114-0711: 150mm Outer Diameter Backup Ring

A Backup Ring is used to hold an elastomeric seal or plastic seal in its desired shape and its correct place. Using Backup Rings allows O-rings to be utilized in high-pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Attributes: • Manufactured to precise specifications and are built for durability, and reliability • Distributes the load more evenly across the seal, reducing the stress Applications: A Backup Ring is used in a Hydraulic cylinder to act as a mechanical barrier that supports and reinforces the seal, preventing it from being forced into the clearance gap between the cylinder components.
