Strong radial clamping force will be generated once high‑strength bolts are tightened, so this Locking Assembly can reliably transmit torque and axial loads. It is perfectly suitable for installation of Driving Drum, Backstop and all kinds of Coupling. Two structural versions‑A and B‑are available for this series of Locking Assemblies, with a wide selection of inner bore sizes. The locking connection will never weaken the structural strength of shafts or hubs. It features simple assembly & disassembly, outstanding part interchangeability and stable performance under shock‑loaded and frequent‑reversal working conditions. No heating or…
