What Materials Are Available for Oil Seals

图片
  An   oil seal   is also known as a rotary shaft seal, shaft seal, lip seal, elastomeric lip seal, or any variation of these. It is a simple device used to remove dust, dirt, water or any other contaminants while retaining the lubricant in a rotary shaft device. Often, it has been developed as a way to protect rotating shaft bearings. The following shows the selection of  oil seal materials ​. 1,  Aflas,  temperature range between -10°C and +205°C, made of special fluoroelastomer (FKM), resistant to steam, petroleum, amine corrosion inhibitors and hydrogen sulfide. 2, Carboxylated Nitrile , temperature range -55°C to +135°C. Carboxylated Nitrile seals are made of a low temperature resistant compound that also has excellent abrasion resistance. Resistant to water and oil, 3,  Viton , temperature range -20°C to +205°C, FKM fluorocarbon seals are highly resistant to solvents and petroleum oils. As a result, they are ideally suited for high temperature installations and have low compressi
