Standard precision ball screws□ Model numbers of each series

Features● GP, GG, GE series: Various screw shaft diameters, leads, andaccuracy grades available for your selection• An optimal size can be selected from a variety of screw shaft diameters, leads, and accuracy
grades eliminating unnecessary compromise in product selection.

● FG, FE series: High rotational speed-1• Delivers higher rotational speed up to 5,000 min through our unique recirculation system.
• In consideration of the load rating, the products have higher specifications than previous
KURODA products.

● DP series: The industry’s smallest compact nut class• Utilizes a deflector recirculation system which realizes minimal nut dimensions.
• With leads from 1 mm, the DP series is suitable for machines and equipment that requires
fine pitch forwarding and precise positioning.

● HG series: Optimal for high-speed conveyance achieved bylarger leads• Larger leads enable a higher feed rate at a low rotational speed.
• With the adoption of multi-start thread, we have achieved a more compact nut with an
improved load rating.
