Back-up ring for Terex HC230

The back-up ring 0762 136 35 serves as a critical component in the hydraulic sealing assemblies of the Terex HC230 crane. It is engineered to work in tandem with a primary seal, such as an O-ring, to provide necessary mechanical support. By reinforcing the primary seal, it prevents the material from extruding or deforming into the clearance gap when the system is subjected to high hydraulic pressures. This support is vital for maintaining the integrity of the seal and preventing fluid leakage within the machine's hydraulic circuits.

This component is compatible with the Terex HC230 model and is designated by the specification G135-T3. It is intended for use in various hydraulic applications, including cylinder assemblies, valves, and other pressurized fluid connections found throughout the crane. During routine maintenance of hydraulic systems, back-up rings are typically replaced alongside primary seals to ensure the continued functionality and pressure-holding capacity of the assembly.

In hydraulic systems, a back-up ring acts as a structural stabilizer for softer sealing elements. By filling the extrusion gap, it allows the primary seal to operate effectively under higher pressure ratings than it could withstand on its own.
