Oldham couplings include a variety of features to meet application demands. Keyways are standard to increase torque capacity of the coupling by creating a positive drive while ensuring precise positioning of the coupling hub. Hubs are available in stainless steel for corrosion resistance. Where frequent removal might cause discs to fall off, discs and hubs can be modified to allow them to be attached. Discs are also available with a center hole to allow shaft penetration. Special bores and lengths are offered as well.
These couplings are offered from stock in a choice of six outside diameters from ½ in. (13 mm) to 2-¼ in. (57 mm) in both set screw style and clamp style. A large variety of inch and metric bore sizes starting at 1/8 in. (3 mm) is available with keyways offered on 3/8 in. (8 mm) and larger bores.
