Expansion Coupling Sleeve Main Advantages

  • Easy to install

    Low machining accuracy required for shaft holes, no need for heating/pressurising equipment, only need to tighten bolts diagonally according to torque.

    Allows hubs to be repositioned on the shaft and supports couplings with poorly welded materials.

  • High reliability

    No keyway weakening structure, no relative motion wear, long life.

    Automatic failure in case of overload protects equipment safety.

  • Flexible adaptation

    can withstand multiple loads, support the use of multiple expansion sleeves in series to increase the load.

    Easy to disassemble (just loosen the bolts), anti-rust design of the contact surface to ensure repeated use.
