Oil seals are widely used as sealing devices for machines.
JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.
Therefore, this series of columns will summarize the following in order:
• The structure, functions, and types of oil seals
• How to select the right oil seal
• Handling of seals, and causes and countermeasures for oil seal failure
Oil seals, also known as rotary shaft seals, are a type of gasket used to prevent lubricant leakage and contamination in rotating machinery by creating a barrier between the moving and stationary parts.
Additionally, the gasket acts as a barrier to prevent the entry of contaminants such as dust, dirt, and moisture into the engine, which can cause damage or corrosion to engine components.The valve cover gasket's primary function is to prevent oil from seeping out of the engine and into areas where it could cause damage or compromise efficiency. A leaky valve cover gasket can lead to oil loss, which in turn can cause engine damage due to insufficient lubrication. Furthermore, oil dripping onto hot engine components can ignite, posing a fire hazard. As technology advanced, so did gasket automation. Precision became a key focus, with computer-controlled cutting devices replacing handcrafted methods. These CNC (Computer Numerical Control) machines could replicate exact measurements and patterns with minimal waste, optimizing material usage and lowering costs.
Global O-Ring and Seal’s oil seal part numbers are designed to describe the seal size, style, and material composition. When searching for oil seals via our online store, you will not only be presented with your selection but with comparable oil seals of the same dimensions. There are often viable style substitutions that are functionally compatible but with additional features. With over 50,000 unique oil seals in our database, you can cross-reference 215,000 part numbers of OEMs and Manufacturers. In the Search Bar above, simply type the OEM/manufacturer part number alone (no need to type the name), and the oil seals matching that part number will be displayed.
Viton Oil Seals - A synthetic rubber and fluoropolymer elastomer, Viton is used to make oil seals that provide resistance in both high temperature, up to 250°C and low compression set components. They also offer a high resistance to chemicals and abrasions, so they can be used in elements that regularly interact with petroleum and solvents.
Car oil seals, a seemingly insignificant component in the grand scheme of a vehicle's mechanics, play an indispensable role in ensuring the longevity and efficient operation of your car's engine. These seals, typically made from rubber or synthetic materials, act as barriers between moving parts, preventing oil leaks and maintaining optimal lubrication. TC oil seals, also known as 'Teflon' or 'PTFE' seals, are named after their primary material, Teflon, a synthetic fluoropolymer with exceptional chemical resistance and low friction properties. The 'C' in TC stands for the metal casing that reinforces the seal, providing added strength and durability. These seals are commonly used in high-pressure and high-temperature environments where standard rubber seals may fail. Installation and maintenance of high pressure oil seals require precision and expertise. Incorrect installation can lead to premature failure, while regular inspection and timely replacement are necessary to ensure continued performance and prevent unexpected downtime.When it comes to maintaining the performance of your vehicle, one of the most important components to consider is the spark plug. The spark plug plays a crucial role in igniting the air-fuel mixture in your engine's combustion chamber, which in turn powers your vehicle. Among the various brands and types of spark plugs available in the market, Mico spark plugs are known for their quality and reliability.
Oil lip seals play a significant role in several industrial applications to avoid intermixing fluids and prevent contaminants and moisture from affecting the bearings. With such a vital role to play, it is essential to choose the right material for these seals. The choice of the material will depend on factors like the type of fluid being sealed, operating temperature, pressure, and compatibility with the operating environment. The following list of materials is typical for making oil lip seals:
Common materials used in oil seals include nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material of the oil seal, the compatibility of the material with the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft at high speed must be considered. When the oil seal is working, the temperature of its lip is higher than the working medium temperature by 20~50°C. Attention should be paid when selecting the oil seal material. The working range of the oil seal is related to the material used for the oil seal: the material is nitrile rubber (-40~120°C), Aggreko rubber (ACM) -30~180°C, fluorine rubber (FPM) -25~300°C.
Rectangular rubber gaskets can be made from a variety of materials, each with its own unique properties. The most common materials used for these gaskets include neoprene, nitrile, silicone, EPDM, and fluorocarbon rubber. The primary function of a TC oil seal is to create a barrier between two moving parts, typically a rotating shaft and a stationary housing. By doing so, it prevents the loss of hydraulic fluid or lubricant, which is crucial for the proper functioning of the machine. At the same time, it also prevents external contaminants from entering the system, thus maintaining its cleanliness and extending its service life. The primary function of the engine oil seal is to create a tight seal between the engine block and the rotating shaft, such as the camshaft or crankshaft. By doing so, it prevents oil from leaking out of the engine and also prevents dirt and debris from entering the engine. This is particularly important because oil is essential for lubricating the engine's moving parts, reducing friction, and dissipating heat. Without an effective oil seal, the engine could overheat, leading to severe damage and costly repairs.
