This ACH6.5WN Reich Arcusaflex Drive Coupler is a highly flexible rubber disc flange coupling. It is expertly manufactured by REICH-Kupplungen. The designation ACH6.5WN indicates a specific coupling size (Size 6.5) and the particular rubber element stiffness. The WN version signifies a very soft rubber element, typically around 55° Shore A. This soft composition is specifically engineered to provide maximum vibration isolation in internal combustion engine drives. It provides the most torsionally soft connection available in the standard range.
Product Quality and Function
- Stark Industrial Products guarantees all of our drive couplers are Original Equipment Manufacturers’ (OEM) equipment. Thus, we only offer OEM unless we are matching a discontinued item.
- This Arcusaflex coupling features a disc-shaped rubber element. Therefore, it provides superior torsional elasticity. This effectively isolates and dampens engine-generated vibration.
- In addition, the highly flexible nature of the element absorbs high shock loads. This is essential for protecting the engine and driven machine components.
- Moreover, the design features an axial plug-in facility. This ensures both simple, fast installation and ease of element replacement.
- The coupling accommodates significant positioning inaccuracies. This includes compensation for radial, angular, and axial shaft misalignments.
- Since it is constructed with quality elastomeric materials, the coupling transmits torque with virtually no backlash. This guarantees smooth and reliable power flow.
- The coupling is completely maintenance-free. This means no periodic checks or lubrication are required for its service life.
Industry Applications and Brands
- Our couplings see wide use in drives for equipment across various demanding sectors.
- Specifically, the ACH6.5WN coupler is a crucial component in drivelines requiring the highest level of torsional damping. This is critical for mobile compressors, sensitive pump drives, and power generation units.
- This part is often used to connect the engine flywheel to hydraulic pumps or gearboxes. Its soft characteristics provide maximum flexibility and vibration attenuation.
- Furthermore, the coupling’s specifications often meet the requirements for heavy-duty applications. This includes marine propulsion and construction machinery using brands like Caterpillar and Cummins.
- Therefore, the Reich Arcusaflex line ensures smooth running and extended equipment life. It is compatible as a replacement for many original equipment couplings.
