Опорное кольцо гидроцилиндра Caterpillar 4979931

The Hydraulic Cylinder Backup Ring acts as a backup to prevent the seal from being forced out of its groove under extreme operating pressures and loads. It works by providing an additional barrier against fluid leakage. When the primary piston seal is subjected to high pressure, the backup ring helps to distribute the load and prevent the seal from being extruded or damaged, ensuring the integrity of the hydraulic unit.Attributes:• Maintain the effectiveness of the primary piston seal, reducing the risk of leaks• Ensure consistent performance across a wide range of operating temperaturesApplications:The Hydraulic Cylinder Backup Ring helps to protect the primary seal from wear, abrasion, and extrusion. It withstands higher pressures than the primary seal alone, allowing the system to operate safely under more demanding conditions.
