Screw shaft diameter ƒ³ 8 ~ ƒ³ 25, Accuracy grade C7
|
|
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. |
|
| Outstanding durability
|
| Rigidity selected of materials, heat treatment under optimum conditions,
and advanced processing ensure outstanding durability. |
|
| Rustproofing |
| Phosphate coating is applied on the nut except the flange mounting portion. |
|
| 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.
Every item has been checked for axial
clearance and it will be delivered as a matched pair, nut and screw shaft. |
