Product Description
Product Overview
A crankshaft 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.
A crankshaft consists of crankpins, crank webs (crank arms or cheeks), balancing weights, and main journals. The large end of the connecting rod is attached to the crankpin of the crankshaft.

A crankshaft is usually manufactured of alloy steel by casting or forging process and is machined and grounded to give suitable journals for the connecting rod and main bearing.
It must be strong enough to take the thrust of the pistons during the power strokes without excessive distortion. Also, it must be carefully balanced to eliminate undue vibration resulting from the weight of the offset cranks.
