Bellows couplings for printing
Bellows couplings with high torsional stiffness that can accommodate all forms of misalignment are well suited for large format printers, 3-D printers, offset printers, web converting equipment, and print finishing equipment.
Bellows couplings from Ruland - and available in the UK from Techdrives - 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 10,000rpm. Balancing also helps reduce the risk of common printing errors such as banding.
