Oil seals are the key parts of mechanical equipment used in hydraulic systems, pumps, pistons, pipe connections etc. These are used to prevent the leakage of any lubricant and close the spaces between the moving and stationary components. These products are also known as shaft seals, fluid seals, grease seals, dirt seals, or rotary seals. These seals can stop any harmful contaminants from entering the machine in demanding environments. They also help to prevent the intermixture of two different mediums such as lubricating oil & water.
An oil seal is designed to offer optimum sealing performance. Some of the major functions of oil seals are as below.
Although there are various types of oil seals based on the application’s requirement, they all are made of three primary elements like rubber sealing element, metal case/reinforcement and garter spring. There are many materials used for oil or shaft seals that vary in resilience to the specific condition. These materials have properties that make them perfectly suitable for the required application. Metal cases/reinforcements of the seals are made of carbon steel or stainless steel based on the application which provides strength and rigidity to the seal. The metal surfaces exposed to the environment are treated to protect them from corrosion during normal handling and storage. The purpose of the garter spring which is located on the lip of the oil seal is to support the lip and prevent the leakage of lubricant and other contaminants from entering.
Oil or shaft seals are made from several materials based on the requirement of the application. However, the material selection is one of the important parameters considering several factors like operating temperature, environment, pressure, and maximum shaft surface speed, among others. The most commonly used materials in oil seals are Nitrile, Viton, Silicone, and Teflon which exhibit the below characteristics resulting in better life and performance of the seal.
The oil or grease seals are used in a wide range of applications in automotive, construction, agriculture, oil and gas industries, material handling, mining and so on. They are used in:
The durability and flexibility of oil seals provide many benefits to different industrial applications:
Before you install a fluid seal, you must consider the type of application parameters within which it must function. This is important to ensure that you have installed the right seal. So while choosing the right fluid seal for your purpose, you should consider the below important factors. The designers and engineers of Sujan Industries ensure the below main factors before developing any type of oil or fluid seals:
Keeping in mind these important factors will also determine the proper materials for building your oil seals. However, mistakes in the selection can result in total failure, premature wear, excessive internal pressure on the seal, cracks, lip hardening, swelling, etc.
And over time, this damage can lead to massive expenditure, specifically, if you overlook these issues and don’t address them promptly. However, selecting a proper profile for the application ensures optimum performance and a safe working environment for the upcoming years.
