128387-406Quincy Drive Coupler

Description

The 128387-406 Quincy Drive Coupler is an OEM coupler for portable and stationary air compressor drive systems. It connects the driving and driven shafts, transmitting torque while absorbing the torsional vibration and shock load that occur at startup and under changing load.

Drive couplings are wear items. Once the element hardens or cracks, vibration and misalignment pass straight through to the bearings, shafts, and seals around it. This is the factory component, dimensioned to fit the original mounting without modification.
