- The primary function of an oil seal is to create a tight barrier between two surfaces, one stationary and the other in motion. It achieves this by utilizing a combination of materials, including rubber, plastics, and metals, which are carefully selected for their compatibility with the operating conditions and the fluids being sealed.
1. Pressure: Many oil seals are used in high-pressure applications, so understanding the working pressure of your components is very important.
1. Oil seals have three basic components: sealing element, metal case, and spring.
Silicone Oil Seals - Designed to absorb lubricants in order to lessen wear and friction, silicone rotary shafts also offer high thermal resistance and a large temperature range. But, they do not handle abrasions well or interact with oxidized oils.

Table 3: Features of each seal type
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
In addition to its excellent temperature resistance, it is also resistant to ozone, light, and weather conditions. Silicone can be typically found in the food and medical industry as well as in hydraulics and pneumatics. It is often the preferred material for o-rings, moulded parts and flat seals but is also commonly used for electric insulators due to the material’s translucency and flexibility.
The pulley is kept from turning on the crankshaft by a key fitting into grooves on the crankshaft and pulley.
There are three main different types of headlights. These car headlights types are Halogen, Xenon & LED headlights. Each work quite differently in the way they produce light and therefore produce different types of light on the road.
