What things do you consider when selecting oil seals?
Oil seals are essential components used in various machinery and equipment to prevent contaminants, dust, water, and other hazardous materials from entering the system. There are many different types of oil seals available on the market today that can suit various applications and specifications.
When selecting an oil seal for your needs, consider material type, shape, thermal expansion resistance capabilities, sealing qualities, spring-loaded lip design for airtightness around shafts, durability against wear and tear or abrasive materials, and more.
Before selecting an oil seal, let’s have a detailed look at each factor.
Material Type
Oil seals come in several materials, including rubber, metal, and leather, each different offering properties for specific applications.
Rubber: Rubber is highly flexible and can easily be press-fitted in housings with enough interference on that same rubber material – guaranteeing static sealing all around!
Metal: Metal-cased oil seals are the most reliable type when it comes to providing optimum protection against contaminants, dust, and water – making them an ideal choice for extreme environments.
Leather: Leather oil seals are the way to go for applications requiring an exceptionally tight seal, ensuring a secure fit and preventing any leakage or contamination from occurring.
Size Selection
The size of the oil seal must match the dimensions of the shaft or housing accurately. Wrongly sized seals can lead to inadequate sealing and might not fit properly in place. Hence, checking for the right diameter and width before purchasing an oil seal for your application is crucial.
Oil seals are available in a wide array of sizes, from tiny fractions of an inch to much bigger diameters. For instance, standard metric oil seals range from as small as 4.5mm in diameter and 3 mm in width all the way up to 200mm in diameter and 50 mm in width. Imperial sizes also exist, ranging from 3/16” in diameter and 1/8” in width up to 13.25” in diameter and 2” in width.
Resistance to temperature and pressure
Selecting an oil seal material with adequate thermal expansion resistance is essential. This will ensure its performance and lifespan, especially in applications where temperature variations occur.
Temperature: Different materials react differently to changes in temperature. Some materials may expand or contract more than others, leading to a possible failure of the seal performance if the right material is not chosen. To ensure optimal performance, the seal elastomer must be installed in a mechanism where temperatures remain within its temperature range.
Pressure: The pressure at which oil seals must be able to resist depends on their application. To ensure optimal protection, selecting an oil seal that can withstand pressures that exceed the maximum pressure in the system is recommended. Traditional oil seals are intended for light applications where the internal pressure is up to 8 psi or lower. If your application is subject to greater pressure, a pressure relief system must be implemented.
Hardness/Tolerance
The hardness of the elastomeric material of oil seals must also be taken into consideration. An oil seal with a higher Shore A rating indicates it can withstand more pressure and abrasion, making it suitable for applications involving high friction levels.
Additionally, one should also factor in tolerances when selecting an oil seal. By understanding the tolerance ranges, seal manufacturers can provide an oil seal that is as close to the desired specifications.
Spring-Loaded Lip Design
Oil seals are designed with a spring-loaded lip that provides an airtight fit around shafts. The height of this lip will depend on the size and type of application, but generally, it should be at least half the depth of the shaft. Spring-loaded lips provide a more secure fit than non-spring-loaded designs, providing better protection against contaminants and water.
Shaft speed
Before investing in an oil seal, it is critical to consider the maximum permissible shaft speed, runout, material of the oil seal employed, type of liquid being sealed off and concentricity between the housing bore and shaft. This will help ensure that your oil seal does not suffer from spiraling or abrasions.
Shaft surface finish
To determine the effectiveness of your seal, examine the shaft surface finish. The spiral lead and direction of finishing tool mark significantly impact sealing performance. If they are in excellent condition, then you can be sure that your seals are working optimally!
To attain the best sealing results on your shafts, grinding or polishing them with concentric (not spiral lead) marks is essential. However, if it’s unavoidable that there are Spiral finish leads present, they should be rotating toward the liquid when the shaft spins.
Lubricant
The proper oil or lubricant is essential for the effective performance of any oil seal. To ensure that your seal’s life is extended, select a lubricant that corresponds with the elastomer material used in its lip and has a fitting viscosity for the application at hand.
Otherwise, an incompatible selection can lead to premature wear and tear of the seal itself!
The above should be an excellent starting point to help determine which oil seal is best suited for your application. It is always advisable to consult with an expert to discuss further the specifics of your application and get the best advice on choosing an oil seal.
When selecting the right oil seal, it is important to consider other factors such as behavior, design, working environment, operating conditions and cost.
