Engineering Solutions Group    Shaft Critical Speed Calculator                                     

This analysis assumes a round, solid steel shaft of a given diameter freely supported on each end by bearings. Overhung arrangements are not supported. The bearing supports are assumed to be infinitely rigid. A lumped mass may be placed anywhere between the two bearings.
