crankshaft oil seal
120*140*12/13
Engine: Crankshaft--Crankshaft front and rear oil seal valve--valve oil seal (engine repair kit o-ring) (distributor oil seal, water pump oil seal, balance shaft oil seal, oil pump oil seal...); Camshaft--Camshaft oil seal ; Transmission: Transmission--transmission front and rear oil seals, shift lever oil seal (transmission repair kit o-ring) (transfer case--transfer case front and rear oil seals); Rear axle: half shaft--rear half shaft oil seal difference Gearbox -- (front) rear angle vector oil seal, rear wheel oil seal, front wheel oil seal, direction oil seal (steering machine repair kit o-ring), steering booster oil seal (front axle oil seal).
All parts that have liquid lubricating oil in the running body box and are connected to the outside need oil seals. Some are rubber, some are metal, most are steel rubber, such as crankshaft rear oil seal, gearbox front and rear oil seals, left and right half shaft oil seals, main reducer front oil seals, air compressor crankshaft oil seals, etc.
When installing, if the outer surface roughness of the shaft diameter is low or there are defects such as rust spots, corrosion, burrs, etc., use a fine emery cloth or oil stone to smooth it; apply clean oil or grease on the oil seal lip or the corresponding position of the shaft diameter. Apply sealant to the outer ring of the oil seal, wrap the keyway on the shaft with hard paper to avoid scratching the lip of the oil seal, and use a special tool to rotate the oil seal inward and press it in. Do not smash hard to prevent the oil seal from being deformed. Or squeeze the spring and fail; if the lip is flanged, the spring falls off and the oil seal is skewed, it must be removed and re-installed. It should be noted that when the shaft diameter is not worn and the oil seal spring has sufficient elasticity, do not tighten the inner spring without authorization

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 |
