Bearing,Con Rod(STD) Lower

The main function of excavator connecting rod bearings is to reduce the wear of the crank pin. By connecting the crank pin and the shaft, the friction between the crank pin and the shaft is effectively reduced, thereby extending the service life of the crank pin. At the same time, connecting rod bearings can improve the performance and efficiency of the engine, reduce engine noise and vibration, and ensure the normal operation and stability of the engine.
Specifically, the functions of connecting rod bearings include the following aspects:
Reduce friction and wear: By reducing the friction between the crankshaft pin and the shaft, the connecting rod bearings can lower the internal friction and wear of the engine, thereby improving the operating efficiency and stability of the engine.
Power transmission: The connecting rod bearings convert the reciprocating motion of the piston into the rotational motion of the crankshaft, providing power for the excavator.
Supporting piston: The connecting rod bearing supports the piston to move up and down in the cylinder, ensuring that the piston works in the correct position.
Shock absorption and absorption: During engine operation, the connecting rod bearings can absorb some of the impact force, reducing damage to other engine components.
In addition, the structural design of connecting rod bearings is also very important. It usually includes a cross head connecting rod big end bearing and connecting rod bolts, where the cross head connecting rod big end bearing is often made separately, while the big end bearing without a cross head connecting rod adopts an integrated design. Self adjusting or platform type connecting rod small head bearings are often used in the structure of connecting rod bearings to ensure the normal operation and stability of the engine.
