Bellows couplings for printing applications
Ruland is promoting its range of bellows couplings that are characterised by high torsional stiffness. This type of coupling can accommodate all forms of misalignment, with typical applications being found in large-format printers, 3D printers, offset printers, web converting equipment, and print finishing equipment.
The thin walls of the hydro-formed bellows maintain low bearing loads and flexibility while remaining rigid under torsional loads. The bellows couplings 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.
Ruland bellows couplings are zero-backlash and have no moving parts, ensuring a long maintenance-free life. They are available in inch, metric, and inch to metric bore combinations ranging from 1/8" (3mm) to 1" (25mm). Hubs are offered in clamp and set screw styles with or without keyways. Couplings are supplied with metric hardware, DIN12.9 cap screws on clamp couplings for maximum torque capabilities. Stainless steel hubs, inch hardware, and custom designs are available by special request.
Bellows couplings are part of Ruland's complete coupling line, which includes beam, disc, zero-backlash jaw, oldham, and rigid. All Ruland couplings are manufactured in its Marlborough, Massachusetts factory and are RoHS2 and REACH compliant.
