6.4578E3 Kaeser Coupling

The 6.4578E3 Kaeser Drive Coupler is an OEM replacement coupling for Kaeser rotary screw air compressors and related industrial rotating equipment. The coupler connects the motor output shaft to the airend input shaft, transmitting full operational torque while compensating for the angular and parallel shaft misalignment that occurs during normal operation, thermal expansion, and machine settling.

Kaeser couplings are engineered for continuous-duty industrial service and selected as the factory drive component on a wide range of compressor packages, pumps, generator sets, and power transmission assemblies. Proper coupler condition protects the motor bearings, airend bearings, and shaft seals from premature wear caused by misalignment loads and torque irregularities passing through the drivetrain.

Inspect the coupler during routine compressor maintenance and replace at the first sign of wear, deformation, or loss of fit between mating surfaces. Built to Kaeser OEM specifications. Available from Stark Industrial Products with same-day shipping on in-stock orders and 24/7 phone support at (903) 768-1111.
