Ruland Bellows Coupling, 69.9mm Outside Diameter, 24 mm, 32 mm Bore, 87.1mm Length Flexible Coupling

The Ruland High Stiffness Bellows Coupling is engineered to meet the demanding needs of precision positioning applications. Crafted with two anodised aluminium hubs and a robust stainless steel bellows, the design prioritises lightweight durability and low inertia, allowing it to excel in high speed operations of up to 10,000 RPM. The thoughtful design incorporates fewer convolutions when compared to increased misalignment styles, enabling enhanced torsional stiffness. Ideal for accommodating various forms of misalignment, this coupling ensures seamless performance. Manufactured in an ISO 9001:2015 certified facility in Marlborough, MA, it adheres to stringent quality controls and complies with RoHS3, REACH, and Conflict Minerals standards, ensuring it meets both safety and environmental regulations.
