Back-up ring for Terex HC230

The back-up ring with part number 0752 694 11 acts as a mechanical support component within the hydraulic sealing systems of the Terex HC230 crawler crane. It is positioned adjacent to primary seals, such as o-rings or piston seals, to prevent them from deforming or extruding into the clearance gaps between mating surfaces when subjected to high pressure. By providing this support, the ring maintains the structural integrity of the primary seal, ensuring the hydraulic system operates effectively without fluid leakage.

This component is specifically designed for use in the Terex HC230. It is utilized in hydraulic cylinders, valves, and other pressurized assemblies where maintaining a consistent seal is necessary for machine operation. The part is manufactured to meet the technical requirements of the Terex HC230 hydraulic system.

In general engineering, a back-up ring serves to bridge the gap between moving parts in a hydraulic assembly. By limiting the movement of the primary sealing element, it allows the system to withstand higher pressure cycles than the primary seal could manage on its own. This component is a standard element in high-pressure hydraulic circuits to ensure long-term sealing performance.
