Skeleton oil seal
95*130*12/20
Generally, it is to isolate the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil leak. It is usually used for rotating shafts and is a kind of rotating shaft lip seal. The skeleton is like the steel bar in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. According to the skeleton type, it can be divided into inner skeleton oil seal, outer skeleton oil seal, and inner and outer skeleton oil seal. The skeleton oil seal is made of high-quality nitrile rubber and steel plate, with stable quality and long service life. Widely used in automobiles, motorcycle crankshafts, camshafts, differentials, shock absorbers, engines, axles, front and rear wheels and other parts.
1. Prevent sediment, dust, water vapor, etc. from intruding into the bearing from the outside;
2. Limit the leakage of lubricating oil in the bearing. The requirements for the oil seal are that the size (inner diameter, outer diameter and thickness) should meet the regulations; it is required to have appropriate elasticity, which can properly clamp the shaft and play a sealing role; it must be heat-resistant, wear-resistant, strong, and resistant to media ( oil or water, etc.), long service life.
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 |
