Produced for automobile, truck and tractor engines, translates reciprocating linear piston motion by connecting rods into rotational motion as a result of the transforming of chemical energy into mechanical energy in the internal combustion engine. Oil channel are existed between main bearing and crank bearing on the crankshaft. Lack of the lubrication oil on the crank bearing causes friction and excessive heating, so crankshaft is damaged. At the end of the production, crankshaft’s balance setting is done. If balance setting of crankshaft is unmade, the engine works noisy and non-efficient. We have line capacity of producing crankshaft with 980 mm length and 55 mm stroke for 3, 4 and 6 cylinders engine.
