Ball bearings are all around us. In cars, planes, wind turbines, everyday objects;
Ball bearings are precision parts that require precise and reliable control. Metro products are perfectly suited to this mission and we are present with the main players in the field.
The pneumatic measurement technique (air gage) is often used for diameter measurements on ball bearing components because of the high precision offered by this method and the absence of contact avoiding potential scratches.
The example opposite shows a manual measurement of an inside diameter of 1mm with a tolerance interval of 3µm.
