Ball Screws
Rolled and ground ball screws with end machining to your drawing.
SFU · SFE · DFUOverview
Rolled (C7) and ground (C5) ball screws supplied with journal end machining matched to standard BK/BF support units or to drawing. Every screw is straightness-checked and matched with its nut before dispatch; nuts can be supplied separately.
Key Features
- Rolled C7 and ground C5 accuracy classes
- End machining to BK/BF or drawing
- Backlash-controlled nut matching
- Anti-rust packing for export
