A motor is not included to this product and it must be purchased separately.
When the stroke exceeds 600mm, ball screw resonance will occur. In this case, reduce the movement speed.
Select a motor with brake for vertical use.
When the motor brand is specified as Z, the motor shaft diameter and installation dimensions must be provided.
As the drawings are schematic diagrams, please confirm the detailed dimensions according to CAD data.

Values in the table are reference values calculated according to the critical speed and DN value of the ball screw.
Values in the table are maximum safety speeds available for each stroke. As ball screws may resonate at longer strokes, such conditions as abnormal sound and vibrationmay occur when operating at the maximum speed. Therefore, the moving speed should be reduced appropriately.
