Basic information of oil seal:
Wheel 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. Parts such as rolling bearings or sliding bearings 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 service life.
Advantages of oil seals:
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.

| material | Low TEMP. |
High TEMP. |
Performance | ||||
| NBR | -40 | 120 | Good resistance to alcohol,amines, petroleum oils, and gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters |
||||
| HNBR | -25 | 140 | HNBR is made from NBR by hydrogenation. It has high temperature resistance, abrasion resistance and good physical properties. |
||||
| ACM | -25 | 150 | It is used in diaphragm, hose for automotive application. Good resistance to heat, ozone and oil. Generally attacked by water, alcohol, glycol and aromatic hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance. |
||||
| EPDM | -40 | 125 | Stable in polar fluids (alcohol, ketone, and glycol), and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler. |
||||
| VMQ | -60 | 125 | The most widely temperature ranges for application. Good weather and ozone resistance, but poor mechanical property and chemical resistance. |
||||
| FKM | -20 | 250 | Fluoroelastomers have a high degree of chemical stability and are currently the best media resistance of any elastomer. Type 26 fluoroelastomer resistant to petroleum-based oils, diester oils, silicone ether oils, silicic acid oils, inorganic acids, most organic, inorganic solvents, drugs and so on |
