Ceramic Ball Check System CBCS

Fully automated quality check of surface and roundness of ceramic bearing balls

The Ceramic Ball Check System CBCS is designed to check the quality of surface and roundness of ceramic bearing balls with highest accuracy and fully automated. The most common material of ceramic bearing balls used is silicon nitride. Balls made from this material are hard, up to Rc78, and have a very smooth surface. Because of their hardness, corrosion and heat resistance, such bearing balls are well applicable in harsh environment as sea water application or steam turbines. To ensure the reliability of such bearing balls a quality check of surface smoothness and absolute roundness is essential. The CBCS proofs the zero defect production and smoothness of the surface (no cracks, scratches and flakes) of the ceramic balls and the accuracy of roundness according the precision grades listed in JIS B 1501.
