The Ruland aluminium double disc coupling is designed to provide a highly efficient and reliable connection between shafts while compensating for various misalignments. With its robust construction, it ensures zero backlash during operation, enhancing the precision of positioning in critical applications. The uniquely engineered design facilitates exceptional performance at high speeds, making it ideal for industries such as semiconductor and machine tool manufacturing. The coupling's lightweight nature and low inertia allow it to operate smoothly at speeds up to 10,000 RPM. Furthermore, the combination of anodised aluminium hubs and stainless steel disc springs guarantees durability and longevity under demanding conditions. This coupling does not merely connect shafts

it elevates system performance by isolating electrical currents, ensuring safe and efficient operation.
