All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.
Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.

These cassette seals are widely used in wheel-end applications, such as the axles of agricultural machinery or off-road trucks.
Improper installation can cause your oil seal to malfunction. While being tapped into place, it can become tilted or misaligned in the bore. That being said, setting it up correctly will help ensure that the sealing process is effective.

Even though it’s better than other materials in terms of toughness and wear time, it is preferably used in dry-running applications. The salient demerit of this material is its cost.
