Roundness is an important indicator of product quality. The roundness value of bearing parts directly affects the processing benchmark between processes and the rotation accuracy, noise, vibration, life and assembly quality of the finished bearing.
The Y90G series high-speed roundness measuring instrument won the third prize of the National Invention Award. After the Y90G series instruments entered the market in the late 1990s, their product accuracy, stability and after-sales service were widely praised by users. The products are widely used in testing institutions, bearing manufacturers, scientific research institutes and bearing users.
