Bellows Couplings for Robotic Systems
Ruland zero-backlash bellows couplings are comprised of two anodized aluminum hubs and a flexible stainless steel bellows allowing for a lightweight, high torque solution that is required for many robot designs. The stainless steel bellows remain rigid under torsional loads while accommodating all forms of misalignment. Ruland manufactures bellows couplings with a balanced design for reduced vibration at speeds up to 10,000 RPM.
Bellows coupling have the greatest size-for-size torque and torsional stiffness of any Ruland flexible coupling making them a common choice for surgical robots where high torsional stiffness is preferred to ensure accurate positioning. They are available in clamp and set screw hubs with or without keyways in bore sizes from 1/8” to 1” and 3mm to 25mm.
