2658546432 Epiroc OEM Drive Coupler | Engine-to-Compressor Coupling

The 2658546432 Epiroc OEM Drive Coupler is an original equipment flexible coupling designed for use in Epiroc engine-driven and compressor-based systems. This component connects the prime mover—typically a diesel engine or electric motor—to a driven component such as a compressor air-end or hydraulic system, ensuring efficient rotational power transmission while isolating vibration.

In drilling and heavy equipment applications, drivetrain components are exposed to high torque loads, frequent startup cycles, and demanding field environments. Without proper torsional flexibility, shock loads can accelerate wear on shafts, bearings, and connected assemblies. The 2658546432 coupler is manufactured to Epiroc’s OEM dimensional and material specifications to ensure precise fitment, balanced rotation, and long-term reliability.

Designed for continuous-duty operation in rugged environments, this coupler supports equipment performance and helps protect critical rotating components from premature failure.

Functional Design and Performance

The 2658546432 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 drivetrain.

In drilling and compressor applications, torsional pulses and fluctuating load conditions are common. The elastomer element within the 2658546432 absorbs these forces, helping maintain alignment between connected components while reducing mechanical noise and protecting drivetrain elements from stress-related fatigue.

Because this is a genuine OEM Epiroc component, the elastomer compound and hub geometry are engineered specifically for Epiroc equipment operating characteristics. This ensures predictable damping behavior, consistent torque delivery, and reliable service life in heavy-duty field conditions.
