Ruland manufactures shaft collars in multiple styles to fit shafts ranging 1/8" to 6" in the inch series and 3mm to 150mm in the metric series. Ruland shaft collars are available in a variety of materials and finishes including: 303 & 316 stainless steel, black oxide and yellow zinc plated carbon steel, high-strength aluminum, and engineered plastic.

MAV Shrink Discs or external locking devices, which provide a rigid, zero-backlash frictional connection between hollow shafts (hub) and shafts.

These elements offer extremely concentric and well balanced connections, ideal for high speed applications. Presented in 3 options – Heavy, medium and light, depending upon torque transmissions. Also available in SPLIT version,

MAV Locking Assemblies eliminate bothersome keys and keyways which are difficult to machine and maintain tight tolerances. Keyways and splined locking systems have important disadvantages, particularly under overload and frequent torque reversals. The notch of the keyway seat is a stress concentrator which increases fatigue strength. Keyways and splines are eliminated by Locking Assemblies a design using 2 tapers and frictional forces to hold the product & shaft together.Also known as Clamping units and used as Keyless Bushes to mount products onto shafts, without keys and keyways.
