115*140*​​16 truck hub oil seal, NBR rubber rear crankshaft oil seal, metal shell oil seal

Short Description:

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.

Sealing ability of oil seal

It depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak; At the same time, it is necessary to apply some oil on the sealing ring, and at the same time, ensure that the skeleton oil seal is perpendicular to the axis line. If it is not vertical, the sealing lip of the oil seal will drain the lubricating oil from the shaft, and it will also cause excessive wear of the sealing lip. During operation, the lubricant in the casing seeps out a little to achieve the ideal state of forming an oil film on the sealing surface.

Oil seal features and performance:

1. Good wear resistance, high tear resistance and good bending strength;
2. Tensile strength and elongation at break;
3. High temperature resistance, hardness;
4. Low compression rate;
5. Good oil resistance, corrosion resistance, solvent resistance, high mechanical strength and long service life;
6. Good resistance to ozone and aging;
7. Non-toxic and environmentally friendly.

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
