Abstract
An apparatus wherein a spherical object is rotated on its equatorial axis (b-b) and its polar axis (a-a) adjacent a sensor (s) for detecting defects is described. The roller shaft (128) has spherical projections (129 and 130) and spaced apart parallel spindles or shafts (127) with a ball support (131) which provides centering of the spherical object or ball (B) regardless of the diameter. Preferably multiple test cage assemblies (12) are used for balls of various sizes to insure stability of the ball during testing. The apparatus is particularly used for testing of ballbearings for defects.
