The Ruland High stiffness bellows coupling designed to excel in precision positioning applications. Engineered with a unique combination of anodised aluminium hubs and a stainless steel bellows, this coupling offers lightweight durability while maintaining low inertia levels. Its sophisticated design features fewer convolutions than typical misalignment styles, significantly enhancing torsional stiffness. Capable of accommodating various forms of misalignment, its 22 A ensures optimal performance even at high speeds of up to 10,000 RPM. Sourced exclusively from North American mills and crafted in an ISO 9001:2015 facility, this product exemplifies premium manufacturing standards and compliance with RoHS3 and REACH regulations, making it the perfect choice for demanding industrial applications.
