Precision Keyless Locking Assembly Bushing

Precision keyless locking assembly, namely Locking Assembly, developed and manufactured by Hebei Fenna Transmission Machinery Co., Ltd., is a high‑performance keyless shaft‑hub connection component. It perfectly matches various transmission parts such as Serpentine Spring Coupling, Roller Chain Coupling, Coupling, Backstop, and is widely applied for shaft‑hub connection of Driving Drum and other main machinery equipment. Locking Assemblies generate radial compression force by tightening high‑strength bolts to stably transmit torque and combined axial load without flat keys. Made of high‑quality alloy steel with quenching‑tempering and precision grinding, this product delivers high dimensional accuracy and stable performance after repeated disassembly and assembly. No heating or press‑fitting is required for installation. It can be assembled simply by tightening bolts to specified torque. It allows looser machining tolerances for shafts and hubs, greatly cutting manufacturing and as…
