Boss 310027 OEM Drive Coupler | Compressor Motor-to-Air-End Coupling

The Boss 310027 OEM Drive Coupler is an original equipment flexible coupling engineered specifically for use in Boss compressor drive assemblies. This component connects the prime mover—typically an electric motor or engine—to the compressor air-end, allowing rotational power to be transmitted efficiently while absorbing torsional vibration and compensating for minor shaft misalignment.

In industrial compressor systems, the drive coupler is one of the most critical mechanical interfaces in the machine. Incorrect elastomer properties, insufficient vibration damping, or dimensional inaccuracies can lead to excessive noise, accelerated bearing wear, shaft damage, and premature air-end failure. The Boss 310027 coupler is manufactured to Boss OEM engineering standards to ensure correct fitment, balance, and long-term operational reliability.

This coupler is designed for continuous-duty compressor environments where equipment operates under fluctuating loads, temperature changes, and extended run cycles.

Functional Design and Performance

The Boss 310027 OEM drive coupler utilizes a resilient elastomer element bonded to precision-machined metal hubs. This construction allows the coupler to function as a torsional buffer, isolating vibration and transient torque spikes before they are transmitted into the compressor drive train.

During startup, shutdown, and load changes, compressors generate torsional shock that can place significant stress on shafts, bearings, and seals. The elastomer element within the 310027 absorbs these forces, helping maintain alignment, reduce mechanical noise, and protect adjacent components from damage.

Because this is a genuine OEM Boss component, the elastomer hardness, bonding process, and hub geometry are matched exactly to compressor operating characteristics. This ensures predictable damping behavior, consistent torque transfer, and reliable performance throughout the service life of the coupler.

Advantages of Using a Genuine Boss OEM Coupler

Using the Boss 310027 genuine OEM drive coupler ensures your compressor drive system operates exactly as designed. Non-OEM or incorrect couplers may differ in elastomer stiffness, balance, or dimensional tolerances, which can introduce excessive vibration, reduce efficiency, and shorten air-end life.

This OEM coupler delivers consistent torque transmission, minimizes mechanical stress on connected components, and helps extend the service life of bearings, shafts, and compressor air-ends. For mission-critical compressed air systems, genuine OEM components are essential for maintaining uptime and reliability.
