What is crankshaft pins?

Crankshaft pins are cylindrical sections of the crankshaft that attach connecting rods to the crankshaft. They are responsible for transferring the power generated by the combustion process to the rotation of the crankshaft. The number of crankshaft pins depends on the number of cylinders in the engine, with each cylinder having its own connecting rod and crankshaft pin. Crankshaft pins are typically made of high-strength steel and are precision-machined to exact tolerances to ensure proper fit and function. Proper lubrication is essential to prevent excessive wear and damage to the crankshaft pins. In high-performance engines, crankshaft pins may be forged or coated with hard materials like titanium or nitride for increased strength and durability.
