What Is an Oil Seal, and What Are Its Elements?

An oil seal has two tasks: Keeping the lubricant in and keeping dirt and contaminants out of rotating components. This separation must be accomplished between surfaces in relative motion, usually a shaft or bearing inner ring and a housing. With correct installation, oil seals can also prevent seal leakage and maintain the lubricity of a bearing to ensure that the rotary shaft and its bearings remain fully functional.

A typical oil seal consists of three common parts: an outer ring, the sealing element, and a spring. The exterior metal ring component provides strength and rigidity to the oil seal in the bore or recessed groove. Attached to that ring is the sealing element. This flexible interior component of the oil seal, the O-ring, prevents any fluid leaks between the shaft and housing. A spring ensures the constant pressure that deforms the O-ring, creating a reliable seal while maintaining radial force on the shaft.

Generally, oil seals vary in materials and types based on the corresponding application. Common materials include:

Nitrile Buna-N 70. NBR is compatible with numerous environmental conditions and is also relatively cost-efficient, which makes it one of the most popular and best-suited materials for the industry. Nitrile works well in the -30° to 250° F range and when exposed to anything from water and hydraulic fluids to gas, silicone, vegetable, or animal oils.

Fluoropolymer. FKMs, or Viton®, are perfect for high-temperature applications up to approximately 400° F. Additionally, they feature low compression characteristics. Seals of this material are highly resistant to solvents, gas, and petroleum or transmission oils, so they are a good fit for applications around these materials.

Silicone. Vinyl-methyl-silicones (VMQs) maintain performance in temperatures from -140° to 392° F. In addition, silicone is resistant to adverse weather conditions, light, and ozone. The healthcare and food industry sectors, as well as pneumatic and hydraulic systems, often use silicone.

Polyacrylate. Polyacrylate is a good combination of quality and cost benefits. It is highly resistant to oxidation and heated oil, withstanding temperatures from -25° F to 300° F. This material has applications in vehicle transmissions, shaft seals, O-rings, and more.

What Benefits Do Oil Seals Provide?

Oil seals can offer: 

Low levels of friction. The lubrication within the seal ensures that the seal lip does not come into contact with the rotary shaft, eliminating the risk of burning or wear.

Compact size and lightweight. Oil seals possess a small and lightweight design, which belies their strong endurance capabilities.

Reliable, rugged performance. Even under harsh conditions or extreme temperatures, these durable components will maintain their seal.

Simple construction. Easy to handle and assemble, oil seals only take a matter of minutes to replace as technicians do not have to take a machine apart.

Versatility. Standard lip seals are best for applications within dry environments, or those lacking lubrication. Oil seals can act as an alternative with increased functionality.

Corteco: The Benefits of using OE Oil Seals over Cheap Replicas

The Benefits of using OE Oil Seals over Cheap Replicas

In the present day we are often conscious of cost and time as both normally work together. We often want something that costs as little as possible and takes the least amount of time to source and fit

In the present day we are often conscious of cost and time as both normally work together. We often want something that costs as little as possible and takes the least amount of time to source and fit. However, going for the cheaper option isn’t always the right thing to do. Often when it comes to vehicle maintenance or repairs buying a cheap part could cost you more in the long run due to additional damage to surrounding components as well as replacing the original part that failed to start with.

As a brand of Freudenberg, the leading manufacturer of oil seals, we believe quality is key and we want to help you choose quality over cost.

Contact us to discuss your requirements of nbr nitrile rubber skeleton oil seal manufacturers china. Our experienced sales team can help you identify the options that best suit your needs.

This doesn’t just apply to cars and end users but also applies to Light Commercial and Commercial Vehicle companies as down time for their vehicles can have a big impact on cost more than anything. More downtime due to repairs means less vehicles on the road completing consignments for customers leading to less revenue.

Below we will run through the benefits of using original equipment over buying cheaper unbranded oil seals from within the automotive aftermarket.

·         Originally installed by vehicle manufactures – Corteco oil seals are selected by vehicle manufacturers and are installed into new vehicle while in production, demonstrating the accreditation in which the brand holds. If OE seals are good enough for vehicle manufacturers then why wouldn’t you replace like for like to ensure that it is maintained to the highest possible standard?

·         Better quality – As the aftermarket division for the largest seal manufacturer in the world, all products are made from high quality material that undergoes rigorous testing to ensure the parts meet the requirements set by the vehicle manufacturer.

·         Less likely to fail, due to the materials and testing mentioned above, this allows you and your customers to have confidence in repairs carried out on the vehicle.

·         Come with warranty – unlike many cheap replicas all quality and original equipment parts will come with a warranty allowing you and your customer reassurance that the part will not fail and if the part does fail prematurely then you can get this easily sorted by contacting the supplier and resolving this in a timely manner.

As these are only some of the benefits of using quality products over cheap replicas we believe it is right to share the negatives to buying a cheaper product.

·         Cheaper material, as replicas are trying to keep the cost of their parts down this often is done by using materials that are of a lower quality making them less expensive to produce and to sell on however, cheaper material means a lower quality part being pushed into the market.

·         No warranty – Unlike with quality parts, replicas often do not come with warranties, this allows them to reduce cost and to sell more parts in the market as failures will often be replaced by the same part causing a repetitive cycle.

·         Less miles before another replacement is needed, due to cheaper material being used. As the parts are cheaper the material will be weaker, meaning the pressure it can withstand will be less, causing it to fail more quickly. A part failing early can have an impact on surrounding components causing them to absorb leaks or take on additional stress this can result in bigger repairs being needed costing your both more time and more money.

·         Prone to premature failures this links back to all of the above points, premature failures occur due to cheap material wearing out or leaking quicker than OE parts.

Although the OE parts cost more initially you will save money in the long run due to the reliability and the parts being able to perform as expected in comparison to the cheaper parts. Just remember buy cheap then be prepared to buy twice.

Oil seals are an essential part of any machinery, from cars and motorbikes to industrial engines and powerplants. Not only do they keep dirt out, but they also prevent fluids from leaking out into the environment. High-quality oil seals play a vital role in extending the life cycle of your machinery by reducing wear and tear on components as well as preventing costly repairs or replacements. Read on to learn more about why it’s so important to invest in high-quality oil seals for all types of equipment.

An Overview of Oil Seals and Their Function

Oil seals are rotary shaft seals that play an incredibly important role in preventing oil leakage from rotary components. These seals are typically made from rubber, metal, polymeric or a combination of all three materials to create a strong seal that is resistant to extreme wear and temperature variance. Oil seals are used to lubricate inner rotors or cylinders of moving parts, allowing them to spin faster and more efficiently. While these rotary shaft seals provide friction so that the rotors stay in place, they also work to prevent external contaminants from getting into the moving parts and ruining the machine's operation altogether. In conclusion, oil seals remain one of the most important components for rotary machinery and their effectiveness should not be overlooked.

Common Materials Used in Oil Seals 

Oil seals are essential parts of engine components to prevent leaks and maintain engine efficiency. Common engine oil seals generally consist of a variety of materials, including neoprene, nitrile rubber, PTFE, silicone rubber and Viton®. Neoprene is resistant to ozone breakdown and common engine oils as well as other chemicals, making it one of the most highly sought-after materials for engine oil seals. Nitrile rubber provides excellent resistance against engine fuel and mineral oils but not gasoline-derived products. PTFE is used because it has low coefficient of friction and excellent corrosion protection characteristics while providing optimal mechanical strength in engine gaskets that require high levels of stiffness. Silicone rubber tends to be more expensive than other materials but has superior heat resistance and can handle higher temperatures that are typical in engines undergoing multiple long-distance trips. Finally, Viton® provides outstanding permeation resistance compared to other commonly used engine seal materials and is compatible with a variety of fluids including hydraulic brake fluids and gasoline fuels. By choosing the right engine oil seal material for the application, engineers can ensure maximum efficiency and performance for engines.

Benefits of High-Quality Oil Seals 

Oil seals are a critical component of any oil-powered system, and having access to a reliable oil seal kit can make all the difference. High-quality oil seals help to maintain oil cleanliness by keeping oil away from adjacent components that may be sensitive to oil contamination. Furthermore, they help form a barrier between two parts that may move relative to each other, helping reduce wear on both components. Through their sealing properties, high-quality oil seals also ensure fluids are contained within the system and don't spill out or lead to other problems. Ultimately, investing in a high-quality oil seal kit can offer lasting protection for your system and reduce costs associated with having to replace or repair your equipment due to oil leaks or contamination.

As is evident, oil seals are an important factor in keeping lubricants and contaminants out of equipment. The material used for the seal can greatly influence its effectiveness. High-quality oil seals made from nitrile rubber are preferred because of their durability and long-lasting performance. This material offers superior resistance to oil, heat, and moisture while also providing flexibility. Sealing systems with proper lubricant maintainance will keep your machinery running efficiently and extend its overall lifetime. The benefits of high quality oil seals far outweigh the initial cost associated with them; they provide a valuable investment as they will keep your equipment functioning at optimal levels throughout its entire life cycle.  In short, it pays to use good quality oil seals. So if you're looking for a way to get the most out of your machines and make sure they last as long as possible, invest in adequate lubrication system maintenance with high-quality oil seals.

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.
