[0002] Two separate bearings are installed in the big end of the connecting rod. These two bearings are called connecting rod bearings. The function of the connecting rod bearing is: the main function of the connecting rod bearing is to reduce the wear between the big end of the connecting rod and the connecting rod journal. The connecting rod bearing is generally made of a thin steel back and a friction-reducing alloy layer. The function of the thin steel back is to transfer the heat generated by the friction-reducing alloy to the big end of the connecting rod; the function of the friction-reducing alloy layer is to reduce the wear of the connecting rod journal and extend the service life of the journal. Materials used for connecting rod bearings: The thin steel back is generally made of high-quality low-carbon steel strips. There are many materials used for the friction-reducing alloy layer of a single-cylinder diesel engine. White alloy, steel-lead alloy, aluminum-based alloy or high-tin aluminum alloy can be selected according to the different requirements of the diesel engine.
