Oldham couplings accommodate large amounts of parallel misalignment with light bearing loads. The three-piece design is comprised of two hubs and a floating center disc, which comes in acetal for high torsional stiffness or nylon for shock absorption and vibration dampening.
They also handle small amounts of angular misalignment and axial motion. The couplings have electrical isolation, mechanical fuse properties, and are relatively low in cost. They come in seven sizes of set-screw or clamp-style hubs, with bores from 1/8 in. (3 mm) to 2 1/4 in. (57 mm). The anodized hubs improve lubricity and increase life.
