Seal materials

SKF industrial shaft seals are generally manufactured from the materials listed in the table. These materials have characteristics that make them particularly suitable for specific applications.
By changing the actual formulation and blending, it is possible to modify the characteristics of the elastomers relative to:
  • resistance to swelling
  • elasticity
  • chemical resistance
  • thermal resistance
  • behaviour in the cold
  • gas permeability
Details about the chemical resistance of sealing lip materials to various media encountered in operation are provided in the section Chemical resistance.
