Why Choose SFU2005 Instead of a Larger Lead Ball Screw?
For many compact machines, speed is not the only target. The 5mm lead gives SFU2005 a more controlled movement rhythm, which is useful when the machine needs steady feed, repeat positioning and lower vibration.
Best Fit For Stable Motion
Compared with 2010 or 2020 ball screws, SFU2005 moves a shorter linear distance per revolution. This helps the system gain better control during cutting, engraving, lifting or repeated positioning.
It is especially practical for equipment where accuracy, smoothness and load control matter more than very high travel speed.
