Bellows Couplings for Conveyors
Bellows couplings are comprised of two anodized aluminum hubs mounted to a stainless steel bellows creating a low inertia zero-backlash coupling that is well suited for speeds up to 10,000 RPM. The thin wall of the bellows allows the coupling to remain flexible under misalignment conditions while maintaining rigidity under torsional loads. Precision conveyors for semiconductor such pallet conveyors often require high speed and torque, which are two of the primary benefits of using a bellows coupling. These conveyors may be positioning sensitive items worth tens of thousands of dollars or more. Size for size, bellows are the stiffest flexible coupling Ruland offers reducing the likelihood of vibration or windup adversely impacting the system. Bellows couplings are manufactured in our Marlborough, Massachusetts factory in bore sizes ranging from 1/8” to 1” or 3mm to 25mm.
