NO:1266201 Truck rubber oil seal, size 80*105*10, support OEM customized size

Short Description:

Oil seals are commonly referred to as grease, fluid, dirt, or lip seals. Oil seals are an integral part of any rotating and moving part assembly.
They close the space between fixed and moving parts in machinery. In most applications, seals are either partially or temporarily immersed or only exposed to splashed lubricant, especially in engines, transmissions, gearboxes or axles. They are an essential part of nearly every machine and vehicle in operation. Oil seals generally consist of three basic components: the sealing element (the nitrile part), the metal housing, and the spring. It is a widely used sealing element. The role of the seal is to prevent the medium from leaking along the moving parts.

Rubber oil seal


The main factors causing oil seal leakage:

Lack of tight oil seal is the main factor causing oil leakage. When the shaft is worn and grooves are formed, even if the new oil seal is replaced, the seal cannot be sealed, because the contact pressure between the oil seal lip and the shaft drops, resulting in too small interference between the oil seal lip diameter and the shaft diameter after installation.
Taking the crankshaft oil seal of the S195 diesel engine as an example, the main reasons for its poor sealing are analyzed:
① Poor manufacturing quality of oil seal;
② Shaft or bearing quality is poor;
③ Improper use and maintenance;
④ Improper installation;
⑤ Improper storage, adverse effects caused by environmental pollution

The countermeasures against oil leakage due to poor sealing of oil seal:

1. Master and identify the basic knowledge of fake and inferior products, and choose high-quality and standard oil seals.
2. During installation, if the outer surface of the shaft diameter has low roughness or has defects such as rust spots, corrosion, and burrs, it should be smoothed with fine emery cloth or oil stone; apply clean oil or lubricating grease to the lip of the oil seal or the corresponding position of the shaft diameter. Coat the outer ring of the oil seal with sealant, wrap the keyway on the shaft with hard paper to avoid scratching the lip of the oil seal, use a special tool to rotate the oil seal inward and press it in, and do not hit hard to prevent the oil seal from being deformed Or break the spring and fail; if the lip flanging occurs, the spring falls off and the oil seal is skewed, it must be removed and reinstalled. It should be noted that when the shaft diameter is not worn and the spring force of the oil seal is sufficient, do not tighten the inner spring [4] without authorization.
3. Oil seals used in machinery generally have harsh working conditions, large ambient temperature differences, a lot of dust, frequent vibrations of machinery and tools, and frequent inspection, maintenance and maintenance when the stress on the parts is constantly changing.
4. If the shaft diameter and bearing are seriously worn; the oil seal rubber is aging or the spring is invalid, etc., repair and replace the corresponding parts in time.
5. Troubleshoot abnormal heating components or assemblies in time; avoid mechanical overspeed and overload operation to prevent oil seal lip temperature rise, rubber aging, early lip wear, etc.

OEM&ODM: Custom-made samples are acceptable
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
