The coordinated standard ballbearing table is designed to allow 2 crossed movements at 90°. It is based on the same principle as the ES-1; the ballbearing support has two times 2 borings for the ball bearings.
The ball-bearing support and the 4 shaft supports are made of grey cast iron, ground on all sides.
The distance between the shafts is constant within 5 µm. The parallelism between the fixing bases and the shafts is within 10 µm, depending on the quality of the chosen shafts and ball bearings. Perpendicularity is 10 µm per 100 mm.
