Metal;Connecting Rod

The main function of excavator connecting rod bearings is to reduce the wear of crank pins, lower the friction and vibration of connecting rods. By connecting the crank pin and the shaft, the connecting rod bearing can effectively reduce the friction between the crank pin and the shaft, thereby extending the service life of the crank pin.

Specifically, the structural design of connecting rod bearings includes various forms, such as oil holes and oil grooves drilled on the inner surface of the shaft sleeve to facilitate better lubrication of lubricating oil. In addition, the connecting rod bearings can also adopt self-adjusting or platform type connecting rod small end bearings to improve performance and reliability. These designs ensure the efficient operation of the connecting rod bearings in the excavator, reducing friction and wear, thereby improving the overall performance and efficiency of the excavator
