Back-up ring for Terex HC230

The back-up ring, part number 0752 083 50, serves as a support component within the hydraulic and pneumatic sealing assemblies of the Terex HC230 crane. It is engineered to fit specific sealing configurations where it prevents the primary dynamic seals, such as O-rings, from extruding into the clearance gaps between mating parts under high operating pressures.

This component is compatible with the Terex HC230 model. It functions by limiting the deformation of the primary seal, which helps maintain the integrity of the hydraulic system and prevents fluid leakage in cylinders and actuators. Proper installation of this ring ensures that the sealing system maintains its intended pressure capacity during crane operations.

In hydraulic systems, back-up rings are positioned adjacent to the primary seal to provide mechanical reinforcement. By preventing the seal from being forced into the gap between moving surfaces, the back-up ring allows the system to operate effectively under the high-pressure conditions typically found in heavy machinery.
