Bellows couplings for printing applications

Ruland’s bellows couplings are comprised of two anodised aluminium hubs and a stainless steel bellows creating a lightweight, low inertia coupling that can accommodate all types of misalignment – parallel, angular, axial motion, and complex.

The thin walls of the hydro-formed bellows maintain low bearing loads and flexibility while remaining rigid under torsional loads. Ruland bellows coupling have a balanced design for reduced vibration in applications up to 10,000 RPM. Balancing also helps reduce the risk of common printing errors such as banding.
