1.Fluorine rubber skeleton oil seal heat resistance Fluorine rubber (FPM) has good heat resistance, can be long-term work at 200-250 degrees Celsius, can also be short-term work at 300 degrees. The tensile strength and strength of fluorine adhesive decreased significantly with the increase of tem...

The skeleton oil seal is divided into three parts: self-tightening spring, sealing body and strengthening skeleton. The sealing principle of the skeleton oil seal: 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 lubric...
-
To study this problem, we assume that when the floating oil seal reduces the bevel Angle of the cone, it can reduce the pulse of the floating oil seal ring’s engagement ring caused by external impact, improve the axial force of the sealing meshing surface and keep its axial force from chan...
-
Floating oil seal can withstand the impact of greater rotation speed when used, and has a strong ability to prevent leakage and anti-fouling. The principle is that the axial force generated by the elastic deformation of the O-ring makes the end faces of the metal ring close to each other and slid...
