Frequently asked questions
What do the BK/BF12 ends mean?
The screw ends are machined to fit BK12/BF12 end-support bearing units, which hold the screw in a frame and let it rotate.
How do I connect a motor to this screw?
Use a flexible shaft coupling whose bore matches the screw end on one side and the motor shaft on the other side.
