Choose the Right Oil Seals for Chemical Industry

If you are on a quest to buy a good rotary shaft seal to prevent your machinery from unwanted leakages but not sure how to choose one, then the following article will help you with all aspects you need to follow to find the right oil seal for your application.

What is an oil seal?

Oil seal or rotary shaft seals are placed between moving and stationary elements of mechanical equipment, it helps in both oil or grease from leakage and prevents any contaminants or moisture from outside entering with the addition of a dust lip. Hence, it is important to close the gaps in mechanical equipment. National oil seals are one of the most used in the chemical industry.

Why leakage happens

The most common causes of lubricant leakage are 

  • Hydraulic machines
  • Gearcases 
  • Improper application
  • Inadequate installation
  • Lack of maintenance practices of sealing systems

National oil seals:

Many companies offer an extensive line of national oil seals that are high quality and reliable solutions for every wheel-end repair. Engineers, with the help of advanced technologies, are committed to providing premium products that exceed the specifications of the original equipment. National oil seals are great for several applications across many fields like automotive, power transmission, manufacturing, textiles, mining, and much more.

  • National oil seals ball bearings
  • Cylindrical bearing
  • Housed units
  • Precision bearings

Are some of the most common and used national oil seals in the industry.

TTO oil seals:

TTO has the longest history in the manufacturing of oil seals for the chemical industry. We can use them in several industries including agriculture, aircraft turbines, industrial pumps & gas. Based on requirements, the oil seal’s components, size, and style may vary. Many TTO oil seals manufacturing companies supply across the globe. They are also used for sealing other fluids like chemicals, food, and water. 

Factors to consider before choosing an oil seal:

  • Temperature- An oil seal is engineered to operate under optimum atmospheric conditions. If the pressure exceeds the designated range, thermal stress can harden since the lip of the seal is forced against the shaft. This results in high radial load, high level of friction, and uncontrollable wear of shaft & seal and if the temperature is too low, the seal may stiffen and leak. In such cases, a switch to another sealing material will aid the extremes.
  • Shaft speed- Select an oil seal that can support without potential failure. The maximum shaft speed depends upon the function of shaft finish, concentration, and housing bore, the material of the soil seal, and the type of fluid being sealed.
  • Fluid media- Understanding the type of fluid the shaft will be in constant contact with is crucial. This will ensure the longevity of the oil seal and key components. 
  • Lubricant amount- Lubricated seals perform the best. However, in some machinery, there can be dry spells. Selecting a leather or PTFE seal will be beneficial in such cases since both can operate with less lubrication than others.   
  • Pressure- Most oil seals can withstand low-pressure applications. Knowing the compressions of your components is important.
  • Material- Elastomer is the primary material, and in addition to that many different materials are used to manufacture oil seals. We should select according to the applications and requirements of your machinery.

From car engines to assembly machines, oil seals are used to remain free from harmful interactions that may cause serious and expensive destruction to any critical parts. By following these steps will help you in finding the best oil seal for your machinery that prevents lubricant leakage and protects the key components from being damaged.
