The Ruland High Stiffness Bellows Coupling is engineered for precision applications, excelling in the most demanding environments. With its unique combination of lightweight anodised aluminium hubs and a stainless steel bellows, it offers exceptional performance while minimising inertia. The design features fewer convolutions compared to similar products, thereby enhancing torsional stiffness and making it an ideal choice for applications requiring enhanced precision and reliability. Its balanced construction effectively reduces vibration, allowing it to operate reliably at speeds of up to 10,000 RPM.
