The back-up ring, part number 0758 719 12, serves as a support component within the hydraulic and pneumatic circuits of the Terex HC230 crane. It is installed alongside primary seals, such as O-rings, to prevent them from deforming or extruding into the clearance gaps between mating surfaces when the system is under pressure.
This component is compatible with the Terex HC230 model. By providing a rigid surface that limits the movement of the primary seal, the back-up ring helps maintain the integrity of the seal assembly during operation.
In heavy machinery, back-up rings are used to protect sealing elements from damage caused by high-pressure hydraulic fluid. By filling the gap between moving parts, they ensure that the primary seal remains in its correct position, which is necessary for maintaining system pressure and preventing fluid leakage in cylinders and valves.
