Extra Heavy‑Duty Keyless Locking Assembly

Z12B extra heavy‑duty keyless Locking Assembly manufactured by Hebei Fenna Transmission Machinery Co., Ltd., is a high‑torque heavy‑load shaft‑hub locking component. It can be combined with Serpentine Spring Coupling, Roller Chain Coupling, Coupling, Backstop and other transmission accessories, widely used in high‑load conditions such as Driving Drum, mining equipment, large conveyors and metallurgical machinery. Locking Assemblies generate huge and uniform radial pressure by tightening multiple high‑strength bolts, transmitting extra‑large torque purely by friction. Keyways are not required, and it will not weaken the strength of shafts and hubs. Forged from high‑quality alloy steel with deep quenching‑and‑tempering heat treatment, this Locking Assembly features high overall rigidity, excellent impact‑resistance and deformation‑resistance to withstand heavy combined radial and axial loads. It achieves high centering accuracy. No hot mounting or press‑fitting is needed for installa…
