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:

 

  • Prevent the entry of foreign contaminants
  • Prevent seal leakage
  • Maintain a bearing’s lubricity

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:

  • Ability to perform in extreme environments
  • Long shelf life
  • Easy assembly
  • Low friction properties
  • Increased strength properties to work in stressful environments

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:

  • Single and double lip oil seals
  • Metal cased, external, and internal orientated oil seals
  • Spring-energized oil seals.

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:

  • Shaft speed
  • Temperature
  • Pressure
  • Shaft hardness
  • Shaft surface finish
  • Concentricity
  • Shaft and bore tolerances
  • Runout
  • Lubricant

 

 

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.

Oil seals are vital to the daily operation of most factories and a wide range of industrial and commercial equipment. They are available in imperial and metric dimensions for both single- and double-lip design. Motors, Mechanical Hydraulic systems, pistons, and pumps utilize oil seals to protect internal components. Depending on the application, there are various material, size, and configuration options to best fit your needs.

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.
