Product Description
Ruland MBC51-25-20-A is a premium flexible clamp coupler designed for high-performance mechanical power transmission applications. It features two anodized aluminium hubs with a 50.8 mm outer diameter and bores sized 25 mm and 20 mm respectively, connected by a precision stainless steel bellows that allows flexibility under torsional load while maintaining rigidity.
This coupler supports a high maximum rotational speed of 10,000 rpm and a torque capacity of 45.2 Nm, making it suitable for dynamic industrial environments. Its design accommodates axial, angular, and parallel misalignment (0.5 mm, 2°, and 0.25 mm respectively) without compromising performance or stability.
The lightweight aluminium hubs reduce inertia, enhancing rapid response in servo and stepper motor drives. The clamp-style fastening ensures secure, backlash-free shaft connections, aided by black-oiled alloy steel fasteners for corrosion resistance.
Operating temperature ranges from -40°C to 93°C, suitable for a wide variety of industrial, laboratory, manufacturing, HVAC, and automation settings. Certified to DIN 912 12.9, RoHS3, and REACH standards, the coupler complies with international quality and safety norms.
Stainless steel bellows enables precision flexible coupling with excellent kinematic properties. Aluminium hubs provide lightweight robustness and reduce system inertia. Clamp fastening ensures zero backlash and easy installation.
High torque capability supports demanding power transmission needs. Balanced design reduces vibration, enhancing equipment longevity. Suitable for stepper and servo drives, encoders, and general-purpose applications. Meets stringent international standards including DIN 912 12.9, RoHS3, and REACH.
