PS42 Stromag OEM Drive Coupler | Heavy-Duty Flexible Industrial Coupling

The PS42 Stromag OEM Drive Coupler is a precision-engineered flexible coupling designed for industrial drive systems where high torque capacity, vibration control, and mechanical reliability are essential. Stromag couplers are widely used across compressor systems, generators, pumps, and heavy industrial equipment due to their robust construction and proven torsional damping characteristics.

This coupler connects rotating shafts between the prime mover and driven equipment, allowing torque to be transmitted efficiently while absorbing mechanical shock and compensating for minor shaft misalignment. By isolating torsional vibration, the PS42 helps protect bearings, shafts, gearboxes, and other critical drive components from premature wear and fatigue.

Designed for continuous-duty operation, the PS42 supports smooth, quiet performance in harsh environments where load variation, vibration, and temperature changes are common.

Key Features and Benefits

• OEM Stromag Drive Coupler – Manufactured to Stromag engineering and quality specifications.

• High Torque Transmission Capability – Designed for demanding industrial and power transmission applications.

• Vibration Damping Design – Absorbs torsional shock and reduces mechanical noise.

• Misalignment Compensation – Accommodates angular, axial, and parallel shaft misalignment.

• Heavy-Duty Industrial Construction – Built for continuous-duty and high-load operating conditions.

• Protective Drive System Function – Helps safeguard motors, compressors, generators, and driven components from overload stress.

• Low Maintenance Operation – Lubrication-free design with extended service intervals.

Functional Design and Performance

The PS42 Stromag Coupler utilizes a resilient elastomeric element combined with precision-machined metal components to create a torsionally flexible connection between rotating shafts. This design allows the coupling to function as a mechanical buffer, absorbing vibration and load fluctuations before they can propagate through the drive system.

In compressor and generator applications, torsional oscillations are a primary cause of bearing wear, shaft fatigue, and alignment drift. The elastomer element within the PS42 reduces these forces, improving mechanical stability and extending the service life of connected equipment.

The coupling also compensates for installation tolerances and thermal expansion that occur during operation, helping maintain proper shaft alignment and consistent torque transfer over time.

Applications and Compatibility

The PS42 Stromag Drive Coupler is commonly used in a wide range of industrial and power transmission applications, including:

• Rotary screw and piston air compressors

• Engine-driven generators and alternators

• Industrial pump and motor assemblies

• Gearbox-driven power transmission systems

• Blowers, fans, and material handling equipment

This coupler is suitable for both OEM installations and replacement applications where a Stromag-style flexible coupling is specified.

Performance Advantages

The PS42 Stromag Coupler delivers stable, vibration-controlled torque transfer that improves reliability across the entire drive system. By isolating torsional vibration, it reduces mechanical noise, minimizes wear on bearings and shafts, and helps prevent costly downtime caused by premature component failure.

Compared to generic flexible couplers, OEM Stromag couplers are engineered with specific elastomer stiffness and internal geometry matched to industrial drive requirements. This ensures consistent damping characteristics and predictable performance under varying loads and operating speeds.

Using the correct OEM coupler helps preserve original equipment performance, alignment accuracy, and long-term operational efficiency in compressors, generators, and industrial machinery.
