BELLOWS COUPLINGS FOR PRECISION MOTION IN ROBOTIC APPLICATIONS
Available in various styles and offering such benefits as zero-backlash, high torque and torsional stiffness, bellows couplings can be used in a wide range of robotic applications in a variety of industries. Ruland explains

ellows couplings are ideal for precision motion in robotic applications due to their zero-backlash design, high torque
and torsional stiffness, and various styles that ensure accurate movement and smooth operation. 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.
HOW CAN DESIGNERS BENEFIT FROM BELLOWS COUPLINGS? Designers benefit from using Ruland bellows couplings because they have reduced vibrations at speeds up to 10,000 rpm 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 3mm 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
