There are various types of Crankshaft offered by us that is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine is attached. It works on the crank mechanism. A crank has crankpins and cranks which are connected with the connecting rods. It is an essential part of the power transmission system. In which, the reciprocating movement of the piston is converted into the rotating movement by using the connecting rod. The Crankshaft is used to convert the linear motion of a piston in rotary motion.
