There are a variety of oil seals used in a variety of applications to help close the space between a stationary and a moving part.  By closing the space it prevents any lubricants from escaping.  Additionally, oil seals help create a seal that prevents any contaminants from entering machinery which can cause a host of problems.  Mechanical equipment and machinery require different size or type oil seals to ensure that there is a superior and precise seal.  Because oil seals help reduce contamination or mixing of materials it prolongs the life of machinery and helps ensure a more reliable performance.

There are a wide variety of industrial applications and therefore there are a wide variety of oil seals to meet the specific application needs.  By choosing the right oil seal you will have a better fit, improved stability, and enhanced reliability.  Rubber tends to be one of the most commonly used oil seal materials. SKF, an oil seal manufacturer, explains how oil seals for and the importance of proper installation, 'To provide effective sealing, radial shaft seals must be installed properly. An experienced installer with suitable tools, working in a clean environment, is recommended to provide proper installation. The shaft counterface surface and housing bore should meet the demands specified in the sections Shaft requirements and Housing bore requirements. To facilitate seal installation and to achieve initial lubrication, prior to installation, SKF recommends wiping the shaft and seal with the lubricant that is going to be retained. While the outside diameter of metal-cased seals can be lightly lubricated to ease installation, the outside diameter of rubber covered seals should always be lubricated.

Seals with an auxiliary, contacting lip can also be filled with grease between the sealing lip and auxiliary lip to reduce frictional moment. This does not apply to silicone rubber seals and seals with hydrodynamic features, other than SKF WAVE lip designs. SKF also recommends using a hydraulic press, with suitable tools, to install a seal in its housing bore. Pressure should be applied as close as possible to the outside diameter of the seal.'  Oil seals are commonly used in a variety of industries. Below are 5 types of oil seals used in today's manufacturing and machinery industry.

Overview of Oil Lip Seals

Oil seals are used to fill gaps between stationary and revolving parts of equipment, often known as radial shaft seals or rotary seals. These seals are frequently employed to keep impurities out and prevent lubricating oils, hydraulic fluids, or other liquids from escaping out of the system. An oil seal features:

• Outside Metal Ring: The seal's outside metal casing helps in maintaining its shape and offers structural support.
• Rubber or Elastomeric Sealing Lip: The sealing lip typically encloses the shaft in a tight seal formed of rubber or elastomeric material.
• Spring: Some oil lip seals incorporate a spring to apply constant pressure against the shaft, ensuring a secure seal.

Types of Materials Used for Manufacturing Oil Seals

Oil lip seals play a significant role in several industrial applications to avoid intermixing fluids and prevent contaminants and moisture from affecting the bearings. With such a vital role to play, it is essential to choose the right material for these seals. The choice of the material will depend on factors like the type of fluid being sealed, operating temperature, pressure, and compatibility with the operating environment. The following list of materials is typical for making oil lip seals:

• Nitrile (NBR): The nitrile rubber or nitrile provides excellent resistance to numerous oils and greases, including mineral grease and hydraulic oil. There are several synthetic lubricants and greases in the market based on glycol which may cause harm to NBR rubber compounds depending on their composition. Due to their excellent durability and cost-effectiveness, these seals are used in a wide range of operating conditions. However, NBR is unable to withstand exposure to acids and solvents.
• Polytetrafluoroethylene (PTFE): This fluoropolymer is known by the brand name Teflon and is known to assure the best chemical resistance and exceptionally little frictional resistance. It is the material of choice for several types of rotating seals used in the chemical, food, and pharmaceutical industries.
• Polyurethane (PU): Polyurethane seals offer excellent abrasion resistance and durability. They are suitable for high-pressure applications and provide good resistance to hydraulic oils. Polyurethane oil seals are often used in hydraulic and pneumatic systems.
• Viton: The exceptional resilience of Viton against chemicals, strong fluids, and high temperatures is well recognized and makes this a great material for creating seals for demanding applications. This material is known to maintain its flexibility, strength, and shape even in the harshest situations. When designers and engineers use oil lip seals for industry made of Viton material, their durability and dependability guarantee reduced downtime, improved performance, and a competitive advantage. It works effectively in applications involving severe chemicals, synthetic oils, and fuels.
• Ethylene Propylene Diene Rubber: This elastomer is used for creating oil lip seals for industry and other sealing elements such as U-cups. The oil lip seals made of this material would exhibit excellent resistance to steam, hot water, washing agents, and polar organic solvents. They are used to seal phosphate ester hydraulic fluids, such as Skydrol. These seals are not recommended for petroleum-based fluids, and can be effectively used with acetone, steam, alkalies, and dilute acids.

Although oil seals have been around for a while, choosing the right one still needs careful planning. If you are sure about the type of seal needed for your application or looking to replace your current seals with custom oil seals that meet your application requirements, then do not hesitate to contact the experts at SSP Seals ' a leading industrial seal manufacturer in the USA.
