Rotary Thermoplastic Seals-Abrasion influence-deformation

Failure mode

deformation and cracking of seal

Failure cause

pressure overload

insufficient seal material

Remedial measures

use high strength seal material

use material with lower coefficient of 

friction

support seal

Failure mode

deformation

Failure cause

overheating due to friction heat generation

loss in material structure

Remedial measures

improve lubrication

change to pressure compensated seal designs
