what is the function of oil seal

Front hub seals are designed to create a barrier between the external environment and the internal components of the hub assembly. They help to keep lubricants inside while preventing external contaminants from infiltrating the bearings. This is vital because wheel bearings rely on grease or oil for lubrication, and any ingress of dirt or water can lead to premature wear, overheating, and ultimately, bearing failure.

High-pressure oil seals are specifically engineered to withstand elevated pressures that are common in many industrial settings. These seals feature reinforced designs, which may include additional radial or axial support to help manage the stresses of high pressures. The materials used in high-pressure seals also play a crucial role; they must be able to maintain their integrity and elasticity under extreme conditions, resisting deformation and fatigue over time.

3. Backup Rings These are used alongside the seals to support them and prevent extrusion, especially in high-pressure situations.

1. Prevent Leakage By creating a tight seal around the shaft, oil seals effectively prevent lubricants from leaking out, which is essential for the efficient operation of machines.

1. O-Rings These are torus-shaped seals that are widely used due to their simple design and versatility. They can be used in dynamic and static applications, and their effectiveness depends on the material and size.
