A crankshaft is defined as a rotating shaft which converts reciprocating motion of the pistons into rotational motion. These are commonly used in internal combustion engines and consist of a series cranks along with crankpins, to which these connecting rods are attached. The crankshafts rotate within the engine block through their usage in the main bearings, and the crankpins tend to rotate within the connecting rods, making use of rod bearings. Crankshafts are composed of metal d the most modern crankshafts are constructed with the use of forged steel. Balu Industries is a leading crankshaft manufacturing company and aims at combining quality with precision, in all its crankshafts.
