One common type of oil seal is the lip seal, also known as radial shaft seal. This type of seal consists of a flexible lip that fits tightly against the shaft, preventing the oil from leaking out. Lip seals are typically made from rubber or elastomeric materials, which provide a good seal and resistance to oil and other fluids. They are commonly used in engines, gearboxes, and hydraulic systems.
