An oil seal is a type of mechanical seal used to prevent the leakage of oil from machinery components. The dimensions of an oil seal are usually specified in terms of its inner diameter, outer diameter, and thickness. For example, a 38x52x7 oil seal has an inner diameter of 38mm, an outer diameter of 52mm, and a thickness of 7mm.
Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.
Although extremely flexible, silicone does have some disadvantages. Many silicone compounds have poor tensile strength, tear resistance, and abrasion resistance. If you are looking for a material that offers a higher tensile strength, while still offering high temperature resistance, look no further than Viton®.

silicone rubber gasket. This resistance makes them suitable for use in industries where exposure to harsh chemicals is common, such as in the chemical processing, pharmaceutical, and food and beverage industries. The inert nature of silicone rubber also prevents it from reacting with the substances it comes into contact with, ensuring a long-lasting and reliable seal.

When installed, the oil seal’s flexible lip is placed against the rotating shaft, and the casing is pushed into the housing for support. It is crucial that the sealing lip is lubricated to avoid overheating caused by friction.
Oil seals, which are also known as rotary shaft seals, fluid seals or grease seals, play an important role in closing down the gaps between moving and stationary elements of mechanical equipment.
