Nowadays, our hydraulic cylinder sealing materials are still based on the two original materials of nitrile rubber and polyurethane rubber. Now these two materials are no longer the previous functions and have been greatly improved. Especially the technical improvement of nitrile rubber materials has been greatly improved in the fields of high temperature resistance, low temperature resistance and wear resistance. The polyurethane rubber material has also been greatly improved in terms of hydrolysis resistance and abrasion resistance.
Another area of the hydraulic cylinder sealing ring is also significantly improved, that is, the coated sealing ring can adapt to the special working medium to be able to lower the higher or lower working temperature. At the same time, the treatment sealing ring outside of our hydraulic cylinder can also reduce The frictional resistance and adhesion to the outside of the moving parts are reduced. At the end of the editor, the problem that needs to be pointed out to everyone is that under normal circumstances, the sealing data marked by the seal manufacturers are not complete and the same, they have their own specifications, so if we need it in the actual use process Please confirm with each seal manufacturer for acceptance.
