Rigid Couplings for Automation & Linear Motion
Rigid couplings are manufactured from a single piece of material with no flexing elements giving them the greatest torque and torsional stiffness capabilities of any coupling Ruland offers. They are ideal for applications that require the highest degree of accuracy and repeatability. Automation and linear system designers prefer to use clamp as opposed to set screw type rigid couplings because they have increased holding power, will not mar the shaft, and have standard aluminum options for lightweight and low inertia.
Ruland manufactures rigid couplings with precision honed bores on straight bore couplings to ensure collinearity for a precise fit and greater torque transmission capability. Collinear bores prevent the coupling from introducing misalignment into systems where it would not otherwise be present allowing for reduced wear on joined components and increased system efficiency. Ruland manufactures rigid couplings in set screw and one- and two-piece clamp styles in 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. Bores are available in sizes from 1/8” to 2” and 3mm to 50mm.
