Pin & Bush Coupling

Pin & bush couplings are designed for stable torque transmission in medium- and low-speed drive systems such as conveyors, reducers, and general industrial equipment. The coupling uses elastic pins to transmit torque while absorbing vibration, reducing noise, and compensating for limited shaft misalignment.

Made from high-quality steel, the coupling offers a reliable structure, smooth transmission. The coupling’s simple installation and convenient maintenance makes it well-suited for dusty, humid, and general industrial environments where a cost-effective and dependable shaft connection is required.

Working Principle
  • Torque is transmitted from the driving flange to the driven flange through a series of elastic pins.
  • As the pins undergo controlled shear and compression deformation during operation, the coupling effectively transmits power while absorbing vibration, reducing shock loads, and accommodating limited shaft misalignment.
Basic Data
  • Torque Transmission
  • Nominal torque range: 16–16000 N·m
  • Misalignment Compensation
  • The pin & bush coupling offers a lower compensation range than jaw and grid couplings
    1. Radial compensation: 0.5–2 mm
    2. Angular compensation: 0.5°–1°
    3. Axial compensation: ±1–5 mm
  • Vibration Damping & Cushioning:
  • Nylon pins absorb vibration and help reduce operating noise. Under overload conditions, the pins can shear to help protect connected equipment.
