      Information

      Bearings are only seemingly simple mechanisms. Their internal structure, a very high sensitivity to the production accuracy, type of materials used, the method of thermo-chemical treatment components, challenges us, what and how should be checked to ensure they are repeatable quality. 

      There are several steps to test the precision of bearings:

      GEOMETRIC TESTS

      Shape tests are performed on very precise machines, such as devices for measuring roundness, altimeters (photo 2, 4). Thanks to such tests we can obtain detailed results of measurements and images of ready bearing elements (photo 3). 

      The quality

       

      MATERIAL TESTS

      For material tests we are using machines and devices which make it possible to prepare the samples perfectly for the tests, they are cutters and grinders and polishers (photo 5, 6). Whereas for checking the hardness of the material we are using durometers and microdurometers (photo 7). 

       

      The quality

       

      On the right side in the photo you can see a cut bearing prepared for testing, whereas below you can see photos of elements of a bearing being prepared microstructure analysis. Starting from the left, they are: outer ring, shaft, inner ball truck and ball.
