One common type of high-pressure oil seal is the lip seal, which consists of a flexible lip that contacts the shaft, creating a barrier against fluid leakage. The design of the lip is critical — its angle, material, and groove shape all influence its ability to hold back fluids effectively. Furthermore, the surface finish of the shaft plays a vital role as well; a smooth, polished surface reduces wear on the lip of the seal, extending its operational life.

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.

Oil seals are specially designed sealing devices that fit into machinery to prevent the leakage of oil and other fluids while keeping contaminants like dust, dirt, and moisture out. Typically made from elastomeric materials, they exhibit flexibility, durability, and resistance to a wide range of temperatures and aggressive chemicals. Oil seals come in various shapes and sizes, tailored to fit specific applications and installation spaces.
