Stating the highest and lowest operating temperatures for a wiper seal of a particular type of material or, in some cases, combination of materials is very complicated. A number of factors affect each other. The graphic composition provides general guidance regarding the operating temperature ranges for different types of regular design wiper seals, and under otherwise normal operating conditions (diagram 1).
During normal use and installation, the respective materials provide satisfactory results within the temperature ranges shown in each column. Problems could begin to arise within the marked areas. Other materials should be chosen for use beyond these limits. Please contact SKF for further information.
