The NT 40 and NT 65 are normally mounted horizontally and are considered high-resolution tilting elements. The axis of rotation is determined by the center of the two accurate steel balls. The tilting angle will be adjusted using a fine-thread screw or a micrometer.
The fastening grids help combine the two-axis setups. On top of that, they can be integrated for rotary and elevator stages, translation and measuring using other OWIS components. They have fine-thread micrometers or screws and use fastening grids in table surfaces.
