What is con rod bearing?
Do you know the function of con rod bearing? (1) Poor lubrication or too small bearing clearance, causing the bearing alloy to burn out. (2) The quality of the con rod bearing itself is defective, and the alloy falls off. (3) The connecting rod journal is out of round, which reduces the contact surface between the journal and the con rod bearing, causing early loss.

What is bearing of bolts?
A cross-bolted bearing is a bearing, usually a crankshaft main bearing of a piston engine. Most bearing caps are retained by two bolts, one on each side of the bearing journal, and parallel to the cylinder axis (or, on vee engines, parallel to an axis bisecting the vee angle).
