542-9983: 253.50mm Inner Diameter Backup Ring

The Backup Ring is to provide support and prevents extrusion or deformation of the primary sealing element, especially in the hydraulic cylinder. It acts as a mechanical barrier that helps maintain the integrity of the primary seal, ensuring a more reliable and effective seal in challenging operating conditions. It provides the main sealing function by preventing fluid leakage between the moving components of the cylinder, such as the piston and cylinder bore. Attributes: • Prevents extrusion or deformation of the primary seal • Provides a barrier against high-pressure forces • Ensures reliable and leak-free operation • Reduces wear and seal damage Applications: This Backup Ring is located where the primary seal, such as an O-ring, is used to prevent leakages.
