02250146-634 Sullair OEM Drive Coupler | Compressor Motor-to-Air-End Coupling

The 02250146-634 Sullair OEM Drive Coupler is an original equipment flexible coupling designed for use in Sullair compressor drive systems. This component connects the electric motor to the compressor air-end, efficiently transmitting rotational power while absorbing torsional shock and compensating for minor shaft misalignment during operation.

In rotary screw compressor applications, drivetrain components are subjected to startup shock, fluctuating torque conditions, and continuous-duty cycles. Without proper torsional flexibility, these forces can accelerate wear on shafts, bearings, and air-end assemblies. The 02250146-634 coupler is manufactured to Sullair’s OEM dimensional and material specifications to ensure proper alignment, predictable damping characteristics, and long-term durability in demanding industrial environments.

Designed for continuous-duty operation, this coupler supports compressor reliability and helps protect high-value rotating components from premature failure.

Functional Design and Performance

The 02250146-634 OEM drive coupler incorporates a resilient elastomer element bonded to precision-machined metal hubs. This configuration allows the coupling to function as a torsional isolation device, reducing vibration transfer and minimizing peak torque spikes throughout the compressor drivetrain.

During startup and shutdown cycles, compressors generate torsional forces that can stress connected components. The elastomer element within the 02250146-634 absorbs these loads, helping maintain alignment between the motor and air-end while reducing mechanical noise and drivetrain stress.

Because this is a genuine OEM Sullair component, the elastomer compound and hub geometry are engineered specifically for Sullair compressor operating characteristics. This ensures consistent torque delivery, predictable vibration damping, and reliable service life under continuous-duty industrial conditions.
