Опорное кольцо цилиндра стрелы, внутренний диаметр 105 мм Caterpillar 6426494

The Boom Cylinder Backup Ring serves as a support element for the primary seals, preventing extrusion and deformation when exposed to high pressure. This backup ring helps maintain consistent sealing integrity, ensuring hydraulic fluid remains contained and preventing leaks. It helps in reducing friction and minimizing wear enhances the efficiency of the hydraulic system, allowing smooth and reliable cylinder operation. Preventing premature seal failure, contributes to the extended operational life of the hydraulic boom cylinder and reduces maintenance requirements.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: The Boom Cylinder Backup Ring is installed within the hydraulic boom cylinder to support primary seals and prevent extrusion under high-pressure conditions and it ensures reliable hydraulic fluid retention and smooth cylinder operation.
