High Precision Ball Screw SFU1204 SFU1604 SFU2004 SFU3206 SFU5020
Product Description
High Precision Ball Screw SFU1204 SFU1604 SFU2004 SFU3206 SFU5020.The transmission efficiency of ball screw transmission system is up to 90% ~ 98%,which is 2-4 times that of the traditional sliding screw system.Ball screw can get larger thrust with smaller torque,and can also be converted from linear motion to rotational motion(reversible motion).The temperature of ball screw transmission system is small in movement,and can be tightened to eliminate axial clearance and prestretch the lead rod to compensate for thermal elongation,so high positioning accuracy and repeated positioning accuracy can be obtained.

ALM's ball screw advantages
1. High transfer efficiency
Balls with free motion in the ball screw assembly transfer the force and motion between screw and nut. This transfer mode replaces the traditional transfer mode that screw shaft and nut effect directly. Therefore the minimum rolling friction takes place of the sliding friction of traditional screw. The transfer efficiency of ALM ball screw will reach more than 90%. The drive torque of transfer unit reduces to 1/3 of sliding screw. This also greatly reduces the heat release.
2. High positioning accuracy
ALM Ball screw has low heat release, small temperature increase and with actions of pre-stretch and eliminating axial clearance in the process, which make ball screw have high positioning accuracy and repeating positioning accuracy.Positioning deviation can be 0.002mm per 300mm travel.
3. Clean and smooth,excellent surface finish
ALM Ball screw has no sticky friction.ISO management systems ensure strict performance during production and experienced talent staff combing precision machine and optimized process flow causing super quality smooth ball screw.Each ball screw will go through ultrasonic before assembly.
4. Long service life
Since the strict control of ball screw groove shapes, surface hardness and material selection, the actual life of ALM ball screw is much longer.
5. Good synchronization
Due to smooth running, axial clearance elimination and consistency in manufacturing, several sets of ball screw assembly can drive the same unit or several identical parts to obtain the good synchronization.
