The back-up ring, part number 0762 135 70, serves as a support component within the sealing assemblies of the Terex HC230 crane. It is engineered to function alongside O-rings or other elastomeric seals to maintain system integrity. By providing structural support, this ring prevents the primary seal material from extruding into the clearance gaps between mating components when the system is subjected to high pressure.
This component is compatible with the Terex HC230 model. It is designed to support the sealing system under operational conditions where standard O-rings might otherwise fail due to pressure-induced deformation. The reference G70-T3 relates to the specific profile and design requirements for this application.
In hydraulic and pneumatic systems, a back-up ring acts as a mechanical barrier that allows the primary seal to operate effectively at higher pressure levels. By filling the extrusion gap, it ensures that the seal remains in its proper position, thereby maintaining the pressure containment required for the machine to function correctly.
