Product Description
Ruland MBC25-6-6-A is a flexible bellows coupler designed for precise power transmission in demanding industrial applications. Featuring a 25.4 mm outer diameter, 6 mm bore sizes on both ends, and a length of 33.3 mm, this coupler achieves zero backlash and excellent torsional rigidity courtesy of two anodized aluminum hubs and stainless steel bellows.
The balanced design reduces vibration at high speeds up to 10,000 RPM, while the bellows flex to accommodate angular, parallel, and axial misalignments without compromising torque transmission. Its lightweight and low inertia characteristics make it suitable for positioning stepper motors, servo applications, and encoding devices where precision is paramount.
Operating effectively in environments from -40°C to 93°C, the MBC25-6-6-A includes metric M3 hardware tested beyond DIN 912 12.9 standards for maximum torque. Manufactured exclusively from solid bar stock sourced in North America and built with advanced proprietary processes in Ruland's Marlborough, MA facility, this coupler ensures quality and reliability for mechanical power transmission needs.
