What is an Oil Seal?
-
A specific type of seal that is an important part of any rotating or moving part assembly.
- Typically, the Oil Seal is installed adjacent to a bearing
- This seals in or seals out, as necessary, the various liquids, gases or solids encountered by the mechanism.
What is the purpose of an Oil Seal?
- An Oil Seal is designed to perform three major functions.
- Prevention of lubricants from leaking outside the seal
- To act as a barrier to retain the lubricating oil
- To prevent dirt and other contaminants from entering the machinery.
How is an Oil Seal constructed?
- Oil seals normally consist of three basic components:
- the sealing element
- the metal case
- the garter spring.
- The sealing element makes up the interior of the Oil Seal and provides structural stability to the Oil Seal.
- The materials commonly used are:
- Nitrile Rubber (NBR)
- Polyacrylate Rubber (PA)
- Silicone Rubber (SI)
- Fluorocarbon Rubber (FKM).
- The metal case is the exterior of the Oil Seal.
- The main function of the metal case is to give rigidity and strength to the seal.
- Often the case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the Oil Seal in the housing bore.
- Common case material types are:
- Carbon Steel
- Stainless Steel.
- The garter spring is located at the end of the primary sealing lip
- Is used to apply pressure to the sealing lip against the shaft as well as prevent the entry of contaminants from the outside.
- Common garter spring material types are:
- Carbon Steel
- Stainless Steel.
NBR Oil Seals
Nitrile - (NBR/BUNA)
- NBR is a synthetic rubber produced from a copolymer of acrylonitrile and butadiene.
- NBR is the recommended seal material for most common applications.
- NBR seals are compatible with water and most common mineral oils and greases.
- They have good abrasion resistance, resistance to compression set, and a high tensile strength.
