Heavy‑Duty Keyless Z12A Locking Assembly

Z12A heavy‑duty keyless Locking Assembly offered by Hebei Fenna Transmission Machinery Co., Ltd., is a keyless shaft‑hub connection component for high‑load working conditions. It can be matched with Serpentine Spring Coupling, Roller Chain Coupling, Coupling, Backstop and other transmission parts, widely applied for Driving Drum as well as large‑scale conveying, mining and metallurgical equipment. Locking Assemblies generate uniform radial clamping force by tightening high‑strength bolts, transmitting large torque and combined loads purely through friction. No keyway processing is required and it will not damage the base of shafts and hubs. Manufactured from high‑grade alloy steel by integral forging and quenching‑and‑tempering heat treatment, this Locking Assembly features high strength and strong deformation‑resistance to bear heavy radial and axial combined loads. It delivers outstanding centering accuracy and simple assembly‑disassembly. Thermal mounting or press‑fitting is not…
