Differential oil seal for Mercedes Benz truck parts NBR rubber seal OEM: 0219978547 Size: 85*155*12/33

Short Description:

The differential oil seal, also known as the axle oil seal, is a device on the differential to prevent the leakage of lubricating oil.All parts that have liquid lubricating oil in the running body box and are connected to the outside need oil seals. Some are rubber, some are metal, and most are steel-bonded rubber, such as crankshaft rear oil seal, gearbox front and rear oil seals, left and right half shaft oil seals, main reducer front oil seals, air compressor crankshaft oil seals, etc.

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 main features of the oil seal

The outer part of the oil seal is cylindrical to ensure the static sealing of the cavity - the rubber outer edge with the inner metal frame is used; the outer edge of the exposed metal frame is used, and most of them need to be polished and plated with anti-corrosion coating.

The spring-loaded sealing lip guarantees the sealing reliability of the dynamic and static sealing of the shaft. As a result of long-term development and research, the sealing lip structure of the oil seal has been improved to excellent performance, thereby improving sealing reliability in a wider load range

Add a dust lip, or in special cases multiple dust lips, to prevent the intrusion of external contaminants and dust

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
