In general, a ring is a circular component used in mechanical assemblies, often for sealing, retaining, or positioning parts. In hydraulic equipment, rings are commonly associated with piston-type components, but the exact function and construction of this specific ring should be confirmed against the catalog.
Please use part number 0306120 when requesting this ring. Before ordering, check the recorded catalog associations and confirm that the listed conditions match your machine's model, serial number range, and assembly, since the catalog does not establish compatibility for every configuration.
