Product Description

Ruland MBC33-12-12-A mechanical power transmission coupling is a high-precision bellows type designed to provide zero backlash and reduced vibration in demanding industrial applications. The clamp style hubs are machined from anodized aluminum bar stock, and the bellows are crafted from stainless steel, allowing flexibility to handle angular, parallel, and axial misalignment while maintaining torsional rigidity.

With an outer diameter of 33.3 mm, bore sizes of 12 mm each, and a length of 42.9 mm, this coupling is suitable for high-speed applications up to 10,000 rpm and torque ratings up to 13.6 Nm. Its low moment of inertia enhances dynamic response making it an excellent choice for stepper motor, servo motor, and encoder installations requiring precise positioning.

The coupling operates efficiently within a temperature range from -40°C to 93°C and is compliant with REACH, DIN 912 12.9, and RoHS3 standards, ensuring compatibility in various industrial, laboratory, and manufacturing settings. Metric hardware further supports ease of assembly and reliable torque transmission.

Its balanced design reduces vibration and noise, enhancing longevity and performance under rigorous operating conditions. Manufactured in the United States under strict quality control, this coupling represents a reliable solution for applications in automation, robotics, and mechanical drives.

The coupling features a clamp style for secure hub attachment. It accommodates angular misalignment up to 1.5 degrees, parallel up to 0.15 mm, and axial up to 0.4 mm. Rated torque capacity is 13.6 Nm with a maximum speed of 10,000 rpm.

Constructed with anodized aluminum hubs and stainless steel bellows for durability. Lightweight and torsionally rigid design minimizes vibration at high speeds. Manufactured to REACH, DIN 912 12.9, and RoHS3 standards. Ideal for precise positioning stepper servo and encoder applications.
