577-1407: 155.68mm Inner Diameter Service Brake Backup Ring

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.

• Material: Polytetrafluoroethylene (PTFE) Plastic
