Bellows couplings are available in clamp and set screw styles with or without keyways in bore sizes from 1/8” (3mm) to 1” (25mm).

Marlborough, MA - Ruland manufactures bellows couplings with high torsional stiffness that can accommodate all forms of misalignment and are well suited for large format printers, 3-D printers, offset printers, web converting equipment, and print finishing equipment.

Bellows couplings from Ruland are comprised of two anodized aluminum 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.

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" (3mm to 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.

Established in 1937, Ruland focuses on the design and manufacture of high performing shaft collars and couplings. All products are carefully manufactured in Marlborough, Massachusetts under strict controls using proprietary processes. 3D CAD files, full product specifications, and additional technical information, are available at
