Wheel oil seal
85*121*12/19
Good surface gloss, good elasticity, excellent sealing effect, good weather resistance, good material stability, customized non-standard models, mature technology, stable quality
(1) Shaft speed Due to design and structural reasons, high-speed oil seals should be used for high-speed shafts, and low-speed oil seals should be used for low-speed shafts. Low-speed oil seals cannot be used on high-speed shafts, and vice versa.
(2) The degree of eccentricity on the installation If the eccentricity of the oil seal and the shaft is too large, the sealing performance will be deteriorated, especially when the shaft speed is high. If the eccentricity is too large, a "W"-shaped oil seal can be used.
(3) Note that there should be a certain amount of lubricating oil on the lip of the oil seal.
(4) Special attention should be paid to prevent dust from immersing in the oil seal.
(5) The oil seal with general pressure has poor pressure bearing capacity, and the oil seal will be deformed when the pressure is too large. Under the condition of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used.
(6) When the ambient temperature is high, polyacrylate or silicon, fluorine, and silicon fluorine rubber should be used. And should try to lower the oil temperature in the tank. When the operating temperature is too low, cold-resistant rubber should be used.
(7) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.

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 |
