Reich Kupplungen - Arcusaflex rubber disc couplings

In the world of industrial power transmission, torsional flexibility and reliability are paramount—especially in gas engine applications. One standout solution is the Reich Arcusaflex® rubber coupling, a highly flexible flange coupling designed to meet the demanding requirements of internal combustion engines. With over 70 years of engineering excellence, Reich Kupplungen has earned its reputation for delivering smooth and efficient performance across industries.

What Is the Arcusaflex® Coupling?

The Arcusaflex® is a highly torsionally flexible rubber disc coupling with an axial plug-in design, making it ideal for internal combustion engine drives. Its rubber elements absorb torsional vibrations and shocks, protecting connected machinery and enhancing operational longevity.

Key Features:

• High torsional flexibility for vibration damping
• Axial plug-in capability for easy installation
• Rubber disc design for smooth torque transmission
• Customizable configurations for specific engine setups

Application in Gas Engines

Gas engines—especially those used in power generation, marine propulsion, and industrial machinery—demand couplings that can handle fluctuating loads and high torque. Arcusaflex® couplings are particularly well-suited for:

• Guascor gas engines, known for their robust performance in energy and industrial sectors
• Cogeneration systems, where vibration damping improves efficiency
• Pump and compressor drives, where smooth torque transmission is critical

The coupling’s ability to absorb torsional vibrations ensures quiet operation, reduced wear, and extended equipment life—all vital for gas engine applications.

Replace Existing Couplings in Guascor Generating Sets with Reich Couplings

Upgrade Your Powertrain with Precision-Engineered Reich Couplings

Guascor generating sets are widely used in power generation applications for their durability and performance. However, over time, the original couplings installed between the engine and alternator may wear out, become obsolete, or fail to meet evolving operational demands. That’s where Reich Kupplungen steps in—with a proven solution to replace existing couplings with high-performance Reich couplings, including the renowned Arcusaflex® series.

Seamless Replacement—Tailored to Your Setup

Whether your Guascor genset was originally fitted with couplings from other manufacturers or you're facing compatibility issues, Reich offers custom-engineered replacements that match your system’s mechanical and performance requirements.

What We Need to Deliver a Perfect Fit:

To design and supply a compatible Reich coupling, customers simply need to provide:

• Engine shaft connection details (e.g., shaft diameter, keyway dimensions, bolt pattern)
• Alternator flange or shaft technical specifications (e.g., flange type, bolt circle, pilot diameter, shaft length)

With this information, Reich engineers can precisely configure a coupling that ensures optimal alignment, torque transmission, and vibration damping.

Why Replace with Reich?

Reich couplings are engineered for longevity, flexibility, and reliability—making them ideal for demanding generator applications.

Benefits of Switching to Reich:

• 🛠️ Custom-fit design for any engine/alternator combination
