Features of Caterpillar oil seal and PTFE/ VITON oil seal



Oil seals are generally used in crankshafts, driveshafts, and hydraulic cylinders to lubricate a rotating shaft by grease or oil. Although there are many branded oil seals out there, a Caterpillar oil seal is acknowledged for its unique features and top-notch performance. It works effectively like a cap, bridging the clearance between the housing and shaft, preventing fluid leaks, at the same time as preventing inhibitions from going into the chamber.


 If you have plans to replace a damaged part for the reason that you have identified a fluid leak, then choosing a Caterpillar oil seal is the cleverest as well as the most affordable option. This is for the reason that these oil seals are perfectly designed not only to offer the best performance. They are also designed to prevent all forms of fluid leaks for many years to come, besides improving the overall performance of your equipment.

Every oil seal from Caterpillar comes with a machinery handbook to make you find the right variety of oil seal you need. They come with the required guidelines to assist you to acquire the right seal for the job. 

The inside diameter nearby the rotating shaft is usually fixed with an energized sealing lip or garter spring. This will allow some give to avert an upsurge of friction. In the meantime, the external diameter has a safe fit with the static bore or housing. Therefore, the manufacturer suggests sizing the oil seal with a smaller inside diameter and wider external diameter.

When it comes to design, each Caterpillar oil seal comes with different designs according to your needs. However, the most commonly used design includes Type A, Type B, and Part C, each has its own specifications and uses. While the Type A oil seal comes with a fully enclosed elastomer, Type B features a partially enclosed elastomer. Part C oil seal comes with a partially enclosed metal unbreakable elastomer. As both Type B and Type C oil seals come with metal exposed on the top, they allow for a tighter forbearance. When it comes to Type C oil seal, it is available with an extra metal insert, which can be used in heavy-duty applications effectively.

The notable versatility of the PTFE/ VITON oil seal is that it can be used where several other materials and elastomers are incompatible with the application conditions, such as chemical resistance, friction, and temperature. These oil seals are used for an extensive variety of applications in numerous industries, including food and drink, aerospace, pharmaceuticals, semi-con, and telecommunications.

You can also use a PTFE/ VITON oil seal for flange chemical resistance or axial static faces. It is considered the most trusted and affordable of the O-ring materials. This is for the reason that these oils seals have immense resistance to many chemicals, including bases, acids, oils, and steam. They are extremely hard and abrasive resistant, as well, even at high temperatures.

If you would like to acquire an oil seal that has great resistance to chemicals and electricity, you can consider buying a PTFE/ VITON oil seal.

Know the uses of the Caterpillar oil seal and PTFE/VITON oil seal

Image
A Caterpillar oil seal is renowned for the effective prevention of the seepage of lubricating oil in mechanical equipment. These devices work resourcefully by closing the spaces between the static and dynamic components of the equipment. Oil seals are referred to as rubber oil seals, dirt seals, or oil gaskets, as well. Caterpillar oil seals are available with the highest quality as well as with the most durable construction. These features make them more useful and reliable in a variety of sealing applications, including in housings and gearboxes. These oil seals are capable of preventing the leak of non-pressure grease and fluids, as well. Normally, a shaft is rotating inside a bore or housing. There should be some clearance between the bore and the shaft due to friction. The job of the Caterpillar oil seal is to stop any type of the inside fluid from overflowing the clearance between the shaft and housing. The seal may be used to prevent exterior materials, as w
