Some of the most common oil seal material
Update:2016-05-11
When selecting the material, we must consider the compatibility of the material to the working medium, the adaptability of the working temperature range and the following ability of the lip to rotate at high speed.
◆ oil seals commonly used material:
NBR;
FKM;
Silicone;
Acrylic rubber;
Polyurethane;
PTFE;
When the general oil seal work, the lip edge temperature is higher than the working medium temperature 20~50,
Attention should be paid to selecting oil seal material. For details, please refer to the types and characteristics of rubber.
The working range of the oil seal is related to the material used for the oil seal.
◆ resistance to high temperature seal material parameters:
nitrile rubber (NBR) is -40 ~ 120 ℃,
Alec rubber (ACM) -30 ~ 180 ℃,
Fluorine rubber (FPM) -25~300.
