Streamline your mechanical assemblies with the Z11 Expansion Sleeve. It uses a mechanical interference fit to lock components such as gears, sprockets, timing pulleys, and conveyor drums to a shaft without the need for keyways.

How It Works: The Z11 series consists of an inner ring, an outer ring, and a set of locking screws. Tightening the screws drives the tapered rings together, creating immense radial pressure. This pressure generates a secure, friction-based bond that transmits high torque and axial loads while automatically centering the hub on the shaft.
