Back-up ring for Grove TMS-760

The back-up ring is an auxiliary component in hydraulic sealing systems. It sits behind primary seals, such as O-rings or piston seals, to prevent the seal material from extruding into the clearance gap between mating parts when the system is under pressure. By providing this mechanical support, the ring helps maintain the integrity of the seal assembly and prevents fluid leaks within the hydraulic circuits of the machine.

This component is specifically designed for the Grove TMS-760 truck-mounted crane. Proper fitment and dimensions are necessary to ensure the ring functions correctly within the specific cylinder or valve assemblies of this crane model. It is intended to be used as part of a standard seal kit during maintenance or repair of the hydraulic system.

Back-up rings are generally used in any hydraulic application where high pressures could cause a softer primary seal to deform or extrude. They are typically made from harder materials than the primary seal to provide the necessary resistance against the pressure forces encountered in hydraulic cylinders, pumps, and control valves. Using the correct back-up ring is standard practice when servicing hydraulic components to ensure the primary seal remains effective throughout its operational cycle.
