The Ruland Bellows Coupling designed to deliver exceptional torsional stiffness, making it ideal for precision applications. Built with two anodised aluminium hubs and a stainless steel bellows, it combines lightweight construction with the capability to accommodate various misalignments. Its unique design features fewer convolutions compared to typical couplings, allowing it to excel in high speed environments, reaching up to 10,000 RPM. The manufacturing process adheres to stringent ISO 9001:2015 standards, ensuring reliability and quality. With RoHS3, REACH, and Conflict Minerals compliance, this coupling not only meets but exceeds industry standards.
Engineered for high stiffness accommodating significant torsional loads
Constructed from materials sourced exclusively from North American mills
Features a balanced design to minimise vibrations at elevated speeds
Machined from high grade aluminium for reduced weight and low inertia
Meets and exceeds DIN 912 12.9 standards for maximum torque capabilities
Designed for easy installation with metric hardware included
Offers zero backlash performance for enhanced precision in motion control
