They are commonly used in industrial, medical, and autonomous robotic systems requiring high speed and accuracy.

Ruland bellows couplings are designed for high-torque and zero-backlash applications, which are essential for robots requiring precision motion control. These couplings are lightweight, have low inertia, and can accommodate all forms of misalignment, making them highly versatile for
different robotic applications.

Designers benefit from using Ruland bellows couplings because they have reduced vibrations at speeds up to 10,000rpm due to a balanced design.

They are also available in standard lengths for increased torsional stiffness and extended lengths for increased misalignment capabilities. These options allow designers to use the bellows coupling that best
fits their application.

Ruland bellows couplings are available in clamp-style designs, with bore sizes ranging from 3 mm to 45mm. Hubs are manufactured from meticulously selected 2024 T-351 aluminium bar stock for high strength and low inertia. Bellows are made from stainless steel, giving the coupling flexibility under torsional loads.

Each coupling undergoes a proprietary
assembly process to ensure it does not introduce misalignment, causing high bearing loads into the system.

Ruland carefully manufactures bellows couplings in its ISO 9001:2015 certified advanced manufacturing facility in Marlborough, Massachusetts, using strict controls and proprietary processes. They comply with RoHS3, REACH, and Conflict Minerals, ensuring they meet global environmental sustainability and safety
standards.
