The back-up ring, part number 0758 719 17, is a component used within the hydraulic assemblies of the Terex HC230 crane. It is installed alongside dynamic seals, such as O-rings, to prevent the seal from extruding into the clearance gap between metal surfaces when the system is subjected to high pressure. By providing a rigid support structure, this ring helps the primary seal maintain its shape and sealing effectiveness during operation.
This component is specifically compatible with the Terex HC230 model. It serves as a critical element in maintaining the hydraulic integrity of the machine by ensuring that seals remain properly seated and functional. Proper installation of this back-up ring is necessary to prevent fluid leakage that can occur when seals are unsupported under load.
In heavy machinery, back-up rings are used in various hydraulic cylinders and valves where high-pressure differentials exist. Their function is to bridge the gap between mating components, thereby protecting the softer sealing elements from deformation or damage caused by hydraulic pressure forces.
