In this paper, we conducted durability tests of V-seals to propose a new maintenance assessment method. V-seals are fiber-reinforced rubber components to seal the mechanical shaft from fluid. They are used at hydraulic power generator and abraded by rotating shaft. Durability tests were conducted by the device reproducing usage condition of the V-seals in the generator. After the durability test, V-seals were abraded intensely. Nevertheless, from the leak tests results, these V-seals had maintained high seal performance. Then leak tests of pre-cut V-seals were conducted. These V-seals are the ones that abraded state was imitated. From the tests results, the relation between wear volume and seal performance was clarified.
