The Ball Bush widely used in the automation field is linear motion bearing. Its plate and steel ball have a structure contacting the out diameter-housing part and inside diameter shaft respectively. Making the precise measurement of the plate thickness is important because the quality of Ball Bush is determined by the plate and steel ball. The plate thickness measurement by the Micrometer has a considerable errors in general. In order to do it, this paper proposes the AMS (Auto Measuring System) for the plate thickness measurement using LVDT(Linear Variable Differential Transformer) sensor instead of the Micrometer.
