22351720 Ingersoll Rand OEM Drive Coupler | Compressor Motor-to-Air-End Coupling

The 22351720 Ingersoll Rand OEM Drive Coupler is an original equipment flexible coupling designed for use in Ingersoll Rand compressor drive systems. This component connects the electric motor to the compressor air-end, allowing efficient transmission of rotational power while isolating vibration and absorbing torsional shock generated during operation.

In rotary screw compressor applications, drivetrain components are subjected to startup loads, fluctuating torque conditions, and continuous duty cycles. Without proper torsional flexibility, these forces can accelerate wear on shafts, bearings, and air-end assemblies. The 22351720 coupler is manufactured to Ingersoll Rand’s OEM engineering specifications to ensure correct dimensional tolerances, elastomer performance, and balanced rotation.

Designed for industrial environments, this coupler supports compressor efficiency and helps protect critical rotating components from premature failure.

Functional Design and Performance

The 22351720 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 within the compressor drivetrain.

During startup and shutdown cycles, rotary screw compressors generate torsional forces that can stress connected components. The elastomer element within the 22351720 absorbs these loads, helping maintain alignment between the motor and air-end while reducing mechanical noise and protecting drivetrain components.

Because this is a genuine OEM Ingersoll Rand component, the elastomer compound and hub geometry are engineered specifically for Ingersoll Rand compressor operating characteristics. This ensures predictable damping behavior, consistent torque delivery, and long-term reliability in continuous-duty industrial environments.
