Several common materials and properties of Piston Rod shaft seal

Piston rod shaft seal is a common seal in industry, because of its convenient disassembly and assembly performance, by many manufacturers welcome. Therefore, in the selection of oil seals, it is necessary to pay attention to the compatibility of oil seal materials and sealing media, the adaptability to operating conditions and temperature, etc. .

Piston rod shaft seal common material:

Fluororubber material: a kind of high-temperature corrosion-resistant, oil-resistant, wear-resistant, anti-oxidation and other properties of the rubber material, combined with the skeleton and other materials made of oil seals can be long-term application at 200°c high temperature its sealing role.

NBR material: a kind of rubber material with oil resistance and oxidation resistance, chemical corrosion resistance, wear resistance and aging resistance, made of Piston Rod shaft seal is often used in the range of 120°C in a variety of common mechanical equipment seal.

Polytetra fluoroethylene material: with good chemical corrosion resistance, and not soluble in strong acid and strong Alkali and other organic solvents, made of oil seals can be used in a variety of mechanical equipment, general use temperature range of-156 ~ 250°C.

Silicone rubber, polyurethane, and other materials, there are a variety of materials, according to the actual use demand tailor-made, select the appropriate material as the main oil seal, custom made to meet the use needs of the oil seal, it can be applied to the sealing of mechanical equipment in various working conditions.

Yuanhua Piston rod shaft seal material has many kinds, according to its different performance can be made of different uses of oil seals, to meet the various operating conditions of mechanical equipment sealing requirements, sealing performance is good long service life.
