Truck rear hub oil seal 125*160*17

Short Description:

The 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 of consumption. The oil seal can also be called the oil baffle. Among many auto parts, many are installed with oil seals, such as on the car. The function of the rolling bearing or sliding bearing and other parts is to prevent the leakage or leakage of lubricating oil or other oil. Engine: Crankshaft – crankshaft front and rear oil seals, valves – valve oil seals, transmission – transmission front and rear oil seals, transfer case – transfer case front and rear oil seals and other parts of the car need oil seals.

Rubber oil seal


The main factors that cause oil seal oil leakage:

The oil seal is not tightly sealed is the main factor causing oil leakage. When the shaft is worn and a groove is formed, even if the oil seal is replaced with a new oil seal, it still cannot be sealed, because the contact pressure between the oil seal lip and the shaft decreases, resulting in too little interference between the diameter of the oil seal lip and the shaft diameter after installation.
Taking the oil seal of the crankshaft of the S195 diesel engine as an example, the main reasons for the lack of strict sealing are as follows:
①The manufacturing quality of the oil seal is poor;
②The quality of the shaft or bearing is poor;
③ Improper use and maintenance;
④ Improper installation;
⑤ Improper storage, adverse effects caused by environmental pollution

Countermeasures for oil leakage due to poor sealing of oil seals:

1. Master and identify the basic knowledge of fake and inferior products, and choose high-quality and standard oil seals.
2. During installation, if the outer surface roughness of the shaft diameter is low or there are defects such as rust spots, rust, 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 crush 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.
3. Oil seals used in machinery are generally subject to harsh working conditions, large environmental temperature differences, a lot of dust, and frequent machine vibrations, which make the mechanical parts constantly changing, and should be inspected, maintained and maintained frequently.

material Low
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
