Product Features of Ball Screw
1. Ball Screw drawing-based machining is no longer required, saving the time for drawing.2. Ball Screw, The total length of screw shaft can be specified in 1 mm increments. With abundant shaft end specifications, it is possible to specify alterations for different applications.
Example Use of Ball Screw

Precautions of Ball Screw
● The noise value of the Ball Screw after assembly is not guaranteed.
● Although lithium soap-based grease has been applied at the factory, it is required to apply new grease every 2~3 months as standard after receiving the goods, otherwise the normal use will be affected.
● In operation Ball Screw, if there is too much noise or sharp and harsh sound, please make sure that the installation accuracy of the screw and the specifications of peripheral components such as motors and couplings are appropriate.
● Do not let the nut exceed the movement range of the ball screw nut, or screw out of the screw shaft, otherwise the ball will fall off and the ball cycling parts will be damaged.
● Ball Screw and nuts placed with an inclination may fall due to weight. Please be careful.
● Ball Screw is a machined type, so there will be knife patterns and color difference in its appearance. Small scratches or color changes without affecting the use and main function are of a normal phenomenon. Please feel free touse.
·Removal of nut is prohibited![]() | ·No impact on the nut![]() | ·Be careful of falling due to weight![]() |
·Checking for reverse action![]() | ·Pay attention to intrusion of foreign objects![]() | ·Nut overstroke is prohibited![]() |
The ball screw is a component that only bears axial load. If it is subjected to radial load or moment load, poor sliding, vibration or abnormal noise may occur, shortening its service life.
The reason that the ball screw bears radial load and moment load is the axis deviation and parallelism error of the surrounding parts. Therefore, it is necessary to correctly design and assemble the peripheral parts of the ball screwto prevent errors.
● Axis deviation of ball screw and support unit (Fig. 1)
- Axis deviation is the deviation of the ball screw fixed by the fixed side support unit and the bearing of the supporting side support unit.
-The allowable value of the axis deviation is 20μ or less (reference value)
● Parallelism between ball screw and linear guide (Diagram 2)
- Parallelism error refers to the inclination of the ball screw in the up-down or left-right direction with respect to the reference of the linear guide.
-The allowable value of inclination is below 1/2000 (Diagram 3)
● Ball Screw Precautions of assembly
If you notice abnormal noises during the operation of the ball screw or jamming during movement after assembly, please loosen the connections of the parts before proceeding. Adjust and reassemble after moving smoothly.
- Error in the left and right direction of the support unit (Fig. 1)
- Parallel error of linear guide and ball screw (Fig. 2)
