Screw shaft diameter 8mm-32mm, Accuracy grade C7 (FE
series) C5 (FG series)
|
|
| Standard ground ball screw of accuracy grade C5 and C7 are available as
standardized and stocked items.As both shaft ends are unfinished, additional
machining is required to meet operating conditions. |
|
|
| High rotational speed |
| Improved with the new recirculation system named end deflector,this series
rotate by the highest speed, thus are suitable for high speed applications. |
|
| Minimize the nut size |
| The nut has much smaller length and diameter than our traditional one's. |
|
| Low noise |
| By the new recircualtion system, this has the lowest noise during its
operation. |
|
| Long life. |
| Even with its compact nut size,the basic dynamic load rating and static load
rating keep the same or higher rate than our traditional ones, therefore it can
last in a long time. |
