The U type is the basis for all Uniflex couplings. It is a shaft-to shaft- flexible coupling with a simple one piece design, making it ideal for indexing, robotic or positioning applications. The U type consists of a triple-wound flexible steel spring brazed to a steel hub at each end. This all steel design ensures optimum equipment protection in severe environments and/or high temperature applications. Lovejoy does NOT recommend the re-boring of uniflex couplings by customers due to potential damage to the brazed joint.
