Back-up ring for Grove RT635C

The back-up ring 9926105653 serves as a support component within the hydraulic systems of the Grove RT635C rough-terrain crane. It is positioned adjacent to the primary seal, such as an O-ring, to prevent the seal from extruding into the clearance gap between mating surfaces under high operating pressures. By providing this rigid support, the component helps maintain the integrity of the seal and prevents fluid leakage within the crane's hydraulic cylinders, valves, and pumps.

This component is specifically engineered for the Grove RT635C crane model. It is designed to fit precisely alongside the primary sealing element to ensure proper operation of the machine's hydraulic actuators. The part is intended to be used in systems where high pressure is present, ensuring that the seal remains in its correct position during operation.

In hydraulic systems, back-up rings are used to extend the pressure rating of a sealing assembly. By filling the extrusion gap, they allow the primary seal to function effectively without deforming or failing under intense hydraulic force. This support is necessary for maintaining consistent pressure levels and preventing the premature failure of seals in heavy machinery.
