Secure your rotating components with the Z7 Expansion Sleeve. This mechanical transmission component is designed to create a rigid, maintenance-free connection between a shaft and a hub such as a gear, sprocket, or flywheel.

How It Works: The Z7 utilizes the principle of wedge mechanics. By tightening the high-strength locking bolts, the inner and outer tapered rings are pressed together, generating massive radial pressure. This creates a secure friction interference fit that locks the shaft and hub together as a single unit.
