Back-up ring for Terex HC230

The back-up ring, part number 0762 125 35, functions as a support component within the hydraulic and pneumatic systems of the Terex HC230 crane. It is positioned adjacent to dynamic seals, such as O-rings or piston and rod seals, to provide structural reinforcement. By filling the clearance gap between mating metal surfaces, this component prevents the primary seal from deforming or extruding when subjected to high operating pressures. This support maintains the integrity of the sealing assembly and helps prevent fluid leakage during machine operation.

This component is compatible with the Terex HC230 crane model and is identified by the G35-T2 specification. Back-up rings are used in hydraulic systems to protect seals from damage caused by pressure spikes and mechanical clearances. By ensuring the seal remains in its proper position, the back-up ring allows the hydraulic cylinder or actuator to function correctly under load. Proper installation of this ring is necessary to maintain the sealing performance of the hydraulic circuit.
