Truck oil seal sealing ring accessories 62*121*23

Short Description:

The differential oil seal is the half shaft oil seal: generally located in the lower part of the car chassis, the half shaft oil seal is used to seal and divide the two parts of the drive axle and the wheel reducer.
The axle shaft is used to transmit the output torque of the differential side gear to the drive wheel or the wheel side reducer. The oil leakage of the half shaft oil seal will reduce the amount of lubricating oil in the drive axle, affect the normal lubrication, and aggravate the wear of the parts, resulting in early damage. The oil seal of the axle shaft leaks, and the lubricating oil flows into the wheel reducer, causing the oil level of the wheel reducer to rise, breaking the oil seal and flowing into the brake drum, causing poor braking and endangering safe driving.
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.

Our advantage

    We are specialized in the manufacturing and exporting of high quality seals. Choose us is to choose the rest assured.

    We mainly produces various types, specifications, models of the seals of high precision mechanical components. We have all the specifications of what you need to help you achieve one-stop shopping, save time, effort and worry.

    We has long been a domestic and international numerous oil seal mould supply and product research and development equipment, our research and development ability, is the domestic first-class oil seal manufacturer home.

    We provide one-stop sealing solutions, and provide a full range of services, from product design, mold development, stamping skeleton, vulcanization molding, clip, screening and packaging. The entire process would take a shorter, more stable quality.

The role of the 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, as well as better heat dissipation for low-viscosity 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 ingress 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 reduce the entry of external contaminants into the system.

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
