00717708-0021 Sullivan OEM Drive Coupler | Genuine High-Performance Compressor Coupling

The 00717708-0021 Sullivan-Palatek OEM Drive Coupler is an original equipment coupling designed specifically for use in Sullivan-Palatek rotary screw air compressor drive systems. This component connects the electric motor or engine to the compressor air-end, allowing rotational power to be transferred efficiently while isolating vibration and accommodating minor misalignment between shafts.

In rotary screw compressors, the drive coupler plays a critical role in maintaining alignment, protecting bearings, and ensuring smooth torque delivery. Excessive vibration or improper coupler performance can lead to premature bearing failure, seal wear, and reduced compressor efficiency. The 00717708-0021 coupler is engineered to prevent these issues by maintaining the precise elastomer stiffness, balance, and geometry required by Sullivan-Palatek equipment.

Unlike aftermarket or “OEM-style” alternatives, this is a true Sullivan-Palatek OEM part, manufactured to the same specifications as the coupler originally installed at the factory.

Key Features and Benefits

• Genuine Sullivan-Palatek OEM Coupler – Factory-specified part, not aftermarket or aftermarket-equivalent.

• Exact Fit and Balance – Designed for direct replacement with no modification required.

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

• 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 – Built for continuous-duty industrial compressor environments.

• OEM Reliability – Preserves original compressor performance and service life.

Functional Design and Performance

The 00717708-0021 Sullivan-Palatek drive coupler utilizes a resilient elastomer element bonded to precision-machined metal hubs. This configuration allows the coupler to act as a torsional buffer, absorbing vibration and load fluctuations before they are transmitted into the compressor drive train.

During startup, shutdown, and load changes, rotary screw compressors generate torsional shock that can place stress on shafts and bearings. The elastomer element within this OEM coupler absorbs those forces, helping maintain alignment and reducing mechanical noise.

Because this coupler is manufactured to Sullivan-Palatek’s exact specifications, the elastomer hardness and internal geometry are matched precisely to compressor operating characteristics. This ensures predictable damping behavior and long-term durability that generic replacements often cannot provide.

Applications and Compatibility

The 00717708-0021 Sullivan-Palatek OEM Drive Coupler is used in a range of Sullivan-Palatek compressed air systems, including:

• Rotary screw air compressors

• Stationary industrial compressor installations

• Engine-driven and electric-motor-driven units

• Compressor rebuilds and scheduled maintenance programs

This coupler is intended as a direct OEM replacement for the original factory-installed component. Using the correct OEM coupler helps maintain proper alignment, vibration control, and protection of critical compressor components.

Performance Advantages of Using OEM

Using the 00717708-0021 genuine Sullivan-Palatek OEM coupler ensures your compressor operates exactly as designed. Aftermarket couplers may appear similar but often differ in elastomer stiffness, balance, or dimensional tolerances, which can result in increased vibration, reduced efficiency, or premature air-end failure.

This OEM coupler delivers consistent performance under load, reduces stress on connected components, and helps extend the overall service life of the compressor. For mission-critical compressed air systems, genuine OEM parts are essential to maintaining uptime and reliability.
