The BG actuator is an integration of precision ball screw and guide block. BG15 with a height of 15mm further contributes to compact design of machinery.
Assured accuracies are as follows.
±3microns High grade (H)
±1micron Precision grade (P)
5microns High grade (H)
2microns Precision grade (P)
As an option, positioning pin holes are provided on the sub-table and guide rail. It is useful to maintain mounting accuracy when reassembly of work table or guide rail is required.
