Oldham couplings are three-piece flexible shaft couplings that are used to connect driving and driven shafts in mechanical power transmission assemblies. Flexible shaft couplings are used to counter the inevitable misalignment that occurs between connected shafts and, in some cases, to absorb shock. Material: Uubs are in Aluminium, elastic body is in PA66.
