Requirements for the performance of hydraulic cylinder sealing materials

The selection of hydraulic cylinder sealing material is a very important part. If you did not pay attention to the previous selection, there will be a lot of problems in the subsequent use process. I hope everyone will not ignore this important part and pay more attention to it. Some knowledge of use, this will do the job better.

Although hydraulic cylinder sealing materials are still mainly nitrile rubber and polyurethane rubber, their performance has been greatly improved. The technical progress of nitrile rubber materials is mainly manifested in high temperature resistance, low temperature resistance and wear resistance, while polyurethane The technical progress of rubber materials is mainly manifested in hydrolysis resistance and wear resistance.

The performance of the support ring is also getting better and better, which is mainly the result of the improvement of material performance. The combined use of various sealing materials improves the overall performance of the seal and makes it more resistant to extrusion and wear. High pressure resistance and better sealing performance. The working temperature of high temperature resistant nitrile rubber can be in the range of -25~150℃. The working temperature of low temperature resistant nitrile rubber can be in the range of -45~100℃.
