128387-404 Quincy OEM Drive Coupler

The 128387-404 Quincy OEM Drive Coupler is a coupling for Quincy Compressor rotary screw air compressor platforms. This coupling connects the drive motor to the compressor airend through a torsionally flexible element that isolates vibration and transmits torque smoothly.

Quincy compressors serve industrial facilities, auto body shops, manufacturing plants, and continuous-duty process applications. In these environments, compressors accumulate high operating hours and the drive coupling gradually wears from sustained torsional load. The 128387-404 is engineered for the specific torque and vibration profile of its target Quincy models, ensuring proper damping characteristics throughout its service life.

The 128387-404 is a direct factory replacement. Follow Quincy’s service manual for coupler removal and installation, including alignment verification and torque specifications. Confirm normal vibration readings and stable compressor performance after installation.
