Ruland Manufacturing (Marlborough, MA) offers its Oldham couplings, which have typically been used in motion control applications where zero-backlash performance is needed. However, according to the company, the couplings can be used as an alternative to straight jaw couplings on general industrial equipment such as pumps, valves, gearboxes, and conveyor systems. The three-piece assembly is comprised of two anodized aluminum hubs and a torque-transmitting center disk, and the system helps extend life if misalignment is present. In addition, the Oldham couplings promote a light bearing load, stop transmission of power during overload, and minimized damage to expensive machinery components.
