Опорное кольцо наружным диаметром 305 мм Caterpillar 6363709

The Back-Up Ring is used to provide support and reinforcement to the primary seals. They prevent extrusion and damage of the primary seals when the hydraulic system operates under high pressures and extreme conditions. By acting as a barrier, backup rings enhance the sealing efficiency of the hydraulic cylinder, reducing the risk of leakage and maintaining optimal performance over timeAttributes:• Resistance to twisting and distortion.• Withstands rapid pressure changes.• Built with high-strength materials.• Corrosion resistant for longevity. Applications: The Back-Up Ring is placed directly behind the primary sealing element, such as an O-ring and piston seal in the hydraulic cylinder assembly to prevent extrusion and damage to the primary sealing element under high-pressure conditions
