The crankshaft is forged from medium-carbon alloy steel such as SAE 4340 or 4140. This material has a tensile strength between 850 and 1000 MPa. Components undergo carburizing or nitriding heat treatment. This process achieves a surface hardness of 55 to 62 HRC. Dimensional tolerance for main and crank pins is between 0.010 and 0.025 mm. Surface finish for these journals requires Rq 0.1 micron or better. Static and dynamic balancing is performed with precision exceeding 1 gram-centimeter. This minimizes engine vibrations.
The crankshaft structure comprises crankpins, main journals, and crank webs. Its design features a stress concentration factor Kt below 1.5 for enhanced fatigue resistance. Fillet radii are a minimum of 3 mm with a very smooth finish. Internal oil passages typically have a diameter of 4 to 8 mm. High-speed engines utilize forged crankshafts with short fibers. These crankshafts withstand bending stress exceeding 200 MPa. Some advanced designs use roll-forging technology to compress fiber flow.

Important Points in Crankshaft Purchase and Price
Crankshaft selection must be based on the exact original part number. Material quality, including properly heat-treated alloy steel, is critical. Dimensional accuracy, including journal diameters and shaft alignment, must be verified. Authentic packaging and markings from the manufacturer indicate genuineness. The price of new original crankshafts is high due to complex manufacturing. Remanufactured samples have an average price but require precise quality control. Non-branded products with very low prices are often unreliable. Obtain a valid warranty and technical test certificate from a reputable seller.
