Introduction to Ruland Shaft Collars

Shaft Collars are one of the simplest components in power transmission. They can be found in virtually any type of machinery and are frequently accessories to other components.  Among their many roles, shaft collars hold bearings and sprockets on shafts, situate components in motor and gearbox assemblies, and serve as mechanical stops.

Ruland shaft collars are offered in multiple styles to fit shafts ranging from 1/8" to 6" in the inch series and 3 mm to 150 mm in the metric series, in a variety of materials and finishes including 316 stainless steel, 303 stainless steel, black oxide or yellow zinc plated carbon steel, high-strength aluminum, and engineered plastic. Shaft 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 a shaft collar is used as a bearing face, a mechanical stop, or for mounting other components.
