Differential shaft oil seal for Mercedes Benz truck parts NBR rubber seal 85*155*12/33

Short Description:

Oil seals, also known as oil retaining rings, should be installed in all parts of the automobile where rolling bearings or sliding bearings are installed to prevent the leakage or leakage of lubricating oil or grease, and at the same time prevent the immersion of dust or sludge. Good lubrication conditions for rolling or sliding friction parts for extended service life

Differential oil seal

85*155*12/33

Differential oil seal

The differential oil seal is the half shaft oil seal: generally located in the lower part of the chassis of the car, the half shaft oil seal is used to seal and divide the two parts of the drive axle and the wheel reducer.

The role of differential oil seal

1. The outer diameter of the seal is designed to provide better static sealing, limited rebound effect, accurate positioning and a solid foundation for sealing in its housing, and better heat dissipation for low or high viscosity fluids.

2. Depending on the application, apply a compatible lubricant to different areas inside the seal, which will allow for better heat dissipation, lubricate the additional sealing lip during friction and prevent the entry of external contaminants.

3. The rubber bumper positions the sleeve correctly with the main sealing lip. They also use a variety of additional barriers to ensure appropriate levels of confinement or disturbance and to reduce the entry of external contaminants into the system.

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
