Diagram of the radial shaft seals temperature

Permissible speeds in a pressure-free state according to DIN 3760

Sealing lip temperature is the mean temperature increased by the temperature caused by the friction heat. The higher the effective working temperature, the faster the aging of the elastomer will be, thus affecting the performance of the sealing lip and the shaft. Friction heat depends on the design and the material of the seal, peripheral speed, sealing lip preloading spring force, the design of the shaft and surface finish, lubrication, medium, etc.
