Selection of linear slide module

The Linear Module is also called the positioning module, which is a general term for devices capable of Linear Motion in the field of automation industry.

Since different specifications affect the different structural developments of linear modules, it is not possible to unify the structure in terms of specifications.

Different application occasions and application requirements require different determination and selection. So how do you choose the right mod?

The following selection points are suggested here:

1. Load, that is, how much weight the positioning module needs to load;
2. Operating speed requirement;
3. Motion accuracy requirements: Motion accuracy refers to repetitive motion accuracy, that is, the distance between the module and the origin when it returns to the end after reciprocating 30 times.
4. Effective stroke requirements: that is, the distance from one end to the other needs to be large.

Correspondingly, when selecting a model, first refer to the above requirements to determine the detailed parameter requirements of the module:

1. In actual use, objects with heavy loads need to be measured in practice. When the load is greater than 15KG, Ball Screw drive or rack and pinion drive is required.

2. For the actual selection, the effective stroke needs to be about 50mm longer than the actual one to reserve room for expansion.

3. Manipulators with different purposes have different motion precision requirements. Generally, the motion precision of the stepping motor driven synchronous belt module can reach 0.02mm. When the servo motor drives the ball screw, the motion precision can reach 0.01mm. However, when the useful stroke is greater than 400mm, the movement accuracy will be reduced.
