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.

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.
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.

In any mechanical manufacturing company, optimal performance and long service life are vital to your products&#; success in the market. No matter how much we go deeper in considering the brand and in deciding which one would last longer than the other, it&#;s also significant to at least put into consideration the importance of maintenance and preventive measures.
If there is any component that is underappreciated within a mechanical assembly or a bearing assembly, it would be the oil seal. Due to its relatively inexpensive cost, the importance of oil seals is often being overlooked and neglected. However, being a game changer in a bearing assembly, one must know the benefits it contributes in keeping your machine in perfect shape.
Often called a rotary shaft seal, oil seals purposely serve to close the gap between stationary and moving components. When properly installed, oil seal&#;s main job is to retain or separate fluids. Furthermore, it also helps in preventing lubricants from escaping the gauge as well as it prevents foreign contaminants from moving in through the clearance. Seals also serve to prevent intermixture of two fluid mediums such as oil and grease . An oil seal that fails and create seal leakage, enables abrasives and corrosive moisture apart from allowing sediments to enter your machine.
Bearing manufacturers stress the importance of selecting the right seal for your machine for each has its own distinct differences. The selection of the right seal is crucial for the maintenance and integrity of a given application due to some situations wherein not all are fit to work on some machines.
Failure to follow common application best practices potentially results in costly mistakes or worse, system or machine failure.
What are the benefits of Oil Seals ? Is it cost-effective?
Aside from keeping your machines in its best shape, oil seal has so much to offer than what&#;s mentioned above. Some of these are as follows:
Oil seals work like glue between two elements: a stationary and moving component. Their function is to remove the spaces between such elements to ensure both components resist non-lubricity. This is especially important in a precision bearing. Any non-lubricated contact from both the seal and other elements can lead to a catastrophic failure. This will result to seal damage and ultimately, extended maintenance downtime.
Oil Seals also serve as a prevention method ensuring that no foreign objects such as dirt and soil enter your equipment. Since seals are employed in a variety of applications (from industrial to automotive), an effective seal must maintain a high-impenetrable degree of exclusion when it comes to contaminants or foreign objects that would aggravate the performance of your machineries.
However, in some cases when you have been caught up in a situation such as seal failure while it&#;s under the process of filtering out contaminants, possible event such as excessive mechanical strain may be introduced resulting in mechanical failure.
In addition to the list of positive things it does to our mechanical applications are:
Applications of oil seals
Oil seals play a major role in mechanical assemblies. Their strength and flexibility allows them to be used in numerous industries (any automotive or industrial application that has a rotating and moving part assembly) such as gearboxes, electric motors, industrial pumps, fans, and customized equipment.
In particular, oil seals are utilized in mechanical environments that must function under extreme pressure. This concept often applies to temperatures in which oil seals must operate. With its high degree of flexibility and use in various industries, oil seals must be able to work optimally in temperate conditions of &#; 70°C and +260°C.
Oil seals must also work in extreme fluid environments in which the risk of foreign contaminant is great. While most oil seals appear in the traditional &#;o-ring&#; shape, oil seals can be manufactured to the specifications of each application. This means there&#;s a sealing solution for any uniquely designed equipment.
According to your requirements, the types of oil seals you can select from include:
Choosing the right oil seal
Before an oil seal is installed, considerations must be made with regard to the type of application parameters that it must function within. Considering these variables and factors ensures the right one is installed. A sound replacement affords mechanical longevity and proper functionality.
When selecting the right oil seal for your application, nine factors must be taken into consideration. Top bearing companies, designers, and maintenance engineers have specified the nine factors as:
These nine factors will also determine the right materials that your oil seals should be made of as wrongful selection can result in failure, including excessive internal pressure on the seal itself, premature wear, lip hardening, cracks, and swelling.
Over time, this damage can incur massive costs.-particularly if such issues are not promptly addressed.
While there are a variety of oil seals to select from, it&#;s important to choose the right profile for the application. This not only guarantees optimum performance for the applications but it also ensures a safe working environment for years to come.
