Automobile oil seal

Automobile oil seal is a mechanical component used to seal grease (oil is a very common liquid substance in the transmission system, also generally refers to the meaning of general liquid substance). cars oil seal It isolates the parts that need lubrication in the transmission parts from the output parts, so as not to let the lubricating oil leak.

There are many types of auto oil seals, NQKSF oil seal Manufacturers which can be customized for you.

EC End Cap Seals

End caps (EC for short) is also called end cap or closed cap oil seal. It is mostly used for gearbox and reducer body to prevent dust and dirt from invading the moving parts.

EC end cap seals it is mainly used for oil seal orifices, core orifices and bearings of hydraulic equipment such as engineering machinery, injection molding machinery, industrialmachinery, oil press, forklift, crane and crushing hammer. It is mainly applicable to gearbox and other components. As a substitute for end flange or end cover, the rubberlayer at the outer diameter is not easy to leak oil in the oil seal seat.

At the same time, it also strengthens the integrity and aesthetics of the gearbox and other parts.

 

Oil seal cover generally refers to the sealing cover of media containers such as gasoline, engine oil and lubricating oil in mechanical equipment.

O Ring Kit

The seal repair box is equipped with 18-32 different specifications of nitrile rubber (NBR) / silicagel (VMQ) 70 Shore a hardness \ fluororubber (FKM) 75 Shore a o ring, which is a necessary tool for mechanical maintenance.

O-Ring kits are the ideal solutioan for maintenance applications and eliminating the guesswork in part selection.

NQKSF stocks a wide variety of o ring kits repair box in various materials, styles, and sizes to address your specific needs.

O Ring NBR

O-rings are mainly used for static clearance sealing of fluids (such as water, oil, air, chemical solvents, chemicals, etc.) The long-term service temperature is – 60 ℃ to 220 ℃. Depending on the material, the static service pressure is less than 20MPa. Sometimes it can also be used for dynamic, and the service pressure in dynamic is less than 5MPa. And semiconductor vacuum seal. NQKSF o ring NBR, with a service temperature of minus 40 ° to 125 °, is resistant to mineral oil and has good wear resistance. It is most used in oil seals, but it cannot be used in ketone and lipid polar solvents. NBR rubber oring are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, ketones and many others.

There are more than 5000 models of nitrile rubber o ring seal, with sufficient inventory:

O Ring Viton

Viton is of synthetic rubber and fluoropolymer elastomer commonly used in O-rings and other molded extruded goods. The Viton o rings assortment of grades has an extremely wide temperature range and are highly resistant to chemical attacks, which makes usage in aircraft, automobiles and other mechanical devices possible. Benefits of Viton O-rings: · Wide range of chemical compatibility. · Viton orings have an extremely widetemperature range -20°C to +250°C. · Low compression set and low gas permeability. · FKM oring have excellent resistance to acids, mineral and vegetable oil and greases, fuels, aliphatic,romatic and chlorinated hydrocarbons, non-flammable hydraulic fluid and several organical sovents and chemicals. · FKM O-rings are exceptionally resistant to aging, chemical and ozone attacks.

There are more than 5000 models of NQKSF fluororubber (FKM or Viton) o seal ring materials, with sufficient inventory:

TC NBR Oil Seal

Oil seal is mainly used to seal media with pressure. It has advantages when sealing low viscosity and gaseous media.

TC type oil seal is double lip (one main lip and one auxiliary lip), one spring, and the steel framework is completely wrapped by rubber. It is used in the situation of low pressure, one side has sealing medium and the other side has slight dust. The maximum pressure is 0.03mpa (0.3kgf / cm2).

Nitrile rubber seals, with a service temperature of minus 40 ° to 125 °, is resistant to mineral oil and has good wear resistance. It is most used in oil seals, but it cannot be used in ketone and lipid polar solvents.

Fluororubber tc seal, with a service temperature of minus 20 ° to 250 °, has good heat resistance, excellent oil resistance and chemical resistance. Among all kinds of rubber, the oil seal has the best material with rubber performance balance.

There are more than 5000 models of NQKSF fluororubber (FKM or Viton) tc oil seals materials, with sufficient inventory:

VA water seal

The VA water seal is an axial rubber seal ring. Unlike general rotary oil seals, the VA water seal relies on its elastic sealing lip to form an axial sealing effect. The sealing lip has good flexibility and adaptability, so compared to other seals, it can compensate for larger deviations and angular misalignment. The function of the VA water seal is to prevent external dirt from entering and internal grease from leaking out. The intermediate connection part ensures that the sealing lip exerts a slight pressure on the sealed surface to achieve long-lasting and effective sealing.

The VA water seal is generally made of FKM (fluorocarbon rubber) material, which has excellent elasticity and is easy to stretch, making installation extremely convenient. It fits tightly with the shaft and rotates with it. Due to its simple structure, ease of use, and high reliability, the design workload related to grooves and installation is greatly reduced.

NQKSF VA water seal is widely used in industrial engineering, water treatment devices, rolling mills,lathes, and other fields.

Valve oil seal

Valve oil seal is one of the valve seals on the engine. It is used to seal the engine valve guide rod. It is a kind of oil seal.

It is required that the valve stem oil seal can withstand high and low temperature changes, high-speed rotation and other conditions. Generally, the working temperature of the valve seals can reach about 200 °. Fluororubber is commonly used to achieve good performance
