Chemical resistance

Information about chemical resistance is provided in the table, regarding the resistance of SKF sealing lip materials to most of the substances encountered in industrial applications. The information is based on in-house testing and the experience of users, as well as information from the suppliers of the various materials. Unless otherwise stated, the information is valid for media of commercial purity and quality.
The chemical resistance of a seal is influenced by temperature, pressure and the amount of media present. Other important factors to consider when selecting a suitable sealing lip material include:
  • type of service (static or dynamic)
  • circumferential speed of the sealing lip
  • shaft and housing materials
  • surface finish of the seal counterface
Because the above mentioned factors also influence the service life and performance of the seal, the information contained in the table Chemical resistance can only be considered as a rough guide.
