Compact‑Type Precision Keyless Locking Unit

Compact‑Type Precision Keyless Locking Unit is carefully manufactured by Hebei Fenna Transmission Machinery Co., Ltd. As a small‑sized precision locking fitting, it can be assembled with Serpentine Spring Coupling and Roller Chain Coupling to build high‑precision transmission systems. Powerful radial friction generated by tightened bolts achieves keyless locking between shaft and hub for stable torque transmission. It is well‑suited for installation of mini‑sized Driving Drum, Backstop and all kinds of precision Coupling. This Locking Assembly, one of compact‑size Locking Assemblies, has bore diameters from 10 mm to 50 mm. Its small footprint greatly saves installation space of your machinery. The keyless connection will not weaken shaft‑hub strength, with easy disassembly and excellent interchangeability, making it ideal for precision automation equipment and light‑duty conveyors. No heating or press‑fitting is required for installation, and hub position can be adjusted freely on…
