Long lead ball screws with a rotating nut design provide precise positioning and serve as compact solutions for linear-actuation applications requiring high speeds, low noise, and long strokes. The design allows the drive motor to move with the nut to reduce inertia, require less power, and achieve linear speeds up to 110 meters per minute. Standard versions include series SLT, which features a nut with axial play, and series BLT, which eliminates backlash. Diameters range from 25 to 50mm; leads range from 20 to 50mm, and customization options are available.
