A Backup Ring for a stick cylinder is a resilient, ring-shaped component crafted from durable materials like polyurethane or nylon. It is specifically designed for installation around the piston or rod of a hydraulic cylinder used in heavy machinery's stick or boom arms. This backup ring serves the vital function of providing an additional seal, protecting primary seals from wear, withstanding high hydraulic pressures, and preventing contaminants from entering the hydraulic system, thereby ensuring the reliability and longevity of the hydraulic cylinder.

Attributes:
• Handles high hydraulic pressures and temperature changes.
• Reduces friction for efficient cylinder operation.
• Ensures hydraulic system integrity and continuity.



Applications:
A Backup Ring is designed to ensure the continuous and efficient movement of the stick, ultimately supporting the overall performance of heavy machinery in operating conditions.
