TC oil seal, which is a kind of double lip oil seal with self-tightening spring completely covered by rubber. Generally speaking, oil seal usually refers to this TC skeleton oil seal. The common materials for oil seals are: nitrile rubber, fluorine rubber and silicone rubber.
NBR
It has good heat resistance, wear resistance, resistance to various lubricants, greases, oil and gas mixtures, suitable for temperature – 30 – 120 degrees Celsius, but can no longer be used in phosphate hydraulic oil and gear oil containing extreme pressure additives, stable performance in gasoline and mineral oil with low aniline point.
FKM(Viton)
Aging resistance, heat resistance, oil resistance, almost applicable to all lubricants, fuel oils, gasoline, oil containing extreme pressure additives is not easy to harden, but cold resistance, high temperature wear resistance is poor, permanent compression deformation is large, suitable for temperature – 20 ~ 250 degrees Celsius.
Silicon rubber
It has outstanding resistance to high and low temperatures, can be used at 150 degrees Celsius for a long time without performance change, can be used at 200 degrees Celsius for 10,000 hours continuously, and can maintain its unique use flexibility, ozone resistance and weather resistance in the operating temperature range of – 70-260.
Function
Engine: crankshaft and rear oil seal, valve oil seal, transmission oil seal.
