1622311055-1622311056 Drive Gear Wheel Set For Rotary Screw Air Compressor

Product Introduction

1622311055 and 1622311056 are a matched drive gear wheel pair used in the gearbox end of rotary screw air compressors, listed for GA75-class machines in supplier references. They transmit motor torque to the rotor shaft at the correct centre distance and tooth mesh, so runout, tooth wear, or incorrect pairing quickly shows up as noise, vibration, and bearing load. Treat them as a set—never mix one gear with a different-hardness or different-profile mate. Machining, heat treatment, and bore fit need checking against the old gears before install; also called gear wheel set, drive gear pair, transmission gear.
