The importance of sealing:
The main function of the oil seal is to seal. It is used to prevent the leakage of lubricating oil, hydraulic oil, coolant and other liquid media in mechanical equipment, maintain the stability of the internal oil pressure and temperature of the machine, and ensure normal operation. Machine. Oil seals can also prevent air, water and impurities from entering the machine, preventing the machine from being affected, while protecting the safety of the machine and the environment. Therefore, choosing a good oil seal is also a guarantee. Our oil seal products are of Japanese quality, and the metal casing is produced by NNK factory. Our products have absolute advantages over other companies' products. In addition, oil seals help lubricate equipment by preventing the leakage of lubricating oil, ensuring good lubrication of internal parts of the equipment, reducing friction and wear, and extending the service life of the equipment. Oil seals can also prevent sand, dust, water and gas from intruding into the bearing from the outside, limit the leakage of lubricating oil in the bearing, and play a protective role.

Truck oil seals:

Truck oil seals are a type of sealing device that are used in various trucks, buses, and other heavy-duty vehicles. These seals are designed to prevent the leakage of oil and other fluids from the engine and other vital components of the vehicle.

Function:

The function of a truck oil seal is to provide a tight and secure seal between two parts of the engine or other components that may contain oil or other fluids. These seals are typically made from rubber or other elastomeric materials that can withstand high temperatures and pressures. They are also designed to withstand friction, wear, and other forms of mechanical stress.

The primary benefits of truck oil seals include their ability to prevent oil leakage, reduce friction and wear, and increase the lifespan of critical engine parts. In addition, these seals can help improve fuel efficiency by reducing the amount of oil that is lost or wasted due to leakage.

Features:
One of the primary features of truck oil seals is their ability to withstand extreme temperatures and pressures. Most seals are made from materials that can withstand temperatures ranging from -40°C to 200°C, and pressures up to 10 bar.
Another important feature of these seals is their ability to resist abrasion, corrosion, and other forms of mechanical stress. This makes them ideal for use in heavy-duty environments where the seal must withstand constant use and exposure to the elements.

Crankshaft oil seal sealing principle

Crankshaft oil seal sealing principle :1, because there is an oil film controlled by the edge of the oil seal between the oil seal and the shaft, the oil film has fluid lubrication characteristics.Under the action of the liquid surface tension, the stiffness of the oil film just makes the contact end of the oil film and the air form a crescent surface, preventing the leakage of the working medium, so as to achieve the sealing of the rotating shaft;the sealing capacity of the oil seal depends on the thickness of the sealing surface oil film, the thickness is too large, the oil seal leakage;If the thickness is too small, dry friction may occur, causing oil seal and shaft wear;There is no oil film between the seal lip and the shaft, which is easy to cause heat and wear;therefore, in the installation, it is necessary to apply some oil on the sealing ring, while ensuring that the skeleton oil seal is vertical with the axis line, if not vertical, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive wear of the sealing lip.During operation, the lubricant in the shell exudes a little to achieve the ideal state of forming an oil film at the sealing surface.
 

Function:
Crankshaft oil seals are usually made of rubber, metal and other materials and have a soft lip-shaped structure. This structure can fit the crankshaft surface to form an effective seal and prevent lubricating oil from leaking. It is usually installed at the front end of the engine, close to the crankshaft journal.

Features:
When the engine is working, the crankshaft oil seal has to face high-speed rotation and changing working conditions, so it needs to have wear resistance, high temperature resistance, oil resistance and other properties. Damage or failure of the crankshaft oil seal may cause lubricating oil leakage and affect the normal operation of the engine, so regular inspection and replacement of the crankshaft oil seal is part of engine maintenance.

In general, the crankshaft oil seal is a key sealing component in the engine. It ensures that the lubricating oil required for the normal operation of the engine does not leak, thereby maintaining the reliability and durability of the engine.

Types and locations of crankshaft oil seals
1. Type
The crankshaft oil seal is divided into front and rear. The front crankshaft oil seal is responsible for sealing the end of the crankshaft at the timing cover end. The crankshaft rear oil seal seals the crankshaft end of the engine flywheel end.
2. Installation location
Crankshaft front oil seal: Installed on the side of the engine pulley, which is the inside of the crankshaft pulley on the side of our common generator belt.
Crankshaft rear oil seal: Installed at the connection between the engine and the gearbox, inside the flywheel. The gearbox needs to be disassembled to find it. Oil leakage is usually at the connection between the engine and gearbox.
