1、How to choose internal combustion engine oil （1）According to the characteristics of the internal combustion engine and the vehicle，That is, oil is selected for load and speed。High load low speed，Some large bulldozers, for example，Cranes and drilling machines, etc，Generally, lubricating oil with higher viscosity is selected，Such as SF40、CD50Etc.，Light load high speed，Like a car、Jeep、Small power equipment generally choose sticky Low degree lubricating oil，Such asSG15W/40、SF30Etc.。（2） According to internal combustion
Cause analysis of bearing damage in advance
Under normal circumstances，Flange bearings will have a natural temperature rise after just lubricating or re-lubricating and last for one to two days。Flanged bearing stability and performance vibration pairsFAGBearing damage is very sensitive，exfoliation、impression、corrosion、crack、Wear and tear will be reflected in the vibration measurement，therefore，By using a special flange bearing flange vibration gauge(Frequency analyzer)The magnitude of the vibration can be measured，The specific condition of the anomaly cannot be inferred from the frequency division。
