An overview of the different standard types of oil seals and their main characteristics is shown below.
Conventional oil seals
Heat resistance
The interaction of the integrated seals with the shaft follows the dynamics of the PTFE seals. Often an additional dust seal (rubber lip or felt strip) provides an effective barrier against contaminating particles.
Oil seal type or shape
Friction modifiers: Friction modifiers help reduce friction when your engine is operating under high temperatures and with heavy loads. This additive can also help you maximize your fuel efficiency.
