A Bucket Cylinder Backup Ring is used to prevent the leakage of hydraulic fluid from the cylinder's sealing unit. It achieves this by providing additional support to the primary sealing elements, thereby enhancing their sealing capabilities. By acting as a mechanical barrier, the backup ring minimizes extrusion and maintains the integrity of the seal under high-pressure conditions.Attributes:• Helps to ensure a tight and secure seal• Withstands constant movement, high pressures, and extreme temperaturesApplications:A Bucket Cylinder Backup Ring serves as a protective barrier, enhancing the sealing performance of the cylinder by providing additional support and ensuring the integrity and reliability of the unit.
