The Service Brake Backup Ring enhances sealing effectiveness by providing secondary pressure containment behind primary seals. Its purpose is to act as a secondary barrier against hydraulic fluid leakage, particularly under high-pressure conditions during braking. Positioned behind primary seals, this ring provides additional support and resilience, helping to maintain a tight seal and prevent fluid escape, which could compromise brake performance and safety.Attributes:• High-pressure resistance.• Abrasion resistance.• Resistant to deformation under high loads.• Resistant to hydraulic fluid degradation.• Retains elasticity over extended periods of use.• Resistant to wear from repeated movements.Applications: The Service Brake Backup Ring serves as a secondary seal, installed alongside primary sealing elements, to enhance the integrity of the brake system, prevent hydraulic fluid leakage, and maintain consistent brake pressure during operation.
