The spherical form error of balls, used for rolling element bearings, is measured in this paper. Conventionally, the spherical form error has been measured on the roundness meter, and the sphericity is usually evaluated with the roundnesses of several sections of the sphere. It seems that the whole measurement of the sphere surface will be necessary in accordance with the increase in an accuracy of mechanical parts. A measuring device which can traverse the whole surface of the sphere is introduced, and a calculation method which can separate the form error and the motion error is developed in this paper. Measurements of the spherical form error are carried out for steel balls, and the data are treated with the Two-dimensional Fourier transform. The calculated results are compared with the measured results of the conventional roundness meter.
