Truck half shaft oil seal 7210510/23 metal shell oil seal

Short Description:

The differential oil seal is the half-shaft oil seal: generally located in the lower part of the car chassis, the half-shaft oil seal is used to seal and divide the two parts of the drive axle and the wheel reducer.
The half shaft is used to transmit the output torque of the differential half shaft gear to the driving wheels or the wheel side reducer. The oil leakage of the axle shaft oil seal will reduce the amount of lubricating oil in the drive axle, affect normal lubrication, and aggravate the wear of parts and cause early damage. The half shaft oil seal leaks oil, and the lubricating oil flows into the wheel reducer, causing the oil level of the wheel reducer to rise, breaking the oil seal, and flowing into the brake drum, causing poor braking and endangering safe driving.

Basic information of oil seal:

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.

Product advantages:

• Excellent durability and flexibility of use.
• Special design enhances durability and length stability.
• Excellent heat, water and corrosion resistance.
• Stable performance at high speed rotation.
• Excellent special frame, resistant to heat, oil, fatigue, aging and friction.

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
