The Lovejoy Jaw Coupling with Flexible Rubber Spider Insert (L-100) is a high-performance coupling designed for power transmission between rotating shafts in mechanical systems. It consists of two metal hubs and a flexible rubber spider insert that fits between them, allowing for misalignment compensation and vibration dampening. The L-100 model is ideal for pumps, compressors, conveyors, and general industrial machinery. The rubber insert enhances performance by reducing noise, absorbing shocks, and extending equipment life.The Rugged Made 3-piece flexible jaw coupling assembly replaces hubs on various industrial power transmission applications such as log splitters, compressors, blowers, pumps, conveyors, mixers, and gear boxes, among others. Flexible couplings are used to link two rotating shafts to transmit the rotational power. When being used on power equipment such as a log splitter, this complete coupler assembly & elastomer will create the connection between the engine and hydraulic pump.
