• SIM method to prevent the spring from falling off (integral molding of spring and rubber)
- Radial lip seals are the most common type of oil seal used to prevent leakage of fluids such as oil or grease in rotating machinery. They consist of a metal outer casing with an elastomeric sealing lip that is pressed against the shaft to create a tight seal.
- In conclusion, while the upfront cost of spark plugs may seem insignificant, their cumulative impact on vehicle health and maintenance budgets is considerable. Proper care and timely replacement of spark plugs protect against more severe engine damage, ensuring that vehicles run efficiently and last longer. By understanding the full scope of spark plug costs, vehicle owners can make informed decisions to keep their cars running smoothly and economically.
Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.

What is Oil Seal
What should you take into account when selecting an oil seal? Different types of oil seals and various types of materials are available, each designed for specific uses. It is also important to select the right size of oil seal for the best results. For this reason, selecting the right oil seal requires adequate understanding of the application in which it will be used.

Materials Used to Make Oil Seals
Rotary shaft or oil seals are placed between moving and stationary pieces of machinery to ensure that contaminants, moisture, corrosive materials and abrasives do not damage the various components. They can also prevent unwanted mixing of fluids, including water and oil combining within a machine.

Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.
