Ellwood Crankshaft Group Component
Crankshafts and Eccentric Shafts
Custom forged and machined crankshafts and eccentric shafts, including medium-speed marine engine crankshafts for 160-500mm bore engines.
Description
Ellwood Crankshaft Group makes custom forged crankshafts and eccentric shafts in a range of shapes and sizes, supplied rough or finish machined. Crankshafts are forged on closed-die, multi-directional presses that give a continuous grain flow structure through every crank throw, which the company states gives better fatigue and impact properties than hammer or open-die forgings.
