Oil Seals

Oil seals are compression seals that prevent oil and other types of lubricants from escaping grease compartments in industrial machines. They are often used in hydraulic systems where lubrication and abrasion prevention are crucial for continuous operation. A hydraulic oil seal is an O-ring coated with a metal casing or spring. It prevents lubricants from leaking out and mixing with other liquids in adjacent parts of the machine.

Oil seals are designed to fit varying types of equipment. Oil seals are used in precision bearings and specific machine components. Hydraulic oil seals can be installed as static seals for non-moving machine parts or as dynamic seals for constantly moving machine parts. Aside from lubricant leakage prevention, oil seals also ensure that the mating parts of an assembly do not corrode. Metal corrosion can happen when aggressive chemicals mix with oil. The resulting mixture can lead to the formation of abrasive substances that accelerate corrosion. Oil seals prevent corrosion by ensuring that mating parts are totally sealed with compression. 

Many industries rely on oil seals for lubricant sealing and machine protection. Oil seals are pliable and tear-resistant compression seals, which are used in the automotive, oil, gas, energy, and manufacturing industries.

Oil seals are used for critical applications in industries such as oil, gas, and petrochemicals. They are designed to prevent leakage from the sealing lip and rotary shaft by creating a thin oil layer between them. Oil seals can be produced using well-known sealing materials including PolyTetraFluoroEthylene (PTFE), silicon, nitrile, and fluoroelastomer.

The different types of oil seals makes them a dynamic product, which can be used in a number of different industrial applications such as:

• Electric motors
• Gearboxes
• Paper rolls
• Industrial pumps and fans
• Customized equipment

Benefits of Oil Seals

The strength, flexibility, and durability of oil seals provide a number of benefits to various industrial applications:

• Performance under Extreme Environments:

   

  Oil seals have the capability to work under extreme duress in terms of temperature. This makes them perfect for fluid environment applications. Oil seals work at optimum levels between temperatures of – 70oC and +260oC.

• Low Friction Properties:

   

  Oil seals are designed for low friction applications. The lubrication within the oil ensures that the sealing lip does not touch the shaft and prevents burning of the sealing lip.

• Long Shelf Life:

   

  Sealing materials such as PTFE and fluoroelastomer ensure that the oil seals can be used for long periods of time.

• Easy Assembly: Oil seals can be easily replaced within a few minutes without disassembling the entire machine. Oil seals are also compact in size, making easier to handle and replace when it comes to assembly.

• Reduced Weight: Manufacturers design oil seals to be light in weight, while having the required strength properties to work under stressful environments.

• Good Substitutes for Standard Seals: Specialized oil seals can be used as an alternative for standard lip seals that are used for dry or poorly lubricated conditions.

As one can see, there are many benefits that come with using high performance oil seals for industrial applications.
