Note: The data in the table is general. Some data can be specially designed according to the needs of the manufacturer. The crankshaft fatigue strength index can be based on the crankshaft

Manufacturers actually need to improve further. The amount of runout varies according to the rolling pressure of the crankshaft manufacturer, especially the crankshaft fillet is not sinking.

When pressing, the method of pressure adjustment and rolling alignment can ensure the middle neck pulsation ≤ 0.06.
