Back-up ring for Terex TX760B

This back-up ring, part number 378547X1, is engineered for use in the bucket cylinder assembly of the Terex TX760B loader. It is a critical component within the hydraulic system, positioned to support dynamic seals such as O-rings. By reinforcing the seal, it prevents extrusion and deformation that can occur under the high-pressure conditions typical of loader hydraulic operations.

The component is compatible with the Terex TX760B model. It is designed to maintain the integrity of the hydraulic cylinder, helping to prevent fluid leakage and ensuring consistent operation of the bucket mechanism.

In hydraulic systems, a back-up ring serves to bridge the gap between mating surfaces, providing a rigid wall that prevents the primary seal from being forced into the clearance gap. This support is necessary for maintaining the seal's shape and function when the system is subjected to significant pressure cycles. Properly functioning back-up rings are necessary for the overall reliability of hydraulic actuators.
