Back-up ring for Terex HC230

This back-up ring, part number 0782 260 18, serves as an auxiliary component within the hydraulic sealing systems of the Terex HC230 crane. Its function is to provide mechanical support to O-ring seals, particularly in applications subject to high hydraulic pressure. By providing this support, the ring prevents the O-ring from extruding or deforming into the clearance gap between mating surfaces, which helps maintain the integrity of the seal and prevents fluid leakage within the hydraulic circuits.

The component is compatible with the Terex HC230 crane. It is utilized in various hydraulic assemblies where maintaining pressure is necessary for the operation of cylinders and valves. The part is manufactured by Terex.

In hydraulic systems, back-up rings are positioned alongside O-rings to manage the forces exerted by pressurized fluids. They ensure that the primary seal remains in its correct position and shape, which is necessary for the consistent operation of heavy machinery hydraulic components. Proper installation of these rings supports the overall sealing performance of the system.
