The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal.

The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
