Ball screw selection steps

Ball screw basic selection steps and the necessary research items are as follows.

1, Decide the use conditions

Based on the weight of the moving object, feeding speed, operation mode, the screw shaft speed, stroke, installation orientation (horizontal or vertical), life time, positioning accuracy.

2, Preselect ball screw specifications

Conditions of use, preselect accuracy level of ball screw (C3 ~ C10), the screw shaft diameter, pitch, total length.

3, Confirm basic security

● Allowable axial load
Confirm axial load in the allowable axial load range of screw shaft.

● Allowable Speed
Confirm screw shaft rotational speed within the allowable range of its speed value.

● life
Calculate the life time of the screw shaft, confirm the ensured life time required.

4, According to the performance requirements for discussion

To improve the precision positioning accuracy and the control responsiveness, the need for the following confirmation.

● screw shaft rigidity
● lifetime change caused by the temperature
