Rolled ball screws of accuracy grade C7 are available as standardized and stocked items.
As both shaft ends are unworked, addtitional end matching is required to meet the customized design.
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.
Rigidity selected of materials, heat treatment under optimum conditions, and advanced processing ensure outstanding durability.
Phosphate coating is applied on the nut except the flange mounting portion.
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.
Every item has been checked for axial clearance and it will be delivered as a matched pair, nut and screw shaft.
