Reich Drive Coupler Guide
Reich is one of the most recognized names in torsional coupling technology, known globally for designing high-performance power transmission components for compressors, pumps, diesel-driven machinery, hydraulic systems, and industrial equipment operating under heavy load conditions. Their couplers are engineered for precision torque transfer, vibration control, and durability in demanding environments where reliability is essential. At Stark Industrial Products, we supply Reich couplers built to maintain the performance and mechanical integrity that operators expect from this respected manufacturer.
Reich’s engineering philosophy revolves around high torsional flexibility, exceptional misalignment capability, and long service life under continuous stress. Many Reich designs, such as the ARCUSAFLEX, MULTI MONT SELLA, and REIBO families, are used in industrial compressors, generator sets, processing equipment, and pump systems worldwide. These applications place immense stress on the connection between the prime mover and the driven component. A correctly matched Reich coupler ensures that vibration is absorbed, torque is transmitted smoothly, and both connected shafts remain protected from shock loads and structural stress. Stark Industrial Products helps facilities across the country secure the right Reich coupling for their system quickly and accurately.
Why Reich Machinery Relies on Properly Matched Drive Couplers
Reich couplers are found in machinery where vibration, torque spikes, thermal expansion, and continuous run cycles are normal operating conditions. Plants in manufacturing, chemical processing, natural gas compression, wastewater management, mining, and material handling rely on Reich couplers to maintain the stability of their rotating equipment. Using the correct model is crucial because each Reich design is tuned for specific torsional stiffness, alignment tolerances, and dynamic characteristics. A mismatched coupler can introduce excessive vibration, overload bearings, disrupt timing relationships, or cause catastrophic shaft failure.
To maintain optimal operation, the coupler must match the machine’s torque requirements, rotational speed, flywheel interface (if applicable), bore dimensions, keyway specifications, and axial movement allowance. Stark Industrial Products supplies the proper Reich configurations and supports operators in selecting the exact match for their machinery, ensuring long-term reliability and smooth operation.
How to Identify the Correct Reich Coupler
Identifying the correct Reich coupling begins with locating the part number, typically printed or stamped on the hub, element, or nameplate. If the marking has worn off, measurements are essential. This includes outer diameter, hub length, bolt-hole pattern, flywheel interface dimensions for ARCUSAFLEX units, bore sizes, and the type of rubber or elastomer element used. Reich’s product families include many variations, and even slight dimensional differences matter when aligning heavy-duty rotating equipment.
If you are unsure which coupler your equipment requires, we strongly encourage sending photos of the existing component, the equipment nameplate, or the shaft/hub measurements. Stark Industrial Products identifies Reich couplers for customers every day and ensures that the correct version is selected the first time, reducing downtime and preventing rework or installation issues.

Common Causes of Coupler Issues in Reich-Equipped Machinery
Although Reich couplers are built to withstand extreme mechanical stress, several conditions can reduce service life. Common factors include shaft misalignment, excessive torsional vibration, aging elastomer elements, thermal deformation from high-duty cycles, improper installation, and environmental contamination. In diesel- or engine-driven applications, couplers may also experience variable load patterns that accelerate fatigue if not properly matched. Early signs of trouble include cracking or splitting of the element, metallic dust around the hubs, unusual vibration, and increased noise. Replacing the coupling promptly with the correct Reich model restores vibration damping, protects critical components, and maintains efficient power transmission.
