438 224-2 Stromag Periflex Drive Coupler | OEM Elastomeric Industrial Coupling

The 438 224-2 Stromag Periflex Drive Coupler is a heavy-duty flexible coupling designed for industrial and power-transmission applications where reliable torque transfer, vibration damping, and drivetrain protection are essential. As part of the Stromag Periflex series, this coupler utilizes a highly resilient elastomer element to isolate torsional vibration while maintaining smooth, consistent power transmission between rotating shafts.

Stromag Periflex couplings are commonly specified in rotary screw air compressors, generator sets, pumps, conveyors, and processing equipment due to their rugged construction and proven performance in harsh operating environments. The 438 224-2 coupler functions as a mechanical buffer between the prime mover and driven equipment, absorbing shock loads and compensating for shaft misalignment that naturally occurs during operation.

This coupling is engineered for continuous-duty service in applications subject to fluctuating loads, vibration, and thermal expansion.

Functional Design and Performance

The 438 224-2 Stromag Periflex coupler uses a high-strength elastomer ring mounted between rigid metallic flanges to create a torsionally flexible shaft connection. This design allows the coupling to absorb vibration and transient torque spikes before they are transmitted into the drive system.

In applications such as compressors and generator sets, torsional oscillations can accelerate wear on shafts, bearings, gearboxes, and driven components. The elastomer ring within the Periflex coupling reduces these forces, improving drivetrain stability and extending the service life of connected equipment.

The flexible construction also compensates for installation tolerances and thermal expansion, helping maintain alignment during operation without introducing excessive mechanical stress.

Performance Advantages

The 438 224-2 Stromag Periflex Coupler delivers stable, vibration-controlled torque transfer that enhances reliability across the entire drive system. By isolating torsional vibration, it reduces mechanical noise, limits wear on bearings and shafts, and helps prevent costly downtime caused by premature component failure.

Compared to rigid couplings or generic flexible couplers, Stromag Periflex couplings are engineered with elastomer materials optimized for industrial drive requirements. This ensures predictable damping performance, consistent torque transmission, and long-term durability under fluctuating loads.

Using the correct Periflex coupling helps preserve original equipment performance, alignment accuracy, and operational efficiency.
