The lip is specially designed to ensure the oil seal works effectively with the different forces that arise during rotation. Many different designs and materials are used, so countless types of oil seals are available. These are chosen according to the application; pumps, gearboxes, wheels, and many other rotating applications where fluids need to be sealed. They are used in a variety of sectors, such as the chemical industry, manufacturing, wind turbines, automotive sector, food industry, and more. Oil seals are used in nearly all sectors.
Among the different types of oil seals available, the 25, 35, and 70 oil seals are some of the most commonly used sizes. These seals are designed to fit shaft diameters of 25mm, 35mm, and 70mm respectively, providing a secure and tight seal to prevent leaks.
These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
A patent for an oil seal was filed by Nelson Thomas Edward on August 12, 1937, and published a year later. There were two purposes described. The device was to provide an oil seal between a fixed housing and a rotating part. The seal is described as
1. Automotive industry NBR oil seals are used in engine seals, transmission seals, differential seals, and power steering seals.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.
Despite these benefits, die-cut silicone gaskets are relatively lightweight and easy to install, reducing production downtime and simplifying maintenance processes. Their versatility allows them to be customized in terms of thickness, hardness, color, and shape, making them adaptable to a wide range of applications.1. Pressure: Many oil seals are used in high-pressure applications, so understanding the working pressure of your components is very important.
Oil seals can offer:
