Product Description
Ruland MBC19-8-8-A mechanical power transmission bellows coupling clamp style is designed for precise torque transmission with minimal backlash in industrial and mechanical systems. Featuring a 19.1 mm outer diameter and 8 mm bore sizes on both ends, this coupling is 30.2 mm in length and engineered to accommodate various types of misalignment including angular (1.5°), parallel (0.1 mm), and axial (0.25 mm) without compromising performance.
The coupling consists of two anodized aluminium hubs paired with a stainless steel bellows which provides flexibility while maintaining torsional rigidity. This design reduces vibration and dynamic stress when running at speeds up to 10000 RPM, making it ideal for servo motors, encoders, and other precision drive systems.
Torque rating of 4.5 Nm and a low moment of inertia of 0.883 x 10-6 kg/m² ensure efficient power transmission with responsiveness. Operating temperatures range from -40°C to 93°C, allowing usage in varied environmental conditions.
Manufactured under strict quality controls using solid bar stock sourced exclusively from North American mills and produced in Ruland’s Marlborough, MA facility, this coupling meets REACH, RoHS3, and DIN 912 12.9 standards, guaranteeing compliance and reliability.
This clamp-style bellows coupling features metric hardware with M2.5 screws, facilitating secure assembly and maintenance. This model is suitable for industrial, manufacturing, automation, robotics, and laboratory applications requiring precise rotary position control and vibration damping.
Its lightweight aluminum construction makes it suitable for applications needing low inertia components. The stainless steel bellows ensure durability and fatigue resistance under cyclic torsional loads. Careful balancing and zero backlash design contribute to the high-performance and longevity of machinery.
Perfect for use in water treatment, HVAC, and mechanical power transmission systems. Explore more high precision mechanical couplings and power transmission solutions at EnvMart.
