Bellows Couplings for Encoders

Ruland bellows couplings are comprised of two anodized aluminum and 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. They are the most torsionally stiff flexible coupling Ruland offers making them a good fit for encoders that require the highest level of resolution. When designers select a bellows coupling for an encoder they must control for misalignment. While bellows couplings to accommodate all forms of misalignment, they are not as flexible as beam or controlflex types. Bellows couplings are manufactured in our Marlborough, Massachusetts factory with bore sizes ranging from 1/8” to 1” or 3mm to 25mm.
