Lovejoy L225 Jaw Coupling

The Lovejoy L225 jaw coupling connects two rotating shafts while accommodating minor parallel, angular, and axial misalignments in industrial drive systems through a design incorporating steel hubs and elastomeric elements. Built with machined steel hubs and an included elastomer spider element designated by the specification code A77, this unit transmits torque from power sources like electric motors to driven load side equipment including pumps, fans, and compressors. The specified 1-1/4 inch bore dimension ensures compatibility with matching shaft sizes, allowing secure installation via standard fasteners before engaging the mating hub across the coupling gap. By utilizing the resilient center element, the coupling absorbs mechanical shocks, dampens vibrations, and protects downstream components such as bearings and seals from excessive stress caused by dynamic misalignments during high-load cycles. Supported by versatile industrial configurations, this model facilitates scheduled maintenance where the worn element can be replaced without removing the hubs from the shaft, minimizing disruption to plant operations in settings ranging from hydraulics to material handling.
