• Protection of journal and bearing hole: One of the main functions of crankshaft bearing is to protect journal and bearing hole.
• Improve the rigidity and bending strength of the crankshaft: Fully supporting the crankshaft can improve the rigidity and bending strength of the crankshaft and reduce the load of the main bearing.
• Adjust the clearance between crankshaft and connecting rod: the crankshaft main bearing can adjust the clearance between crankshaft and connecting rod, making the engine run more smoothly.
• Bearing axial and radial loads: The crankshaft main bearing can bear axial and radial loads to balance the operation of the engine.
• Design of locating convex key and oil groove: locating convex key is made on the connecting rod bearing bush to prevent the bearing bush from moving back and forth or rotating, and at the same time, oil holes and oil grooves are made to ensure the supply of lubricating oil.
