The Backup Ring is placed between the piston and cylinder head, providing a rigid and stable surface to support the sealing components. During operation, the backup ring helps to distribute the high pressures and forces exerted on the seals, preventing deformation or damage and ensuring the seals maintain their sealing capabilities over the long term. It serves as a backup and support structure for the primary sealing elements, ensuring the integrity of the unit.Attributes:• Minimizes the wear and tear on the sealing components during the operation• Resistance to a wide range of hydraulic fluids, lubricants, and other chemicals, ensuring compatibility with the operating environmentApplications:The Backup Ring is used in the boom cylinder, bucket cylinder, stick cylinder, and clam cylinder. It provides support and protection for the primary sealing elements, preventing deformation and ensuring the seals maintain their sealing capabilities.
