Oil Seals

In terms of an oil seal, there are a lot of different types. Depending on how they are constructed, U-ring oil seals as well as block vee rings can be used as a rod seal, a piston seal or even a symmetric seal. U-rings and block vee rings are called single acting seals, also known as unidirectional seals, and have to be mounted back to back in cylinder applications that are double acting. A Block Vee seal is really more compact and performs better under high pressure conditions than a U ring does. V ring seals are made of all rubber and are primarily used to get rid of dirt and other types of contaminants. V rings are stretched over a shaft and sealed against the side of housing or another type of machine component. Besides, more oil seals are introduced as there are several different kinds of clearance seals, also known as labyrinth seals. The one feature they all share with each other is that they all work on a principle of positive clearance. This means that there isn’t any rubbing that occurs against the shaft or the housing.


A lot of labyrinth seals are made up of a rotor, which rotates, and a stator, which is static, piece with a radial gap between the two pieces. The gap has to be bigger than the radial clearance of the bearing that is being sealed. Also, the operating speeds as well as the temperature have to be considered when utilizing a labyrinth seal. These kinds of seals typically don’t perform very well at lower operating speeds. Another type of labyrinth seal is a laminar sealing ring, which utilizes a series of flat metal rings, similar to washers, of different diameters to make a labyrinth seal. Bearing isolators are a dynamic kind of seal that is designed to keep bearings protected from outside elements. They are also made up of a rotor, a rotating piece, and a stator, or static member. Some bearing isolators are made out of labyrinth construction but others use O rings or other kinds of positive seals.

What Are the Uses of Oil Seals?

Oil seals are also known as dirt, fluid, or grease seals. The main function of this tool is to close the spaces between the moving and stationary components of any mechanical equipment. Seals help in preventing the escape of lubricants.


This tool stops any harmful contaminants to enter the machinery particularly in extreme environments. This tool plays a vital role for a successful vehicle operation and proper functioning of every kind of machine. It help protects all kinds of precision-constructed, roller, sleeve, and close-fitting ball bearings.


For precision bearings, seals help in preventing lubricants from running away from the bearings or spilling off in a specific area. For machine components, this tool helps in preventing the occurrence of corrosive moisture, abrasives and stops any harmful contaminants to enter the machine. Seals also help in preventing intermixture of two kinds of medium like water and lubricating oil.


Thus, it is very important to choose the right kind of oil seal for your machine. Choosing the best manufacturer or supplier is essential in finding a precise sealing design. It is important to note that grease seal must match to the aftermarket applications or original equipment.


This is to ensure that your machine will have a reliable and consistent performance. Oil and grease seals are used in almost all kinds of machineries and it is used in wide array of applications. Seals are used in power transmission, oil refineries, off-highway, manufacturing, and automotive applications.


In a standard application, dirt seal is usually installed adjacent to the bearing. It is either sealed in or sealed out as required by the machinery depending on the varying kinds of solid, gases, or liquids that come across a particular mechanism. Thus, it is important to note that before selecting the lip material or sealing element, you should determine first the operating environment of the oil seal.


By doing so, you can be assured that you can have the right type of seal for the specific function and or mechanism. Fluid seals are also made from various compounds and materials. It can either be made from PTFE, tetrafluoro-ethylene propylene, fluoro-elastomer, silicone, polyacrylic or ethylene-acrylic, polyacrylate, nitrile, urethane, leather, and felt compounds.


Industrial type of seals is also available in varying sizes such as some are small-bore from zero to 13 inches. There are also high-temperature and metric varieties of grease seals. Thus, it is important to have a precise sealing design that is matched with the original equipment so you can have a consistent, accurate and reliable operation.
