- PTFE Oil Seals – Are a relatively new oil seal, the use of polytetrafluoroethylene means they can withstand dry and unlubricated operations. They have a massive thermal range spanning from -130°C to more than 200°C and a strong resistance to chemicals, they are the future of rotary shaft seals.
6. AMOUNT OF LUBRICANT: Seals perform better when lubricated but some machines will go through some dry spells. When this occurs using a leather or PTFE seal will be more beneficial as those type of seals can operate with less lubrication.
Assembling the oil seal
Usually, these oil seals are used to seal lubricating oil or grease and contain it within the application, so that moving parts such as bearings are continually supplied with enough lubrication. However, such seals are also used for sealing other liquids, gases, and solids, such as powders or granules.
