Ruland’s bellows couplings are comprised of two anodized aluminum hubs and a stainless steel bellows, for a lightweight, low inertia design 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. They 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 to 1 in. (3 to 25 mm). 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.
