Опорное кольцо с внутренним диаметром 130 мм Caterpillar 6426509

The Back-Up Ring in a hydraulic cylinder is used to support and protect sealing elements under high-pressure conditions. It prevents extrusion of the primary seal into clearance gaps, maintaining a consistent sealing surface. Positioned alongside O-rings or other seals, the back-up ring extends the operational lifespan of the sealing system. Its presence ensures that hydraulic pressure is properly contained, promoting reliable cylinder performance over time.Attributes:• Provides mechanical support to soft seals.• Reduces the risk of seal extrusion under pressure.• Enhances sealing integrity during pressure fluctuations.• Minimizes system leaks and maintenance needs.Applications: The Back-Up Ring is used within hydraulic cylinders to reinforce primary seals, helping them maintain contact and form a barrier against fluid escape. It ensures stable cylinder operation by reducing seal wear and supporting consistent pressure handling throughout the cylinder's service life.
