Lutco unground radial ball bearings are designed for applications where speeds and loads are moderate and where noise level requirements and running accuracy do not justify using more expensive precision ground bearings. Since the raceways are unground, maximum recommended speed is 1200 rpm.
Radial bearings consist of a full complement of precision steel balls, a machined inner race and a pair of cold formed outer races captured by a soft steel band. The soft steel band on the OD allows for the bearing to be pressed into a housing made without close housing tolerances.
