The automobile crankshaft is the main component of the engine. It accepts the force transmitted by the connecting rod and converts it into torque through the output of the crankshaft and drives other subordinate work on the engine. The effect of the rotating mass centrifugal force, the periodically changing gas inertia force and the reciprocating inertia force on the crankshaft makes the crank bearing subjected to bending and torsional loads. Therefore, the accuracy of the radial roundness of the crankshaft, the roundness and the cylindricity of the crankshaft crankshaft is very high. The ex-factory price of the crankshaft is also the main factor that affects the sales of the product. For this reason, we customize the precision measuring instrument through the crankshaft non-standard to meet the needs of customers. Elek crankshaft is a professional manufacturing enterprise. The company has senior engineers engaged in crankshaft research, design, development and manufacturing, and well-known people in the same industry in the country. It is committed to the research and development of auto parts crankshafts. The crankshaft ex-factory price is also dominant in the Anhui market. Elektronik produces more than 500,000 crankshafts of various types annually, and its leading products account for more than 50% of the market in Anhui. It is a complete machine supporting product selected by JAC, Chery and other OEMs.
