- Moreover, oil seals improve the reliability and safety of motors. Proper lubrication ensures that the motor operates at optimal temperatures, reducing the risk of overheating and potential fires. Furthermore, well-lubricated components are less likely to break down unexpectedly, reducing the likelihood of accidents or equipment failure during critical operations. This is particularly important in industries such as manufacturing, transportation, and power generation, where motors play a crucial role in daily operations.


Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
Some disadvantages of NBR are poor ozone, sunlight and weather resistance as well as limited high temperature and flame resistance. For higher temperature resistance, a much better material to use is Silicone.
Smear a little gasket sealant round the cover flange and fit the new gasket to it. Make sure it is flat and straight.

a7tc spark plug. With a simple screw-on design, most motorbike owners can replace their spark plugs in just a few minutes, without the need for specialized tools or professional help.
Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.
Metal cased design

Nitrile rubber offers good durability for general use, while the flexibility of the spring behind the sealing lip keeps the oil seal firmly in place against the moving part.
