High Torque Keyless Locking Assembly

Z12C high‑torque keyless Locking Assembly produced by Hebei Fenna Transmission Machinery Co., Ltd., is a stable shaft‑hub keyless locking component. It can be matched with Serpentine Spring Coupling, Roller Chain Coupling, Coupling, Backstop and other transmission assemblies, widely applied for Driving Drum, conveyor equipment, hoisting machinery, mining equipment and other working conditions. Locking Assemblies generate uniform radial clamping force by tightening high‑strength bolts, transmitting torque and axial load by friction. No keyway machining is required, which protects the original structure of shafts and hubs. Forged from high‑quality alloy steel with complete heat‑treatment process, this Locking Assembly owns high strength and excellent fatigue resistance to bear alternating impact loads. It features good concentricity and high centering accuracy. Hot‑mounting or press‑fitting tools are not required for installation. Tighten bolts to specified torque to finish assembly,…
