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.

Ways to Measure and Choose Oil Seals for Industrial Applications

Oil seals are used in several industrial applications to protect shafts and bearings from oil, grease, contamination, and dirt. They comprise an outer and an inner circular rings. The outer ring or disk is made of metal, while the inner one is made of rubber and hence is flexible. It is stuck onto the outer ring with the help of a chemical adhesive. There are oil seals with single lip as well double lips. The sizes of these seals depend on application requirement, and hence it is measure the inner and outer diameters, width, and so on. Also, it is crucial to choose the right type of oil seal for every application. This post discusses the way to measure and choose the oil seal for your application.

How to Choose the Right Oil Seal Type?

You may have to choose or identify the oil seal type in case of either a new equipment fitment or as a replacement for the damaged one. Here are a few pointers to identify the right seal type.

• Primarily, there are single lip and double lip oil seals. The single lip is the immersed at the bottom for which the inner diameter needs to be considered.
• Double lip oil seals have an extra lip at the top which protects from external contamination, dirt, and so on.
• Pressing along the line of the inner diameter at the top may help determine whether the oil seal is single lip or double lip.
• Check the code of the lip seal given by the manufacturer or look for a reference guide for further information regarding the oil seal type. This is because there are several types of single lip as well as double lip seals with varied configurations such as type A, B, or C single lip and type BO, ADL, double lip, and so on.
• Type B seals have their outer diameter made of metal, while in case of type A it is made of rubber. In type C, there is reinforced metal added for structural stability. Likewise, there are several types of materials and their permutations and combinations.
• All of these oil seals based on their materials have specific physical and chemical properties, and accordingly find applications in diverse industries. For instance, type C single lip offers structural stability and hence finds use in heavy engineering. Type A made of rubber has amazing resistance to heat, chemicals, and so on. Hence, they find application in industries where there is exposure to chemicals, abrasion, and elevated temperatures.
• Before you choose the type of oil seal, it is essential to measure it, which is discussed in the next section.

How to Measure Oil Seals?

Oil seals are typically used as seals in moving parts that prevent friction as well as mixing of liquids or other elements. The oil seeps between the lip and shaft and that lifts up the lip. This creates the required gap between the lip and shaft as they should never come in contact with each other. This is basic working mechanism of oil seals. When replacing these oil seals, it is essential to measure them since they have different dimensions based on the application they are fitted in. Here are some pointers regarding their measurement.

• While visual inspection may offer some clue, it may not be accurate. Hence, measuring the inner and outer diameter with the help of calipers is important.
• Their measurement is much like O-rings, wherein, height, lip, type, inner and outer diameter are important factors. Material is also a factor to be considered although it cannot be measured.
• Take at least three readings, preferably with a Vernier caliper. Consider the average reading if there is negligible difference among the values.
• Measure the bearings and also consider the gaps.
