The ultra-thin XYθ (alignment) stage "NAF3 series" is an ultra-thin stage with electric actuators arranged on the same plane, allowing for a low center of gravity for the entire device. The sliding part adopts a "preloaded double slide" structure, which sandwiches an intermediate plate between two upper and lower plates. Numerous balls are placed between each plate, enabling smooth planar rolling motion. 【Features】 ○ Ultra-thin structure and low center of gravity ⇒ By arranging three-axis actuators on the same plane, height is minimized. ○ High precision positioning ⇒ No assembly errors due to stacking, as it uses a non-stacking method. ○ High rigidity ⇒ The double slide structure supports the load as a whole, providing high rigidity against thrust direction.

The Hi-Haist Seiko rotary bearing integrated ball spline unit is a unit product that combines motion in the Z-axis (up and down) with motion in the θ-axis (rotation). By combining it with a hollow shaft, it enables operations of Z-axis × θ-axis + suction. The realization of a rotary bearing outer diameter of φ11 allows for multi-axis mounting with a 12mm pitch, contributing to the compact design (space-saving) of the equipment. Furthermore, as a unit product for delivery, it is expected to reduce the procurement of materials and the labor hours required for assembly.
