Compressor Couplings – OEM Solutions for Stationary and Mobile Compressors

Compressor couplings play a critical role in ensuring reliable power transmission, vibration damping, and long service life. Depending on the compressor type — stationary or mobile — different coupling designs are required to handle alignment, torque transfer, and torsional vibrations.

Stationary Compressors – Electric Motor Drives

In stationary compressors, typically powered by electric motors, the most common solution is the ROTEX® type coupling. These use two metallic hubs and a central elastomer spider to provide:

• Compact design with easy installation
• Reliable torque transfer for continuous duty
• Good misalignment compensation
• Minimal maintenance requirements

ROTEX couplings are a trusted standard in industrial compressors where stable and efficient performance is required.

Mobile Compressors – Diesel Engine Drives

Mobile compressors are driven by diesel engines, which produce significant torsional vibrations. To protect the drivetrain, torsionally flexible couplings are essential.

In this case, solutions like:

• BoWex® Elastic couplings
• CENTAFLEX® rubber elements

…are used to compensate for misalignment, vibrations, and shock loads. These flexible elements ensure smooth operation and help extend the lifespan of the entire compressor system.

Leading OEM Manufacturers

Trusted producers such as CENTA, KTR, Rexnord and Stromag offer dedicated compressor coupling solutions. Each coupling is preselected and carefully calculated for the specific engine or motor setup, ensuring:

• Optimal damping performance
• Maximum longevity under heavy load conditions
• Safe and reliable operation in both stationary and mobile environments

Why Choose Original OEM Compressor Couplings?

If your compressor was originally equipped with a coupling from KTR, CENTA, Rexnord or Stromag, it is always best to use the same OEM element for replacement. Original couplings guarantee:

• Stable, predictable performance
• Correct Shore hardness and torsional stiffness
• Compatibility with existing hubs and bolts
• Proven reliability in demanding compressor applications
