Eliminate the weaknesses of keyed connections with the Z14 Expansion Sleeve. This high-performance mechanical component uses the principle of wedge mechanics to create a powerful, rigid interference fit between the shaft and the hub such as gears, sprockets, and pulleys.

How It Works: By tightening the high-strength bolts, the internal tapered rings expand radially, generating immense contact pressure. This pressure locks the shaft and hub together securely, allowing for the transmission of high torque and axial loads purely through friction.
