Опорное кольцо диаметром 170 мм Caterpillar 6426589

A Backup Ring is used to provide support to the seals under high pressure and dynamic conditions, where there is a risk of extrusion. By offering additional stability and resistance to deformation, the backup ring ensures a reliable and leak-free seal, thereby preventing fluid and gas from escaping the system. It provides an accurate fit with the O-ring, acting as a mechanical barrier against extrusion, abrasion, and wear, thus extending the service life of the sealing unit.Attributes:• Provides support to prevent seal extrusion and deformation under high-pressure applications.• Facilitates proper sealing by maintaining seal shape and integrity.• Provides a reliable barrier against fluid leakage.• Enhances sealing efficiency by maintaining consistent pressure.Applications:A Backup Ring is installed within the hydraulic cylinders to support primary seals prevent extrusion under high-pressure conditions and ensure reliable hydraulic fluid retention and smooth cylinder operation.
