About Products:

The main bearing and connecting rod bearing of the excavator engine are important bearing components inside the engine. They play a key role in supporting and transmitting engine power. The following is an introduction to the main bearings and connecting rod bearings of excavator engines:

Main bearing:

Function: The main bearing is loC-A-Ted on the main shaft of the engine to support and position the crankshaft. It can not only withstand the rotational force of the crankshaft, but also reduce the friction and wear between the crankshaft and the crankcase.
Material: The main bearing is usually made of high-strength alloy steel to ensure sufficient strength and wear resistance.
LubriC-A-Tion: Main bearings require adequate lubriC-A-Tion to reduce friction and wear. The engine lubriC-A-Tion system accomplishes this by providing the right amount of clean lubricant to the main bearings.
Connecting rod bearing:

Function: The connecting rod bearing connects the crankshaft and the piston connecting rod, withstands the reciproC-A-Ting motion and force transmission between the piston and the crankshaft, while reducing friction and wear.
Material: Connecting rod bearings are usually made of high-strength alloy steel, which has good toughness and wear resistance to cope with the requirements of high pressure and high temperature environments.
LubriC-A-Tion: Connecting rod bearings also require an appropriate amount of lubricant to reduce friction and wear. The engine lubriC-A-Tion system ensures the proper functioning of the connecting rod bearings by providing lubricant to them.

Maintenance and replacement:
Main bearings and connecting rod bearings are subjected to high loads and high temperature working environments, and may suffer from wear, fatigue and damage after long-term use. Regular inspection and maintenance of the condition of these bearings is critical to ensure engine reliability and performance. When necessary, seriously worn or damaged main bearings and connecting rod bearings need to be replaced in time.
