High transfer efficiency
balls with free motion transfer the force and motion between screw and nut in the ball screw assembly.
The drive torque of transfer unit reduces to 1/3 of sliding screw. This reduces the heating largely.
High positioning accuracy
Ball screw has low heat rate and small temperature increase. In the machining the measures have been taken to prolong and preload
so as to avoid axial clearance. Ball screw has high positioning accuracy and repeating positioning accuracy.
Reversibility
Ball screw has not sticky friction like sliding screw. It clears crawl which exist during transference. Ball screw can realize two transfer wise—
from rotary motion to linear motion and from linear motion to rotary motion—and transfer momentum.
Long service life
Because of strict control of shape of running track, surface hardness and material, the actual life of ball screw is much longer than sliding screw.
Good synchronization
due to smooth running, avoidance of axial clearance and consistency of manufacture, several sets of ball screw can drive same unit or several same parts. The synchronization is good.
