The Ruland High Stiffness Bellows Coupling is engineered for precision and reliability in various industrial applications. Designed with 20mm x 20mm bores, it offers exceptional torsional stiffness due to its unique construction, which features fewer convolutions than typical couplings. This design not only enhances performance in precision positioning tasks but also allows for greater misalignment accommodation. The coupling comprises anodised aluminium hubs paired with a stainless steel bellows, optimising weight and inertia for enhanced operational efficiency. Its balanced design reduces vibration, making it suitable for high speed applications of up to 10,000 RPM. Manufactured in an ISO 9001:2015 certified facility, this product adheres to the highest standards of quality and compliance, including RoHS3 and REACH certifications, ensuring it meets industrial requirements while prioritising safety and performance.
