Rotary oil seals-Wear

Failure mode

Strong wear at the seal lip edge with 

appearance of grooves in the mating surface

Failure cause

wrong or too rough shaft surface (unsuitable 

system hardware / seal)

too high operating pressure

lack of lubrication

Remedial measures

follow surface recommendations

change shaft coating 

change of sealing profile

improve lubrication

Failure mode

strong wear at the seal lip edge

Failure cause

too high operating pressure

overload by frictional heat

insufficient lubrication

Remedial measures

use of wear resistant seal material

reduce operating pressure

use of high pressure oil seal

improve lubrication
