This series of bearings is based on YRTG rotary table bearings. An angular measurement system is installed on the YRTG to accurately measure and adjust the rotation angle of the bearing. The precision can reach ±1 arc-second. It is suitable for applications which need high requirements for the angle positioning accuracy.
