Forged masterpieces for every torque
To achieve the high quality standards of BF forged crankshafts, most crankshafts are produced on our own tools. They are also subject to stringent test procedures. The dimensional accuracy ensures smooth running and therefore a long engine life.
The crankshaft in the engine has the task of converting the up and downstrokes of the pistons into a rotary motion with the aid of the connecting rods. The torque produced is transmitted to the fly wheel.
e.g. OM 611 4-cylinder in-line engine
e.g. OM 335 6-cylinder in-line engine
Offset conrod journals
e.g. OM 501 6-cylinder V engine
Two connecting rods per conrod journal
e.g. OM 422 8-cylinder V engine
Twisted conrod journals
Twisted: in order to realise different crank angles on the conrod journal after the die forging stage, the crankshaft is reheated at the main bearing points after forging and twisted – e.g. OM 906 6-cylinder in-line engine.
