What does engine bearing seizure mean?

[LeRyder]

Engine bearing seizure refers to the damage of soft friction pads caused by insufficient engine oil, inadequate lubrication, or excessive load, resulting in the crankshaft being locked or partially locked. The causes of engine bearing seizure include: 1. Poor quality of engine oil with inadequate load-bearing capacity and high-temperature resistance; 2. Incorrect torque during the installation of main bearings; 3. Excessive or insufficient main bearing clearance; 4. Excessive thrust bearing clearance; 5. Malfunction of the oil pump. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (such as Stirling engines, steam engines, etc.), jet engines, electric motors, and more.
