CAGEROL® and GUIDEROL® bearings or can be utilized as a bushing in plain bearing applications.

Where it becomes impractical to meet the shaft raceway design requirements (hardness, case depth, surface finish, etc.) outlined in the engineering section, standard inner rings for drawn cup bearings are available. Inner rings for drawn cup bearings are designed to be a loose transition fit on the shaft and should be clamped against a shoulder. If a tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring OD as mounted, must not exceed the raceway diameters required by the drawn cup bearing for the particular application.

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. 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.
