1623357100 BoWex 80 Flexible Coupling Drive Hub Set for Rotary Screw Air Compressor

Product Introduction

Transmits motor torque to the airend while soaking up shaft misalignment. 1623357100 is listed as a BoWex 80 series curved-tooth coupling component for screw compressor drivelines. Steel hubs with a polyamide tooth sleeve give positive torque transmission and absorb parallel, radial, and angular offset that would otherwise beat up bearings and seals. On screw packages this is the buffer between motor pulsation and the rotor shaft—when the sleeve wears, cracks, or seizes on the hub, vibration climbs before anything else fails.

Match the BoWex 80 build, not just the stamping. Confirm hub bore, keyway, setscrew position, sleeve type, and assembled length E against the removed coupling. Bowex 80 covers several bore combinations, so shaft diameter and motor-to-compressor gap decide the correct set. Replace hubs and sleeve together when worn; mixing an old hub with a new sleeve hides the real backlash.

Also called BoWex 80 coupling, curved-tooth gear coupling, flexible drive coupling, compressor coupling hub set.
