Oil Seals (Rotary Seals)

Oil seals (also known as rotary seals or shaft seals) cover a wide range of applications ranging from domestic equipments to automotive and power plant machinery, industrial pumps, gas and aircraft turbines and compressors.

If yours is a modern system, the surface speed can go up to 30 m/s and operating temperature can be as high as 250 degree Celcius. For these type of oil seals, our general purpose high performance oil seals can be employed. When the speed is increased up to 90 m/s, the lip will be produced using PTFE based compound to reduce heat generation. For high pressure applications, we offer a wide range of oil seal profile made using PTFE based compounds.

Here at Advanced Sealing Devices, we make and design reliable oil seals for your demanding tasks. If the oil seal is not selected properly, then even a few percents of leakage can be inconvenient and incur expenses to a large number of users, as well as cause environmental pollution. Note that the oil seal is not only to seal lubricating oil, it can also be used to seal other fluids such as water, foodstuff and chemicals. We understand that the reliability and reputation of your system depends on the well functioning of these oil seals.

Standard oil seals operate in a splash environment with no pressure or little pressure as low as 0.3 – 0.5 bars. If you have a higher pressure requirement, contact us and we can provide you with a different type of oil seal design. If a standard type of oil seal is used in a high pressure situation, lip distortion and wear will occur. This will shorten the lifespan of the oil seal and create unnecessary downtime. If your housing tolerances are not controlled as closely as standard housings, we can make the outer casing of oil seals with special profile so that the oil seals can seat properly in your housing before the assembly press tool is removed.

If you application is such that the lubricating liquid is not continuously available, or the operating temperature, fluid compatibility, the speed and pressure are of a more demanding nature, then we can make oil seals using stainless steel outer casings with various pure and filled PTFE lips (type ASD SS-PTFE). This type of oil seal is now widely used by our customers in the automotive and transmissions industry. A stainless steel casing with a PTFE lip oil seal will support more highly rated machinery and allow longer oil change intervals. Our ASD SS-PTFE type is particularly suitable for dry running application, for example, an engine may run dry for some period during startup until oil splash is available especially after a long period of storage or transportation. There are certain design aspects that are required in your system before using our ASD SS-PTFE type oil seal; contact us and we will advise you on this aspect. The following are some examples of stainless steel oil seals we make for our customers.

Beside oil seals, we can also make sealing devices which seal on the radial face of your system, as opposed to the axial face for oil seals. With this type of seals, your shaft surface finish can be less critical and the seals can operate with minor runout and misalignment.

Various Types of Precision Oil Seals

In making oil seals, we employ modern polymeric seal materials and we rely on our good understanding of the sealing mechanism that occur at the sealing interface. We will thus provide you with reliable oil seals and also to enhance protection of the environment. We offer the following types of oil seals:
