The 250014-698 Sullair Drive Coupler Kit is a complete OEM coupling assembly for Sullair rotary screw compressors and related industrial drive applications. The kit ships with the center hub, four (4) drive pins, and four (4) mounting bolts, supplying every component needed for a full coupling refresh during scheduled maintenance.
The coupler connects the motor or engine output shaft to the driven component, transmitting full operational torque while compensating for the angular and parallel shaft misalignment that develops during normal running. Sullair drive couplings of this design serve across portable air compressors, stationary industrial compressor packages, hydraulic power units, and similar rotating equipment where reliable torque transmission and minimal driveline backlash are required.
Replace the complete assembly when wear is detected on any single component to restore the drivetrain to OEM specification rather than mixing new and worn parts. Built to Sullair OEM specifications. Available from Stark Industrial Products with same-day shipping on in-stock orders and 24/7 phone support at (903) 768-1111 to confirm fitment before you order.
