High Torque Compact Locking Assembly

Z13 compact keyless Locking Assembly manufactured by Hebei Fenna Transmission Machinery Co., Ltd., is a lightweight compact keyless shaft‑hub locking element. It can be matched with Serpentine Spring Coupling, Roller Chain Coupling, Coupling, Backstop and other transmission parts, widely used in light‑medium torque transmission scenarios such as Driving Drum, packaging machinery, textile machines and small‑size conveying equipment. Locking Assemblies produce uniform radial pressure by tightening high‑strength bolts, transmitting torque and axial force purely through friction. No keyway is needed and it will not damage the base of shafts and hubs. Precision‑forged from high‑quality alloy steel and strengthened by heat treatment, this Locking Assembly features small size and compact structure to realize reliable locking within limited installation space, with high centering accuracy and stable re‑positioning performance. Installation is simple without hot‑mounting or press‑fitting eq…
