This Lovejoy curved jaw coupling spider replaces the spiders on Lovejoy curved jaw style flexible spider coupling assemblies and is made of urethane for transferring and absorbing shock load. This center element, also known as a spider, absorbs shock and misalignment within the coupling assembly for reduced wear on the shaft assembly. Lovejoy curved jaw style couplings are a type of flexible coupling suitable for use in various industrial power transmission applications such as compressors, blowers, pumps, conveyors, mixers, and gear boxes, among others.
