50High pressure rotary shaft seal
Radial and axial shaft seals are sealing rings made of elastomer and / or PTFE materials, with or without metal inserts and reinforced springs, which are suitable for shafts with relative rotational motion. It is mainly used for transmission system, shaft, agricultural machinery and construction equipment, compressor and pump, mixer, robot, reduction motor, etc.
Rotary seals are widely used to prevent any leakage or any medium exchange (viscous, liquid and gaseous), contain pressure, and eliminate any dust, moisture and dirt pollution between two chambers affected by relative rotation or swing motion. However, the main sealing function is only one of the necessary conditions for an effective and reliable radial shaft seal, because other functions are also essential.
Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.
Due to the almost universal chemical resistance of PTFE compounds, seals with PTFE sealing lip are particularly suitable for use with chemical, aggressive and corrosive media, pharmaceutical products, various coolants, synthetic oils, heat transfer oils, water and steam.
It is used in rotary or motion rod, rotary connector and transmission shaft working condition. ZHP type rotary seal has one or two round lubricating groove.
