2657936395 Atlas Copco OEM Drive Coupler | High-Performance Compressor Coupling

The 2657936395 Atlas Copco OEM Drive Coupler is an original equipment flexible coupling designed specifically for use in Atlas Copco compressor drive systems. This component connects the electric motor to the compressor air-end, transmitting rotational power efficiently while isolating torsional vibration and compensating for minor shaft misalignment during normal operation.

In rotary screw air compressors, the drive coupler plays a critical role in drivetrain stability. Startup shock, load transitions, and continuous-duty operation generate torsional forces that can stress shafts, bearings, and air-end components. The 2657936395 coupler is manufactured to Atlas Copco’s OEM dimensional and material specifications to ensure correct alignment, stable torque transfer, and long-term reliability in industrial operating environments.

Designed for heavy-duty compressed air applications, this coupler supports consistent performance and protects high-value rotating components from premature wear.

Functional Design and Performance

The 2657936395 OEM drive coupler incorporates a resilient elastomer element bonded to precision-machined metal hubs. This configuration allows the coupler to function as a torsional isolation device, reducing the transmission of vibration and transient torque spikes throughout the compressor drivetrain.

During startup and shutdown cycles, compressors experience significant torsional shock loads. The elastomer element within the 2657936395 absorbs these forces, helping maintain alignment between the motor and air-end while reducing mechanical noise and protecting connected components.

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