Oil seals, also known as rotary shaft seals, are a type of gasket used to prevent lubricant leakage and contamination in rotating machinery by creating a barrier between the moving and stationary parts.
When it involves a repair, you must first remove the old oil seal. To remove an oil seal, it is important to use the right tools to avoid damaging the shaft and bore. The best solution is therefore to pull out the oil seal without having to completely dismantle the shaft. This can be done by making a few holes in the oil seal with an awl and a hammer. You can then use a hook to pull the oil seal out of its seat. You could also screw some screws into the holes and then slowly pull out the screws to extract the oil seal from its housing. Be careful not to damage the shaft or housing in the process.

- Understanding these percentages is critical for engineers and technicians when selecting the right oil seal for a specific application. The balance between rubber, metal, and fillers determines the seal's ability to perform in diverse conditions, resist leakage, and endure mechanical stress.

5. TYPES OF FLUID: Numerous oil seals can interact with oils, fuels, grease, water and more. However, know exactly what type of fluid the rotary shaft seal will be in contact with will ensure the longevity of the seal and the machinery.
Developments and issues
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.
