    Rigid Couplings for Robotic Systems

    Rigid couplings are often the optimal choice in precision servo-driven systems in which no misalignment is present. Ruland rigid couplings are manufactured with precision honed bores to ensure collinearity for a precise fit and greater torque transmission. Non-collinear bores introduce small amounts of misalignment that reduce the otherwise substantial benefits of using a rigid coupling. Rigid couplings have the highest torque rating and torsional stiffness of any coupling offered by Ruland. Torque is a very common challenge in robotic systems design, especially for robots that are required to lift or manipulate heavy loads.
    Ruland rigid couplings are shipped with screws treated with proprietary Nypatch anti-vibration coating, allowing for even seating of the screw, repeated screw installations, and reduced galling. Bore sizes are available from 1/8” to 2” and 3mm to 50mm. Rigid couplings are available in set screw and one- and two-piece clamping styles and manufactured in a variety of materials: 1215 lead-free steel with a black oxide finish for the highest holding power, lightweight 2024 aluminum for low inertia, and 303 stainless steel for corrosion resistance.
