02250046-555 Sullair OEM Drive Coupler | Heavy-Duty Flexible Compressor Coupling

The 02250046-555 Sullair OEM Drive Coupler is a precision-manufactured flexible coupling designed specifically for use in Sullair rotary screw air compressor drive systems. This coupler connects the motor to the air-end, allowing rotational power to be transmitted efficiently while absorbing vibration and compensating for minor shaft misalignment.

In rotary screw compressors, consistent torque transfer and vibration control are essential for maintaining air-end alignment, bearing life, and overall compressor efficiency. The 02250046-555 coupler plays a critical role in protecting the drive system from torsional shock generated during startup, shutdown, and load changes.

Built for continuous-duty compressor operation, this OEM coupler delivers dependable performance in demanding industrial environments.

Key Features and Benefits

• Genuine Sullair OEM Drive Coupler – Manufactured to Sullair engineering and performance specifications.

• Flexible Elastomeric Design – Absorbs torsional vibration and dampens shock loads.

• Smooth Torque Transmission – Provides stable, backlash-free power transfer between motor and air-end.

• Misalignment Compensation – Accommodates angular, axial, and parallel shaft misalignment.

• Heavy-Duty Construction – Designed for continuous-duty rotary screw compressor applications.

• Protective Drive System Function – Helps safeguard motors, air-ends, and bearings from overload stress.

• Low Maintenance Operation – Lubrication-free design supports long service intervals.

Functional Design and Performance

The 02250046-555 Sullair Coupler utilizes a resilient elastomer element bonded to precision-machined metal hubs to form a torsionally flexible connection between the motor shaft and compressor air-end. This design allows the coupling to act as a mechanical buffer, absorbing vibration and load fluctuations before they can be transmitted into sensitive components.

In compressor applications, torsional vibration is a leading cause of bearing wear, shaft fatigue, and air-end misalignment. The elastomer element within the 02250046-555 coupling reduces these forces, improving system stability and extending the service life of the compressor drive train.

The coupling also compensates for minor installation tolerances and thermal expansion that naturally occur during compressor operation, helping maintain proper alignment over time.

Applications and Compatibility

The 02250046-555 Sullair OEM Drive Coupler is commonly used in:

• Sullair rotary screw air compressors

• Industrial compressed air systems

• Stationary and portable compressor units

• Compressor rebuilds and scheduled maintenance programs

This coupler is intended as a direct replacement for original Sullair drive couplers specified in compatible compressor models, ensuring proper fitment, balance, and vibration damping.
