46492971 Ingersoll Rand OEM Drive Coupler | Compressor Motor-to-Air-End Coupling

The 46492971 Ingersoll Rand OEM Drive Coupler is an original equipment flexible coupling designed specifically for use in Ingersoll Rand compressor drive systems. This component connects the electric motor or engine to the compressor air-end, transmitting rotational power efficiently while isolating torsional vibration and compensating for minor shaft misalignment during operation.

In rotary screw compressor applications, the drive coupler plays a vital role in maintaining drivetrain stability. Improper or worn couplers can allow excessive vibration and shock loads to transfer directly into shafts, bearings, and seals. Over time, this may result in premature wear, reduced compressor efficiency, and unexpected downtime. The 46492971 coupler is manufactured to Ingersoll Rand’s OEM dimensional and material specifications to ensure correct fitment and reliable performance under demanding industrial conditions.

This coupler is engineered for continuous-duty compressor operation where temperature fluctuations, load transitions, and extended run times are common.

Functional Design and Performance

The 46492971 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, rotary screw compressors generate significant torsional forces. The elastomer element within the 46492971 absorbs these loads, reducing mechanical stress on connected components and helping maintain proper alignment between the motor and air-end.

Because this is a genuine OEM Ingersoll Rand component, the elastomer compound and geometry are engineered specifically for the operating characteristics of Ingersoll Rand compressor systems. This ensures consistent torque delivery, predictable damping behavior, and long service life in industrial environments.
