02250069-601 Sullair OEM Drive Coupler | Heavy-Duty Flexible Compressor Coupling

The 02250069-601 Sullair OEM Drive Coupler is a precision-manufactured elastomeric coupling designed specifically for use in Sullair rotary screw air compressor drive systems. This coupler connects the motor shaft to the compressor air-end, allowing rotational power to be transmitted efficiently while absorbing vibration and compensating for minor shaft misalignment.

In rotary screw compressors, the drive coupling plays a critical role in maintaining proper alignment between the motor and air-end. Excessive vibration or misalignment can lead to bearing wear, seal damage, and reduced compressor efficiency. The 02250069-601 coupler is engineered to minimize these issues, helping maintain stable operation and extend the service life of the compressor.

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

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 during startup and operation.

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

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

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

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

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

Functional Design and Performance

The 02250069-601 Sullair Coupler utilizes a resilient elastomer element bonded to precision-machined metal hubs to form a torsionally flexible connection between the motor and compressor air-end. This configuration allows the coupling to act as a mechanical buffer, absorbing vibration and load fluctuations before they can be transmitted into sensitive drive components.

During compressor startup, shutdown, and load changes, torsional shock can place excessive stress on shafts and bearings. The elastomer element within the 02250069-601 coupling reduces these forces, helping maintain alignment and reduce mechanical noise.

The coupler also compensates for minor installation tolerances and thermal expansion that naturally occur during compressor operation, ensuring consistent performance over time.

Applications and Compatibility

The 02250069-601 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.
