Truck Wheel Hub Oil Seal Shaft Seal Kit Size: 85*110*115/7.5 OEM 20518611 for Truck Shaft Seal

Short Description:

The box-type oil seal is a relatively special structural form, which is different from ordinary oil seals and generally consists of two parts: an outer ring and an inner ring. The outer ring is a bit like our ordinary skeleton oil seal, but it is generally specially designed, such as positioning, dustproof, oil storage and other structures. The special part is the inner slip ring. During operation, the slip ring rotates with the rotating shaft, and the sealing lip only cooperates and rubs with the slip ring.

Features of the cassette oil seal:

The box-type oil seal is characterized by its strong anti-fouling ability and can be used in occasions with large pollution, such as heavy-duty vehicle axles, concrete machinery, agricultural machinery, etc. The life of the box oil seal is generally longer than that of the ordinary oil seal, so the replacement cycle is longer, and it is also suitable for occasions where it is difficult to replace the oil seal. The biggest advantage of the cassette oil seal is that the processing requirements for the shaft are greatly reduced. It can be seen from the structure in the figure that the sealing lip is not in contact with the surface of the shaft, so compared with ordinary oil seals, the surface roughness and surface hardness of the shaft are greatly reduced. Therefore, the overall processing cost will also be reduced.

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
