Backlash-Free Couplings for High-Tech Applications

For high technology applications such as test and measurement, inspection, liquid handling, semi-conductor, solar panel production equipment, print, and packaging automation, as well as medical devices, Ruland manufactures a variety of components including oldham couplings and beam couplings.
are comprised of two with drive tenons that mate with a . This design results in a highly customizable shaft coupling giving users over 25,000 standard combinations to choose from. Oldham couplings from Ruland are specified as an assembly, making it easy to combine clamp or set screw hubs in stainless steel or aluminum with inch or metric and keyed or unkeyed bores. Oldham couplings are especially useful in applications where parallel misalignment is present. However, they are used in many non-misalignment applications as well due to their light bearing loads, low inertia, electrical isolation, and cost-effectiveness.
Commonly used in
, the has multiple spiral cuts machined into a single piece of aluminum. Ruland couplings have the industry's highest torque and torsional stiffness due to the proprietary beam design. Beam couplings offer low inertia and accommodation of all forms of misalignment. The cut pattern ensures backlash-free operation and allows for minor shock absorption. Stainless steel versions are also available for applications requiring higher torque transmission capabilities and corrosion resistance.All Ruland beam and oldham couplings are compliant with RoHS, REACH, and Conflict Minerals. Ruland carefully manufactures them from meticulously selected bar stock in our advanced manufacturing facility in Marlborough, Massachusetts. Special solutions such as, custom bore tolerances, geometries, sizes, and other alterations can be designed by our experienced in-house engineers.
