The 02250046-555 Sullair OEM Drive Coupler Kit is an original equipment drivetrain assembly engineered for use in Sullair compressor drive systems. This kit includes both the torsionally flexible elastomer coupling element and the corresponding outer flange, providing a complete coupling solution designed for proper installation and alignment.
In rotary screw air compressors, the drive coupler connects the electric motor to the air-end, transmitting torque while absorbing torsional shock and compensating for minor shaft misalignment. Continuous-duty compressor operation generates startup loads, vibration, and fluctuating torque conditions that place stress on drivetrain components. The 02250046-555 kit is manufactured to Sullair’s OEM dimensional and material standards to ensure stable torque transfer and predictable damping characteristics.
Supplying the coupling element and outer flange together ensures correct component pairing and reliable performance under load.

Functional Design and Performance
The elastomer element within the 02250046-555 coupler kit functions as a torsional isolation device. Torque is transmitted through compression of the elastomer, reducing direct metal-to-metal force transfer and minimizing vibration transmission.
During startup and load transitions, compressors experience peak torque spikes that can accelerate bearing and shaft wear. The flexible element absorbs these forces, helping maintain alignment and reducing mechanical stress on connected components.
The included outer flange ensures proper mechanical integration into the drive system, supporting balanced rotation and secure mounting. Because this is a genuine Sullair OEM assembly, the elastomer compound and flange geometry are engineered specifically for Sullair compressor operating characteristics.
