The back-up ring, identified by part number 45Z568D2, serves as a support component within the hydraulic and mechanical systems of Terex cranes. It is installed in conjunction with a primary seal, such as an O-ring or lip seal, to prevent the seal from extruding or deforming when subjected to high pressure. By providing a rigid support surface, this component maintains the structural integrity of the sealing assembly, which is necessary to prevent hydraulic fluid leaks and ensure consistent system pressure.
This component is compatible with various Terex crane models. It is manufactured to meet the specific requirements for fitment within hydraulic circuits where seals are at risk of extrusion. Proper installation of this ring is necessary to support the sealing system during the high-load operations typical of industrial cranes.
In hydraulic systems, back-up rings are used to bridge the gap between mating surfaces, preventing the primary seal from being forced into the clearance space. This support allows the primary seal to maintain its shape and function effectively, extending the service life of the sealing assembly and preventing fluid loss in pressurized circuits.
