BELLOWS COUPLINGS FOR ROBOTICS
Suitable for
high-torque and zero-backlash
applications, Ruland’s bellows couplings are ideal for
precision motion in robotic applications
WHY CHOOSE RULAND BELLOWS COUPLINGS?
• Ideal for precise motion in robotic systems, offering high torque and torsional stiffness • Reduced vibration at speeds up to 10,000 rpm due to a balanced design • Long lengths for increased misalignment and standard lengths for maximum torsional stiffness
Ruland bellows couplings have varied designs, speed capabilities up to 10,000 rpm, and a wide size range, making them an ideal choice for new robot designs
R
uland bellows 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. The company’s 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.
BENEFITS TO DESIGNERS For designers, there are many benefits to using Ruland bellows couplings. For a start, 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 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 introduce misalignment, causing high bearing loads into the system.
MEETING SUSTAINABILITY AND SAFETY STANDARDS Ruland carefully manufactures its bellows couplings in its ISO 9001:2015 certified advanced manufacturing facility in Marlborough, Massachusetts, using strict controls and proprietary processes. These comply with RoHS3, REACH, and Conflict Minerals, ensuring they meet global environmental sustainability and safety standards.
• Carefully made in Ruland’s Marlborough, Massachusetts advanced manufacturing facility
• Available for immediate delivery • RoHS3, REACH, and Conflict Minerals compliant.
