Sullivan Palatek Drive Coupler Guide
Sullivan Palatek is widely recognized as one of the most dependable names in American industrial air compressors, producing heavy-duty rotary screw units designed for construction, manufacturing, utilities, and demanding plant environments. Their compressors are engineered for durability, serviceability, and high performance, and a properly matched drive coupler is essential to keeping these machines running at full efficiency. At Stark Industrial Products, we supply the correct Sullivan-Palatek couplers that maintain the smooth operation, torque transfer, and vibration control their systems rely on every day.
Sullivan-Palatek compressors operate under continuous load conditions and often run in abrasive, high-vibration, and temperature-sensitive environments. The drive coupler serves as the mechanical link between the motor and the screw airend, transmitting power while absorbing misalignment and mechanical shock. When the coupler begins to degrade, you can experience elevated vibration, heat buildup, bearing wear, or catastrophic airend damage. As the leading supplier of compressor couplers in the United States, Stark Industrial Products helps operators avoid failures by providing correctly matched components with fast fulfillment and expert support.
Why Sullivan Palatek Compressors Depend on the Correct Coupler
Rotary screw compressors place high demands on the coupling system. The drive coupler must keep the motor and airend synchronized while compensating for the slight misalignment that naturally occurs during operation. In Sullivan-Palatek’s portable and stationary units, the coupler must also absorb pulsation, reduce harmonic vibration, and protect the drive train from shock loading. When the wrong coupler is installed—or an existing one is worn—the entire machine becomes vulnerable to imbalance, overheating, and premature component failure.
Many Sullivan-Palatek systems use rubber-insert or jaw-style couplers designed specifically for their horsepower range and airend geometry. Others require more rigid designs depending on the model and application. Stark Industrial Products maintains reliable inventory and supports customers with the knowledge required to select the right coupler the first time. Our focus is ensuring compressor operators nationwide maintain full system performance with dependable, factory-spec components.
How to Identify the Correct Sullivan Palatek Drive Coupler
The most accurate way to identify the required coupler is by referencing the compressor’s model and serial number or the markings on the existing coupling hub or insert. If this information is unavailable, measuring the hub diameter, thickness, keyway size, bolt-hole spacing, and element style will allow our team to determine the correct part. Even small differences in hub geometry can affect alignment, airflow, and bearing life.
For fast and accurate identification, customers often send us photos of the existing coupler or the compressor’s nameplate. Stark Industrial Products assists operators daily by matching the correct components quickly and confidently.

Common Causes of Coupler Wear in Sullivan Palatek Systems
Because these compressors are built for rugged environments, the coupler naturally absorbs a significant amount of mechanical stress. Over time, factors such as misalignment, mounting shifts, high ambient temperatures, pulsation, or deteriorated rubber elements can lead to cracks, deformities, or unusual vibration. If left unaddressed, this can cause motor strain, airend imbalance, or progressive drivetrain damage.
A failing coupler should always be replaced promptly. Stark Industrial Products ensures operators receive the correct replacement to restore the compressor’s smooth operation and protect the investment in both the motor and airend.
