SFU1605 300MM Ball Screw Upgrade Kit With BK12 And BF12 End Mounts, DSG16H Anti Backlash Nut, SBR16 Linear Rails, UU Bearing Blocks, And 6.35X10MM Couplings For Slick CNC Runs And Solid Motion

SFU1605 CNC Ball Screw Kit With Linear Rails And End Mounts
✔️ GCr15 steel C7 precision BK12 BF12 blocks DSG16H nut couplings

This complete upgrade kit swaps dead drive components for smooth sliding action on your DIY CNC router. You get matched pairs of SBR16 guide rails paired with low friction UU bearing blocks for consistent axis movement. The rolled thread design drops noise levels and handles heavy cuts without letting your tools wander off target.

✅ SFU1605 ball screw shaft reaches three hundred millimeters overall length
✅ DSG16H anti backlash nut locks tightly to stop play during precise routing
✅ BK12 and BF12 end support blocks include locknuts and circlips for secure mounting
✅ Six point three five by ten millimeter couplings absorb vibration from motor mounts
✅ Four UU bearing sliders grip the thirty millimeter SBR16 linear rails smoothly

💡 How does a ball screw upgrade improve CNC machine accuracy? Improving your slide system is a handy upgrade that boosts repeatability and saves your stepper motors from excessive strain. - Rolled thread C7 class screws maintain tight pitch tolerances for repeatable X Y Z axis movement. - Anti backlash linear nuts prevent gear lash when switching cutting direction during pocket milling. - Standard block mount patterns fit common aluminum extrusion profiles without custom drilling. - Heavy duty rubber couplings isolate motor torque peaks to protect sensitive control boards.
