MAV is one of the world leaders in the design, development, and manufacturing of keyless locking devices. We offer a vast range of internal and external locking assemblies, including shrink discs and rigid couplings.

MAV Locking Assemblies eliminate bothersome keys and keyways which are difficult to machine and to 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. 

Drive Elements like Pulleys, Gears, Conveyor Drums fitted with keys/keyways are difficult to remove, assemble, adjust 

Keyways and splines are eliminated by Locking Assemblies – a design using 2 tapers and frictional forces to hold the product & shaft together.

Specials  :    MAV specializes in Designing & offering Special Locking Assemblies, Shrink Discs – using their inhouse Design Engineers & Special Software

Also known as Clamping units and used as Keyless Bushes to mount products onto shafts, without keys and keyways.

MAV SpA of Italy has been in this competitive field for the past 30 years and is a major player in the US, Australian and European market. Manufactures high quality shaft-hub connections encompassing a range from 6 to 600mm (as a standard). Has built up unique expertise in designing and manufacturing clamping units to conform to individual requirements providing various types of coatings (for critical environment applications). MAV SpA was the first Italian Company get an ISO certification for manufacturing/marketing of Clamping Units, way back in 1998 itself.
