- In addition to thermal stability, die-cut silicone gaskets provide excellent chemical resistance. They can endure exposure to oils, acids, alkalis, and many other chemicals without degrading, ensuring a long service life. This characteristic is particularly valuable in chemical processing and pharmaceutical industries where exposure to harsh substances is common.
The shaft surface to be in contact with the lip should be finished to
0.1 to 0.32 μmRa and 0.8 to 2.5 μmRz
and the lead angle to no greater than 0.05°. (There is a risk that the lead marks will impede the sealing performance of the oil seal: see Figure 5.)

Choosing Quality Oil Seals for Wheel Hubs and Steering Mechanisms

The construction of an oil seal is a testament to meticulous engineering. Each oil seal primarily comprises two core components: the sealing element and the metal case. The collaboration of these parts brings about the seal’s functionality and effectiveness. A garter spring may also be included as an available feature, providing an extra layer of operational support.
