5 mm to 8 mm Plum Blossom Flexible Coupling with Elastomer Insert

This plum blossom flexible shaft coupling is designed to transmit motion between a motor and a driven shaft while using an elastomer insert to absorb vibration and compensate for minor shaft misalignment without compromising transmission stability.

Unlike helical beam couplings, this design incorporates a flexible elastomer spider between two aluminium hubs. The elastomer helps damp shocks, reduce vibration and protect motors, bearings and lead screws from unnecessary mechanical stress. It is particularly suitable for low-torque applications and installations with limited space.
