On the Critical Speed of a Shaft at Lower Rotating Speeds
Transactions of the Japan Society of Mechanical Engineers, 1956 Since single-row radial ball bearings have small "angular clearance", the statical deflection of shaft varies with angular position of shaft provided that bearing center lines of both bearing pedestals are not in alignment and the shaft is not in a perfectly straight line.

Influence of Rotational Speed on Thermodynamic Effect in a Cavitating Inducer
, 2009 To estimate the influence of velocity on the thermodynamic effect, we conducted experiments in which the inducer rotational speed was changed in liquid nitrogen. The experiments in liquid nitrogen and in cold water allowed us to estimate the amplitude of
