Main & Conrod Bearing
Main & Conrod Bearing
The excavator is installed between the connecting rod and crankshaft journal to reduce friction and ensure smooth piston movement.
The engine main bearing supports the crankshaft and helps maintain stable engine rotation under heavy loads.
A reliable engine bearing system helps:
Reduce engine friction
Maintain stable oil clearance
Improve engine efficiency
Prevent abnormal wear
Extend engine service life
Proper oil lubrication and bearing tolerance are essential for preventing engine damage and maintaining performance. Engine rebuild professionals commonly emphasize checking bearing clearances to ensure correct fitment.
