Truck rear hub inner oil seal 8-94336-316-1 metal shell oil seal Size: 8011312/20

Short Description:

It is a typical representative of oil seals. Generally speaking, oil seals refer to skeleton oil seals. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the external environment, so as not to let the lubricating oil leak. The skeleton is like the steel bar in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. According to the structure, it can be divided into single-lip skeleton oil seal and double-lip skeleton oil seal. The auxiliary lip of the double-lip frame oil seal acts as a dust-proof function to prevent external dust and impurities from entering the machine. According to the frame type, it can be divided into inner frame oil seal and exposed frame oil seal
A robust hub seal with a multi-point exclusive labyrinth built into a single housing, this seal is the ultimate seal to keep elements out and oil out while minimizing friction. Unique design provides excellent contaminant removal at optimized surface velocity.

Specification

wheel hub oil seal

80*113*12/20

Hub oil seal:

Wheel hub oil seal is a daily car maintenance. The number of times the car oil seal may be replaced belongs to the auto parts with a large amount. Parts such as rolling bearings or sliding bearings are used to prevent lubricating oil or other oil leakage or leakage, etc., and can also prevent dust from infiltrating, maintain good lubrication conditions for rolling or sliding friction parts, and prolong service life.

Advantages of oil seals:

Good surface gloss, good elasticity, excellent sealing effect, good weather resistance, good material stability, customized non-standard models, mature technology, stable quality

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
