Before installing the oil seal, check the seal carefully for damage. Make sure there are no cuts or tears around the seal lip, which is the two layers inside the oil seal.
Another thing to consider is the outer diameter of the oil seal. Any damage detected prior to installation will make it impossible to use further.

For installation tools, make sure that they do not have any jagged edges that may damage the seal during the installation process.
3. The spring on the lip of the oil seal tends to provide support to the lip and prevents the lubricant from leaking outside and also prevents the entry of contaminants from outside.
A) Shaft runout
As shown in Figure 8, shaft runout is defined as being twice the eccentricity between the shaft center and center of shaft-center rotation trajectory.

Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.
These problems can be overcome through a better understanding of the types of sealing materials available, redefined selection procedures and the consistent application of sound replacement and maintenance practices.
3. Fluid types: Oil seals interact with oils, fuels, grease, water, and more. Choosing a seal material that is most compatible with your chosen medium can help to increase the durability of the seal and its internal components.
