Truck rear hub inner oil seal 8-94336-316-1 metal shell oil seal Size: 80*113*12/20
It is a typical representative of oil seals. Generally speaking, oil seals refer to skeleton oil seals. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the external environment, so as not to let the lubricating oil leak. The skeleton is like the steel bar in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. According to the structure, it can be divided into single-lip skeleton oil seal and double-lip skeleton oil seal. The auxiliary lip of the double-lip frame oil seal acts as a dust-proof function to prevent external dust and impurities from entering the machine. According to the frame type, it can be divided into inner frame oil seal and exposed frame oil seal
A robust hub seal with a multi-point exclusive labyrinth built into a single housing, this seal is the ultimate seal to keep elements out and oil out while minimizing friction. Unique design provides excellent contaminant removal at optimized surface velocity. -
320/03119 – JCB excavator oil seal, engine oil seal, crankshaft oil seal
The role of the engine oil seal is to keep the various components of the engine operating in the lubricating oil environment, to prevent lubricating oil, lubricating oil or other oil leakage or leakage, etc., and to prevent dust from infiltrating, and to maintain good lubrication conditions for rolling or sliding friction parts ,Extended service life.

Rear crankshaft oil seal RE44574 engine oil seal size 145*117*13
This is a relatively special structural form, which is different from ordinary oil seals, and generally consists of two parts: an outer ring and an inner ring. The outer ring is a bit like our ordinary skeleton oil seal, but it is usually specially designed, such as positioning, dustproof, oil storage and other structures. Its special place is the internal slip ring. When working, the slip ring rotates with the rotating shaft, and the sealing lip only cooperates and rubs with the slip ring.

Truck hub oil seal 80*120*17/12 Support OEM customized size
Oil seals are commonly referred to as grease, fluid, dirt, or lip seals. Oil seals are an integral part of any rotating and moving part assembly.
They close the space between fixed and moving parts in machinery. In most applications, seals are either partially or temporarily immersed or only exposed to splashed lubricant, especially in engines, transmissions, gearboxes or axles. They are an essential part of nearly every machine and vehicle in operation. Oil seals generally consist of three basic components: the sealing element (the nitrile part), the metal housing, and the spring. It is a widely used sealing element. The role of the seal is to prevent the medium from leaking along the moving parts. -
Truck hub oil seal 58*102*10/28 metal bracket, support customized size
Hub oil seal: hub oil seal is a daily car maintenance. The number of times the car oil seal may be replaced belongs to the auto parts with a large amount. The oil seal can also be called the oil retaining ring. Many of the car parts are installed with oil seals. For example, the parts of rolling bearings or sliding bearings on the car are used to prevent lubricating oil or other oil leakage or leakage, etc., and can also prevent dust from infiltrating, maintain good lubrication conditions for rolling or sliding friction parts, and prolong the service life. life.

9Y9895 front crankshaft oil seal, support logo, OEM size customization
Crankshaft oil seal sealing principle: Since there is an oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has fluid lubrication characteristics. Under the effect of the surface tension of the liquid, the rigidity of the oil film just makes the oil film and the air contact end form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft.

Sinotruk engine oil seal VG1246010005/2 crankshaft front oil seal, felt oil seal, support customized size
Wool felt oil seals are used to prevent the leakage of lubricating oil at friction points or transmission parts, and prevent moisture and dust from falling into friction points, and act as seals and oil protectors for various shafts, wheels, and bearing transmission parts. A thin, adherent oil film exists between the seal lip and the shaft contact surface. The existence of this layer of oil film, on the one hand, can play the role of sealing the fluid medium, on the other hand, it can also serve as a wool felt oil seal between the lip and the shaft, which is used to prevent the leakage of lubricating oil at friction points or transmission parts, and prevent moisture. And dust falls into the friction place, and acts as a seal and oil protector for various shaft wheels and bearing transmission accessories. “

Rubber tc oil seal TC35x50x8 factory production support custom size, sample service
The TC oil seal isolates the part that needs to be lubricated from the output part in the transmission part, so that the lubricating oil will not leak. Static seals and dynamic seals (usually reciprocating) seals are called oil seals. The representative form of oil seal is TC oil seal, which is a fully covered rubber double-lip oil seal with self-tightening spring. Generally speaking, the oil seal often refers to this TC skeleton oil seal. The TC profile is a shaft seal consisting of a rubber-coated metal cage, a main sealing lip with integrated spring and an additional anti-contamination sealing lip.

50/5076 valve stem seal, support OEM customized size, sample service
The valve oil seal is a kind of oil seal, which is generally vulcanized by the outer skeleton and fluorine rubber. The diameter of the oil seal is equipped with a self-tightening spring or steel wire, which is used for sealing the engine valve guide rod. The valve oil seal can prevent engine oil from entering the intake and exhaust pipes, causing oil loss, preventing the mixture of gasoline and air and exhaust gas from leaking, and preventing engine oil from entering the combustion chamber. The valve oil seal is one of the important parts of the engine valve group. It is in contact with gasoline and engine oil at high temperature, so it needs to be made of materials with excellent heat resistance and oil resistance, generally made of fluorine rubber.
