Frequently asked questions
What end supports does it need?
The screw comes with BK/BF12 end machining, which matches the standard BK12/BF12 end-support pair. Use the matching support blocks and a bearing-fitted mounting bracket at each end.
How is the screw driven?
It is typically driven by a stepper or servo motor through a flexible shaft coupling sized for the screw end. The flange nut moves along the screw and carries the load on the linear axis.
