The Ruland six beam coupling is designed to efficiently handle misalignment while providing robust torque capabilities. Crafted from high-grade aluminium, it serves as a reliable solution for connecting shafts in various mechanical systems.
Machined from 7075 aluminium for reduced weight and low inertia
Increased misalignment capacity due to the design of three spiral cuts on each beam
Meets DIN 912 12.9 standards, ensuring maximum torque performance
Features a reference mark on the outer diameter for easy identification
Manufactured in the USA under stringent quality controls
