Crankshaft Web Deflection

The measure of crankshaft distortion due to frame distortion or bearing misalignment. Crankshaft distortion can result in excessive cyclic stress in the crankshaft that can lead to fatigue and a shortened life. Distorted crankshafts can also cause bearing overheating, bearing failure, and problems with other moving parts with close tolerances. Web deflection measurements have proven vital in avoiding crankshaft failures.
