Truck shaft hub oil seal 95*130*12/20 skeleton oil seal, support sample customization

Short Description:

The skeleton oil seal structure consists of three parts: oil seal body, reinforced skeleton and self-tightening coil spring. The sealing body is divided into bottom, waist, cutting edge and sealing lip according to different parts. Usually, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain “interference”.
Therefore, when the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal cutting edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will decrease rapidly or even disappear. , Therefore, adding a spring can compensate the self-tightening force of the oil seal at any time.

The role of skeleton oil seal:

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.

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
