These are factory assembled XY stages for general purpose positioning applications. The stages employ rolling contact linear guide ways using crossed rollers. Friction, stick-slip and play are absent for all practical designs. These are available with lead screw drives as well as micrometer drives. Carriage (moving top) remains spring loaded by a tension spring against the micrometer spindle. This feature eliminates back-lash. In standard models, construction material used is aluminum alloy. We manufacture these products in mild steel and stainless steel as well.
