Abstract
A method of testing rotary bodies, such as balls, for ball bearings, in which the body on a layer of a coupling liquid is subjected to ultrasonic waves transmitted through the ultrasonic liquid and the reflections are measured and displayed. According to the invention the bodies are freely movable in a seat while being immersed in the liquid and jets of the liquid open tangentially into the region between the body and the seat and are intermittently pulsed so that the body undergoes multiaxial rotation.
