The radial load of elastomeric radial lip seals decreases with increasing temperature due to thermal expansion. The temperature coefficient describes this decrease assuming a linear correlation. The temperature coefficient has the unit Newton per Kelvin. A value of 0 corresponds to a constant temperature-independent radial load. In order to determine the temperature coefficient, the radial load has to be measured at different temperatures. Further details can be found in the Manual .

The 3 Guembel coefficients are used to describe the friction behaviour of the sealing system mathematically. An empirical relation between the coefficient of friction and the so called Guembel number is used. The frictional behaviour of a sealing system is influenced by many factors and can vary widely. The standard values for the Guembel coefficients that are stored in InsECT were experimentally determined using a radial lip seal made of FKM running on a plunge-ground steel shaft using a mineral oil. In order to achieve a precise prediction of the contact temperature, the frictional behaviour (that means the 3 Guembel coefficients) must be determined experimentally.
