Ruland MBS15-4-4-A is a bellows coupling with 4mm x 4mm bores, 15.0mm OD, and 27.2mm length. It is zero-backlash and has a balanced design for reduced vibration at high speeds. MBS15-4-4-A is comprised of two anodized aluminum hubs and a stainless steel bellows. The bellows are able to flex while remaining rigid under torsional loads allowing for all types of misalignment to be accommodated. This bellows coupling is lightweight and has low inertia making it suitable for applications with speeds up to 10,000 RPM. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. Ruland manufactures MBS15-4-4-A to be torsionally rigid and an excellent fit for precise positioning stepper servo applications as well as encoders. It is machined from solid bar stock that is sourced exclusively from North American mills. MBS15-4-4-A is carefully manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
