Back up seal for Terex RC45

The back up seal, part number 02-540-084-0000, functions as a support component within hydraulic sealing systems. It is installed alongside primary seals, such as O-rings or rod seals, to prevent them from extruding or deforming when the system is subjected to high operating pressures. By providing this structural reinforcement, the component ensures that the primary seal remains correctly positioned within its groove, maintaining the overall integrity of the hydraulic circuit.

This component is compatible with the Terex RC45 aggregate processing equipment. It is used in hydraulic cylinders and other critical sealing points throughout the machine where fluid containment is required. The part is manufactured to precise dimensions to ensure a proper fit within the seal housing, which is necessary for the effective operation of the primary seal under load.

Back up seals are used in hydraulic machinery to protect primary seals from the mechanical stresses caused by high pressure. By filling the clearance gap between moving parts, the back up seal prevents the primary seal from being forced into the gap, which would otherwise lead to premature seal failure and subsequent hydraulic fluid leaks.
