02250152-674 Sullair OEM Coupling Kit

The 02250152-674 / 02250152-681 Sullair OEM Coupling Kit is a complete drive coupling assembly for Sullair stationary rotary screw compressors. Drive couplings transmit torque from the motor to the airend while accommodating slight shaft misalignment and damping torsional vibration. When the elastomer element wears, hardens, or develops cracks, the compressor loses efficiency and risks damage to adjacent driveline components.

This kit includes:

02250152-674 Sullair OEM Coupling Element (the flexible elastomer drive component)
02250152-681 Sullair OEM Coupling Cover (the matching cover assembly)
Mounting screws for bolting the cover to the element

Bundling all three components into a single order means you can complete a scheduled coupling service in one shipment instead of waiting on separate parts. Replacing the cover and hardware along with the element is the OEM-recommended approach during major service intervals – the cover and bolts can fatigue over the same duty cycle as the element itself, and replacing them together restores the full assembly to OEM spec.

Known applications:

Sullair TS32 Rotary Screw Compressor
Sullair V320TS Rotary Screw Compressor

The 02250152-674 element provides flexible torque transmission with vibration damping, while the 02250152-681 cover contains the element and provides the bolt-down interface to the driveline housing. Both parts are direct OEM replacements and meet original Sullair specifications for fit and performance.

During installation, follow the Sullair service manual for the correct bolt torque sequence and final assembly checks. Inspect the existing element for the failure mode (hardening, surface cracking, edge wear, or delamination) to identify whether duty cycle, contamination, or operating temperature is shortening service life. Inspect adjacent components – motor shaft, airend input shaft, alignment, and bearings – for related wear that may have contributed to the coupling failure.
