O-ring is a type of seal.
It is a kind of ring-shaped rubber seal, usually used to connect two or more parts in mechanical equipment.O-ring gets its name from its special oval cross-section, and its shape makes it possible for O-ring to fill the gaps of different shapes and sizes more tightly under pressure, thus effectively preventing the leakage of liquid or gas.
O-ring is usually used in automobiles, industrial equipment, household machines and electronic equipment, etc. It has a wide range of roles, low cost, easy installation and ensures reliable sealing effect.O-ring is usually made of different rubber materials, among which Viton and Styrene-Butadiene Rubber (SBR) are the two commonly used O-ring sealing ring materials, which have excellent heat resistance, corrosion resistance and aging resistance and can be used in different environments and conditions.
Classification of automobile tires
1, highway tires: also known as road tires, its design is mainly considered for use on dry, flat highways, with good driving stability, wear resistance and economic performance.
2, snow tires: also known as winter tires, which is particularly suitable for driving in the snow, ice and low temperature, with excellent anti-skid, grip performance.
3, sports car tires: also known as high-performance tires, the use of special rubber materials and structural design, with high driving stability, grip and handling performance.
4, off-road tires: these tires are usually used for off-road racing cars and off-road vehicles, which have excellent passability and wear resistance.
5, commercial tires: such as truck tires, its structural design is similar in principle to other vehicle tires, but using more wear-resistant, compression-resistant design principles.
Automobile tires are one of the important parts of the car, it directly affects the car's performance, safety and comfort. There are many types of automobile tires, according to different uses and road conditions, choose the right tire for the vehicle performance, safety and comfort have a great impact.
