Back-up ring for Terex HC230

The back-up ring, part number 0751 171 22, serves as a support component within the hydraulic and pneumatic assemblies of the Terex HC230 crane. Its primary function is to provide structural backing to dynamic seals, such as O-rings, which helps prevent them from extruding or deforming when subjected to high operating pressures. By effectively limiting the clearance gap where the seal material might otherwise flow, this component assists in maintaining the integrity of the sealing system and helps prevent premature fluid leaks. This part is manufactured by Magrumape.

This component is specifically compatible with the Terex HC230 model. It is intended for use in high-pressure applications such as hydraulic cylinders and control valves where maintaining precise tolerances is necessary for system performance. Proper installation of a back-up ring is essential for the function of dynamic seals in environments where clearances between moving parts are minimal. By ensuring that seals remain correctly positioned and supported, this ring helps maintain the overall operational efficiency of the machine's fluid power systems.
