Four Support Methods for Ball Screw

01/

Fixed-Fixed
Both ends are fixed to provide extremely high stiffness and stability, preventing axial displacement and bending of the screw.This support method provides maximum rigidity and stability, effectively reduces the deformation of the ball screw, and improves its load capacity and operating accuracy.

02/

Fixed-Sustain
One end is fixed and the other end is supported by a maintenance support, allowing a certain axial displacement to adapt to temperature changes and mechanical deformation.This method can tolerate small displacements caused by temperature changes or other factors, can adapt to certain thermal expansion, and keep the ball screw in good performance.

03/

Sustain-Sustain
Maintain supports are used at both ends to provide greater freedom and can effectively compensate for stress caused by installation errors or temperature changes.This method can provide greater flexibility and adapt to more displacement changes. It is very effective in preventing axial stress caused by thermal expansion of the ball screw.

04/

Fixed-Free
One end is fixed and the other end is free, allowing the ball screw to move freely in the axial direction, suitable for applications that require greater freedom.This method is simple and economical in structure, suitable for applications with small loads and not particularly high precision requirements.
