Factory direct sale wheel hub oil seal 120*150*15/20.8

Short Description:

Oil seals are often referred to as grease, fluid, dirt or lip seals. Oil seals are an integral part of any assembly of rotating and moving parts.They close the space between fixed and moving parts in mechanical equipment. In most applications, seals are either partially or temporarily immersed or simply exposed to splashes of lubricant, especially in engines, transmissions, gearboxes or axles. They are an essential part of almost all machines and vehicles in operation. Oil seals usually consist of three basic components: sealing element (nitrile rubber part), metal housing and spring. It is a widely used sealing element. The function of the seal is to prevent the leakage of the medium along the moving parts.

Specification

Wheel oil seal

120*150*15/20.8

Wheel oil seal

①Metal/rubber outer diameter
The outer diameter of the seal is designed to provide better static sealing, limited rebound effect, accurate positioning and a solid foundation for sealing in its housing, and better heat dissipation for low or high viscosity fluids.

②Pre-lubrication area
Depending on the application, apply a compatible lubricant to different areas inside the seal, which will allow for better heat dissipation, lubricate the additional sealing lip during friction and prevent the ingress of external contaminants.

③ Rubber bumper
The rubber bumper positions the sleeve correctly with the main sealing lip. They also use a variety of additional barriers to ensure appropriate levels of confinement or disturbance and to reduce the entry of external contaminants into the system.

④Main sealing lip
The main sealing lip is preloaded by a spring, ensuring optimal sealing of the medium during rotation while compensating for potential shaft runout and eccentricity failures. The optimized geometry of the sealing lip ensures reduced friction and longer product life.

⑤Metal/rubber outer diameter
The inner diameter of the seal is designed to provide a better static seal for low or high viscosity fluids and reduce installation effort during assembly.

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
