Produce high quality SFK0401 ball screw for gearbox

Produce high quality SFK0401 Ball Screw for gearbox 

Ball screw is an ideal product that converts rotary motion into Linear Motion, or converts linear motion into rotary motion.
Ball screw is the most commonly used transmission element in tool Machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force. At the same time, it has both high precision, reversibility and high Features of efficiency. Because of its low frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.
The ball screw is composed of a screw, a nut, a steel ball, a pre-compression piece, a reverser, and a dustproof device. Its function is to convert rotary motion into linear motion, which is a further extension and development of Akem screw. The important significance of this development is to change the Bearing from sliding motion to rolling motion.

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
