128387-406 Quincy OEM Drive Coupler

The 128387-406 Quincy OEM Drive Coupler is an OEM coupling for Quincy Compressor rotary screw air compressor systems. Quincy manufactures stationary compressors for industrial manufacturing, automotive service, and continuous-duty process applications.

Quincy compressors are built for long service life in demanding industrial environments. The drive coupler connects the motor to the airend, absorbing torsional vibration that would otherwise accelerate bearing and seal wear. In facilities where Quincy compressors run around the clock, coupler maintenance is an essential part of keeping the machines reliable and efficient.

The 128387-406 is a direct factory replacement. During installation, verify motor-to-airend alignment per Quincy’s specifications. Confirm smooth operation and acceptable vibration levels after startup.
