Bellows Couplings

Ruland bellows couplings, available thru Pacific International Bearing Sales, are ideal for high-performance servo and stepper motor applications requiring precise motion control. These zero-backlash couplings feature a balanced design and combine high torque capacity with excellent torsional stiffness, while accommodating angular, axial, and parallel misalignment. Constructed with lightweight anodized aluminum hubs and a flexible stainless steel bellows, they support speeds up to 10,000 RPM with minimal inertia. Available in clamp-style with or without keyways, in inch, metric, and mixed bore sizes from 1/8" to 1 3/4" and 3mm to 45mm.
