High transmission efficiency
Rolled ball screws have high transmission efficiency, as compared with the conventional Acme screws, and the required torque is only 1/3 less.
This makes it possible to convert linear motion to rotary motion easily.
In addition, both thread groove and nut have a Gothic-arch-shape like the ground ball screw.

Outstanding durability
Careful selection of materials, heat treatment under optimum conditions, and advanced machining techniques ensure outstanding durability.

Rustproofing
The surface of both screw shaft and nut are phosphate-coated for rust proofing.

Reasonable price
Mass production and precision thread roll die result in considerable cost reduction.

Short delivery time
This series of ball screws with unfinished shaft ends are standardized and stocked for short delivery time.
The shaft and the nut, excepting those of the miniature type, are separately sold.
