Ruland Bellows Coupler 25.4 mm Outer Diameter, 10 mm and 8 mm Bore Sizes, 33.3 mm Length, Clamp Style MBC25-10-8-A

Ruland MBC25-10-8-A is a precision bellows coupler designed for mechanical power transmission applications requiring zero backlash and vibration reduction at high speeds. It features a 25.4 mm outer diameter and a length of 33.3 mm, with bore sizes of 10 mm and 8 mm on the respective sides. The clamp-style coupler incorporates anodized aluminum hubs and a stainless steel bellows that offers flexibility while maintaining torsional rigidity.

The coupler accommodates all types of misalignment including axial (0.3 mm), parallel (0.1 mm), and angular (1.5°) misalignments, making it suitable for demanding industrial and laboratory environments.

Its lightweight and low moment of inertia (2.725 x 10^-6 kg/m²) enable operation up to a maximum speed of 10,000 RPM, ensuring smooth torque transmission with a rated torque capacity of 6.8 Nm. The coupler uses M3 screws and complies with REACH, RoHS3, and DIN 912 12.9 standards for mechanical strength and environmental safety.

Operating temperature ranges from -40°C to 93°C allow this coupling to perform reliably in diverse industrial, laboratory, and manufacturing settings. Its zero-backlash and torsionally rigid design makes it an excellent fit for applications such as precise positioning stepper motors, servos, and encoders.

The coupler is clamp style with anodized aluminum hubs and stainless steel bellows for durability. It allows axial, parallel, and angular misalignment compensation within specified tolerances. Suitable for high-speed applications up to 10,000 RPM due to balanced design and low inertia.

Torque rating of 6.8 Nm with metric hardware exceeding DIN 912 12.9 standards. Operates reliably within a temperature range of -40°C to 93°C. Ideal for precise positioning in stepper servo and encoder applications. Manufactured in the United States from solid bar stock with strict quality controls.

Ruland ensures high-quality manufacturing from North American sourced solid bar stock at their Marlborough, MA facility using proprietary processes.
