The Ruland six beam coupling designed for high precision applications, featuring bores of 21mm and 17mm to accommodate a range of shaft sizes and improve alignment capabilities.
Machined from a single piece of 7075 aluminium for low inertia and strength
Increased misalignment tolerance due to wider beam spacing compared to other series
Reference mark on the outer diameter for easy identification of bore sizes
Complies with RoHS3, REACH, and Conflict Minerals standards for environmental safety
