Stepper Motor Ball Screw Mechanism

Function of TBI anti-backlash ball screw:

Ball Screw is made of screw and ball nut . It's function is to turn the rotary

motion into linear motion.,which is a future extension and development of ball

screw. The significance of the development is to move into a rolling bearing

from  sliding action. With little frication, Ball Screw are widely used into

various industrial equipment and precision instruments.

TBI ball screw feature:

1.A small friction loss, high transmission efficiency 
There are a lot of balls rolling movement between the screw shaft and ball screw screw nut, they are able to get a higher efficiency of movement. Helpful in saving. 

2.High-precision 
Ball screw was manufactured by the world's highest level mechanical equipment, especially in the grinding, assembly, inspection of the process plant environment, temperature and humidity were strictly controlled, because of the sound quality management system so that the accuracy can be fully guaranteed. 

3.High speed feed and Micro-feed may 
Ball screw used the ball movement, so the starting torque is very small, It's doesn't appear as a sliding motion creeping phenomenon , can ensure accurate micro-feed. 

4.Axial stiffness high 
Ball screw can be adding preloading, The axial clearance can be achieve negative due to the pre-pressure , then get a higher rigidity. 

5.Due to their high efficiency,precision ball screw assemblies are in principle not self-locking. 

Specification number for TBI ball screw:

Ball screw backlash different among P0/P1/P2: 

P0: ±0.05mm to ,±0.12mm backlash is allowed in the ball screw nut. Ball screw nut can be slide down smoothly when ball screw assembly being in tilted 45 degrees. It is applied in normal automatic machines.

P1: ±0.002mm backlash is allowed in this class of backlash ball screw nut. Ball screw can be slide down slowly whenball screw assembly being in tilted 90 degrees. It is applied in high accuracy equipment and CNC. Only ball screw being machined in Beijing G.H.X Slide Hardware Products Co., Ltd can be adjusted P1 backlash for free. Ball screw not machined by us, backlash adjustment should be charged.

P2: zero backlash and -0.003 to -0.015 preload is exist. The ball screw nut can not slide down in tilted 90 degrees when being assembled, only can be moved manually; It is maily appliaed in CNC with shock and vibration state. P2 backlash will influence life of ball screw nut.
