Oldham Couplings for Motors

Ruland oldham couplings are comprised of two anodized aluminum hubs and a center disk. Oldham couplings offer the greatest parallel misalignment accommodation of all Ruland servo couplings as well as low inertia and electrical isolation, making them a fit for a variety of motor systems. They are manufactured with a proprietary machining process for smooth interaction between the hub tenons and disk allowing for the longest service life in the industry. Ruland oldham couplings have a balanced design for reduced vibration at speeds up to 4,500 RPM.

Oldham couplings are highly versatile because of the variety of hub and insert materials available. Acetal, Nylon, and PEEK disks offer a balance between torque, torsional rigidity, and environmental compliance. Aluminum oldham coupling hubs are lightweight, cost effective, and offer low bearing loads. Stainless steel oldham couplings can be used in corrosive, cleanroom, and vacuum environments when paired with a PEEK disk. This combination is useful for motors in food processing applications. The multitude of standard options makes oldham couplings a good starting choice for motor manufacturers or integrators that package systems with lead screws, ball screws, or gearboxes. The same base oldham coupling hub can be specified with the motor while the disk and second hub change depending on the joined component.

Ruland manufactures oldham coupling in our Marlborough, MA factory with bore sizes ranging from 1/8” to 1-1/8” and 3mm to 30mm. They are zero-backlash when used with an acetal or PEEK disk.
