46661941 Doosan OEM Drive Coupler | Genuine Compressor Coupling

The 46661941 Drive Coupler is an original equipment flexible coupling designed for use in engine-driven compressor systems manufactured under the Doosan, Bobcat, and Ingersoll Rand equipment lines. This component connects the diesel engine to the compressor air-end, transmitting rotational power efficiently while isolating torsional vibration and accommodating minor shaft misalignment during operation.

Portable and industrial compressor systems operate under demanding conditions that include fluctuating loads, continuous-duty cycles, and startup shock loads. Without a properly engineered coupling, these forces can transfer directly to drivetrain components such as bearings, shafts, and compressor air-ends. The 46661941 coupler is manufactured to OEM dimensional and material standards to ensure proper alignment, stable torque transmission, and predictable vibration damping.

Designed for rugged field environments, this coupler supports compressor performance and helps extend the service life of critical rotating components.

Functional Design and Performance

The 46661941 OEM coupler incorporates a resilient elastomer element integrated between precision-machined metal components. This design allows the coupling to act as a torsional isolation device, reducing vibration transfer and minimizing peak torque spikes throughout the compressor drivetrain.

Engine-driven compressors frequently experience torsional shock loads during startup and load transitions. The flexible element within the 46661941 absorbs these forces, helping maintain proper alignment between the engine and compressor air-end while reducing mechanical noise and drivetrain stress.

Because this component is manufactured to OEM equipment specifications, the elastomer compound and hub geometry are engineered to match the operational characteristics of these compressor systems. This ensures predictable damping behavior, reliable torque delivery, and consistent performance in continuous-duty industrial environments.

Why Use an OEM Drive Coupler

Using the 46661941 OEM drive coupler ensures the compressor drivetrain operates exactly as designed. Non-OEM substitutes may vary in elastomer stiffness, dimensional tolerances, or bonding quality, which can introduce vibration and reduce system reliability.

This OEM coupler provides dependable torque transmission, protects shafts and bearings from excessive stress, and supports long service life for both engine and air-end assemblies. For portable compressor equipment operating in construction and industrial environments, OEM components are critical for maintaining reliability and minimizing downtime.
