A Backup Ring is an integral component used in conjunction with a hydraulic cylinder rod seal to provide effective sealing. It is positioned along with the rod seal opposite to the fluid pressure and provides radial support to the rod seal, preventing extrusion and maintaining consistent sealing contact with the cylinder rod.Attributes:• Helps to reduce the friction between the sealing components• Prevents the rod seal from coming into direct contact with abrasive particles Applications:A Backup Ring acts as a mechanical barrier and helps to distribute the fluid pressure evenly across the sealing surface, reducing the risk of seal failure and leakage within the hydraulic cylinder rod.
