The most important function of an oil seal is to protect all types of sleeves, roller bearings, and balls located in the rotary shafts. These seals also prevent two fluids from mixing, such as water and oil.

You have to consider the speed at which the shaft will be moving, the housing bore, and the runout. These are important to make sure that you choose an oil seal that will not be exposed to unconducive abrasions.

They are best known for their bright light emission that is far reaching. Their tungsten is encased in a quartz tube filled with xenon gas. They may require more power when turned on but use much less of it to maintain brightness. Moreover, they have a longer lifespan compared to the halogens. They may seem better but they also present some limitations such as being more expensive as far as manufacturing and replacement is concerned. They are not easy to manufacture from their complex design. Their bright light cause a blinding effect to oncoming traffic which is undesirable and can cause dangers on roads.

The square shape of the gasket allows for a more precise fit in square or rectangular openings, ensuring a tight seal to prevent fluids or gases from escaping. Made from high-quality rubber materials such as neoprene, silicone, or EPDM, these gaskets offer excellent resistance to temperature, pressure, and chemical exposure.

Most oil seals are designed to support very low-pressure (8 psi or less) applications. If at all, there will be additional pressure along the way, pressure relief should be put into play. This is why it’s important to know the characteristics of the oil seals you are considering and compare them with your application.

To increase the pressure around the shaft and maintain the seal’s integrity, certain lip seals have an extra spring looped into the flexible rubber part.
