Ruland jaw couplings are a three-piece assembly comprised of two hubs press fit onto a spider. They are zero-backlash and have a balanced design for smooth operation at higher speeds. The spider comes in three different materials allowing the user to customize dampening, misalignment, and torque. All jaw coupling hardware is metric and tests beyond industry standards for maximum performance capabilities. Jaw couplings are machined from solid bar stock that is sourced exclusively from North American mills.
