Steel rolled high precision ball leading screw; with P4,P5,P6,P7 Grade Max Diameter of ballscrew: 120mm Max Pitch from 80mm;

Precision Grinding Ground finish ball screw assembly

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 accuracyBall 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 synchronizationdue 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.

Safe use of ball screw  

Lubrication

In order to make use of function of ball screw, ball screw must be lubricated in working condition. There are following lubrication methods:

Lubrication greaseThe quantity of lubrication grease is generally 1/3 of inner space of nut. Before the ball screw leaves factory, Lithium lubrication grease GB7324-94 2# has been brought into inner space of nut.

Lubrication oilThe quantity standard of lubrication oil is shown as Tab.16. But it is changeable as difference of travel, sort of lubrication, use condition( heat control). Please pay attention.

Two ends maching processing could be done fitted for the Standard ballscrew Block;  

Each ballscrew and nut assembly will be inspected by emendation;
