吉安奉新縣萬載美孚Mobil齒輪油-真空泵油經(jīng)銷320號齒輪油的粘度指數(shù)在300到350之間。 齒輪油的粘度等級和粘度指數(shù)是選擇齒輪油的重要參考指標。齒輪油的粘度等級一般以數(shù)字數(shù)字越大，粘度越高。而粘度指數(shù)則是指齒輪油在不同溫度下的粘度變化情況，粘度指數(shù)越高，齒輪油的穩(wěn)定性越好The viscosity index of gear oil 320 is between 300 and 350. The viscosity grade and viscosity index of gear are important reference indicators for selecting gear oil. The viscosity grade of gear oil is generally expressed in numbers, the larger the number, the higher the viscosity. The viscosity index, on other hand, refers to the viscosity change of gear oil at different temperatures, the higher the viscosity index, the better the stability of the gear oil
