The Ruland Bellows Coupling is engineered for precision positioning applications, providing exceptional torsional stiffness and accommodating various forms of misalignment. Crafted from lightweight, anodised aluminium hubs and durable stainless steel bellows, this coupling ensures low inertia and enhanced operational efficiency at speeds up to 10,000 RPM. Designed with fewer convolutions than comparable models, it optimises stiffness, thereby effectively reducing vibration during high speed operations. Manufactured under stringent quality controls in an ISO 9001:2015 certified facility, this coupling exemplifies excellence in design and production.
