The 1626-5109-00 Atlas Copco OEM Drive Coupler is an original equipment flexible coupling designed for use in Atlas Copco compressor drive assemblies. 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 air compressor systems, drivetrain components operate under startup shock, fluctuating torque loads, and continuous-duty cycles. Without proper torsional flexibility, these forces can accelerate wear on shafts, bearings, and air-end assemblies. The 1626-5109-00 coupler is manufactured to Atlas Copco’s OEM dimensional and material specifications to ensure precise alignment, balanced rotation, and predictable damping performance.
Designed for demanding industrial environments, this coupler supports compressor reliability and protects high-value rotating components from premature failure.

Functional Design and Performance
The 1626-5109-00 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 shock loads that can stress connected components. The flexible element within the 1626-5109-00 absorbs these forces, helping maintain alignment between the motor and air-end while reducing mechanical noise and drivetrain stress.
Because this is a genuine OEM Atlas Copco component, the elastomer compound and hub geometry are engineered specifically for Atlas Copco compressor operating characteristics. This ensures consistent torque delivery, predictable vibration damping, and reliable service life under continuous-duty industrial conditions.
