Shaft Collars

Ruland shaft collars are offered in multiple styles to fit shafts ranging from 1/8" to 6" in the inch series and 3mm to 80mm in the metric series, in a variety of materials and finishes. Collars are stamped with the Ruland name and the bore size for easy identification. Extra steps are taken in the manufacturing of Ruland's shaft collars to provide important performance benefits. For example, Ruland collars are single point faced (indicated by the circular groove on the face) during the boring operation to insure perpendicularity of the face to the bore. Perpendicularity is important for alignment when shaft collars are used as a bearing face, a mechanical stop, or for mounting other components.
