Abstract
Modern lubricants (e.g. polyglycols, esters) cause problems when sealed with rotary shaft
seals. The wear of rotary shaft seals strongly depends on the wetting properties of the respective friction partners. The paper shows, how the susceptibility to wear of rotary shaft sealing
systems can be estimated by a combined consideration of the wetting properties of the sealing
components, the lubricants viscosity and the pumping rate of the sealing system. Investigations were carried out using polished steel counter faces made from eight different alloys,
together with FKM rotary shaft seals and eleven chemically different lubricants (mineral oils,
polyglycols, poly-α-olefins, esters and silicone oils).
