Miniature screw shaft 1204 ball screw

Miniature screw shaft 1204 Ball Screw with end machined BK12 BF12

Ball Screw Features

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 ball screw will reach more than 90%. The drive torque of transfer unit reduces to 1/3 of sliding screw. This also reduces the heat release largely.

2. High positioning accuracy

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.
3. Reversibility

Ball screw has not sticky friction like sliding screw. It clears crawl which may exists during transfer. Ball screw can achieve two transfer modes - from rotary motion to Linear Motion and from linear motion to rotary motion, and transfer momentum.
4. Long service life

Since the strict control of ball screw groove shapes, surface hardness and material selection, the actual life of ball screw is much longer than sliding screw.
5. Good synchronization

Due to smooth running, axial clearance elimination and consistency in manufacture, several sets of ball screw assembly can drive the same unit or several identical parts to obtain the good synchronization

Specification for ball screw SFU1204

The standard model for bi-directional ball screw in stock 

The characteristic of ball-screw pair

The ball screw drive system is a rolling screw drive system, in which the ball acts as the rolling medium. There are two drive modes:

         (1) transform rotary motion into linear motion.                               (2) transform linear motion into rotary motion.
