The Ruland High Stiffness Bellows Coupling has fewer convolutions than comparably sized increased misalignment styles, providing increased torsional stiffness, making it ideal for precision positioning applications. It is comprised of two anodized aluminum hubs and a stainless steel bellows for a lightweight and low inertia design. Engineered with a balanced design, it reduces vibration at high speeds up to 10,000 RPM. The thin walls of the bellows flex while remaining rigid under torsional loads, accommodating all forms of misalignment.
