【Higher Precision&Smooth Running】The trapezoidal screw belongs to sliding friction, but the ball screw is rolling friction, Through the movement of the ball, the heat is less and the precision is high，The efficiency is 2-4 times than the trapezoidal screw,which can make the Z-axis screw run more smoothly， which can make your printer capable of printing with higher precision.
【V1.5 HIGH-QUALITY Material&Accessories】Ball screw is precision machined from high strength steel, and equipped with high precision flexible coupling, special customized CNC machining screw seat, special customized CNC machining motor support，so that it has higher precision and stronger load capacity.
【Parameter Specification】1.Processing Mode：cold rolling 2.Screw diameter: 12mm 3.Pitch: 4mm 4.Lead: 4mm 5.Screw material: S55C 6.Nut material: 20CrMoV 7.Accuracy class: C7(the stroke error within any 300mm length shall not exceed 0.05mm)
Warning: This batch is not equipped with M4*14 screws, please contact us to refund US $5 as compensation.The stroke of SFU1204 is 4mm, which is different from the original T-screw,please change the pulse value from 400 to 800. If it is not changed, the printer will not be able to print.If the lead screw is a little rough at first, please turn it several times, because new mechanical products need to be run in.
