Shaft collars hold tight face tolerance

Shaft collars from Ruland are single-point faced to ensure a high level of face-to-bore perpendicularity. The result is face runout of TIR <0.05mm (0.002-in.) on standard collars with even tighter tolerance on bearing locknuts and special designs.

Ruland offers shaft collars in aluminum, black oxide carbon steel and stainless steel, as well as engineered plastic collars. One- and two-piece clamp-style designs are available with bore sizes from 3mm to 80mm (0.125-in. to 6.0-in.). Clamp-style shaft collars do not mar the shaft like traditional set-screw types. Clamp- style collars also have higher holding power because they wrap around the shaft when tightened thus applying compressive stress nearly uniformly on the circumference of the shaft.

Two-piece, clamp-style collars have an additional advantage since they can be installed on the shaft without removing other components. Ruland uses forged socket hardware in all its shaft collars, which allows for higher screw torque and increased holding power.

Shaft collars are widely used components in the power transmission industry. They function as mechanical stops, clamps often used on split hubs, bearing faces and as a means for locating components on a variety of equipment.
