          Floating seal the shaft surface dirty, dust particles adhering penetrated oil seal lip wear shaft surface; invasion foundry sand, the wear surface of the shaft; external intrusion of dust, wear shaft surface; lubricant deterioration, generate oxides, invade the oil seal lip, floating seal wear shaft surface to ensure the shaft surface and seals and other clean; in order to prevent external intrusion of dust, dustproof device; use high-quality lubricants

            Floating seal shaft surface craft of cracking or corrosion points, increased wear and leakage; shaft surface scars, blisters and other lip seal formed between the gap and leakage; shaft surface scratches or bumps to ensure the quality of the shaft surface, cut Do not bump

          Floating oil left on the surface of fine threaded shaft ducts turning or grinding marks, forming pumping action and leakage

            Ensure shaft surface finishing processes. Experience has shown that: a small glass ball with a diameter of 0.05mm of the best shot peening

          "Critical Film" at the presence of the seal edge, seal edge to reduce wear and increase seal life is very useful, especially when several seals used in parallel, should pay special attention to lubricants (fat) supply, otherwise, the formation of dry friction due to lack of oil, resulting seal is burned, generally used in lithium grease best. To ensure clean grease, fats and oils and remove accumulated impurities or other harmful impurities, it is important to periodically replace the grease. Therefore, from the structural design, you must leave the filling hole and drain hole to prevent oil seal chamber temperature rises, sometimes it is important to open the vent.
