Ruland 33 mm OD 10 mm Bore Stainless Steel Bellows Clamp Coupler 42.9 mm Length MBC33-10-10-A

Ruland MBC33-10-10-A is a high-performance flexible bellows clamp coupler engineered for reliable mechanical power transmission. Featuring a 33 mm outer diameter, dual 10 mm bores, and an overall length of 42.9 mm, this coupling combines robust construction with precision engineering.

The coupler consists of two anodized aluminium hubs and a stainless steel bellows element. This bellows flexes to accommodate axial, angular, and parallel misalignments while maintaining torsional rigidity, thus ensuring reliable torque transmission without backlash. Its clamp style fastening simplifies installation and ensures a secure grip.

Designed for demanding operational conditions, the coupling supports speeds up to 10,000 rpm and delivers rated torque of 13.6 Nm. It operates effectively within a temperature range of -40°C to 93°C, making it suitable for various industrial environments.

Its balanced design minimizes vibrations, making it ideal for use in precision motion control applications such as stepper and servo drives, and encoder connections. The product complies with key standards including REACH, RoHS3, and DIN 912 12.9, underlining its quality and reliability. Hardware is black-oiled alloy steel metric fasteners for corrosion resistance and strength.

Ruland's MBC33-10-10-A coupling is lightweight with low moment of inertia (10.911 x 10^-6 kg/m²), enhancing dynamic response and reducing load on connected equipment. Constructed with anodized aluminium hubs and stainless steel bellows for durability and torsional rigidity.

Clamp style fastening ensuring secure fitment and ease of assembly. Handles misalignment with angular tolerance of 1.5°, parallel tolerance of 0.15 mm, and axial tolerance of 0.4 mm. Rated maximum speed of 10,000 rpm and torque capacity of 13.6 Nm.

Service temperature range from -40°C to 93°C for versatile industrial applications. Zero backlash design reduces vibration and improves precision at high speeds. Compatible with stepper and servo drives, encoders, and light-duty power transmission.

Meets REACH, RoHS3, and DIN 912 12.9 standards with metric M3 hardware. Lightweight and low inertia for efficient dynamic performance.

This coupler is commonly used in industrial, laboratory, HVAC, manufacturing, and automation sectors where precision torque transmission and accommodation of shaft misalignment are critical.
