Rear crankshaft oil seal RE44574 engine oil seal size 14511713

Short Description:

This 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 usually specially designed, such as positioning, dustproof, oil storage and other structures. Its special place is the internal slip ring. When working, the slip ring rotates with the rotating shaft, and the sealing lip only cooperates and rubs with the slip ring.

Our advantage

Crankshaft oil seal sealing principle: Since there is an oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has fluid lubrication characteristics. Under the effect of the surface tension of the liquid, the rigidity of the oil film just makes the oil film and the air contact end form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft.

Sealing ability of oil seal:

It depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak; At the same time, it is necessary to apply some oil on the sealing ring, and at the same time, ensure that the skeleton oil seal is perpendicular to the axis line. If it is not vertical, the sealing lip of the oil seal will drain the lubricating oil from the shaft, and it will also cause excessive wear of the sealing lip. During operation, the lubricant in the casing seeps out a little to achieve the ideal state of forming an oil film on the sealing surface.

material	Low TEMP.	High TEMP.	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
