Hiwin HG Series Linear Rails

There are many types of linear modules, and the dimensions of division are quite appropriate. For example, according to whether they are sealed or not, they can be divided into sealed dust-proof linear modules and semi enclosed linear modules. Based on the specific size specifications of the linear module, there are also quite a few parameter indicators, so the selection of linear modules is skillful. Below, the editor has compiled seven precautions for selecting linear modules for your reference:

1. Vibration resistance and stability

The precision linear module and heavy-duty linear module used require higher vibration resistance and stability. One is high precision requirements, and the other is that there may be vibrations and significant external forces in the usage environment.

2. Stiffness

Stiffness is an indicator, and the accuracy of linear modules is also related to stiffness. Improving stiffness can be considered from various aspects such as material use and preloading.

If the model cannot meet the requirements, it may need to be customized.

3. Motion sensitivity and positioning accuracy

4. Accuracy retention

Linear modules have precision levels, and the prices of different levels of linear modules are different. Choosing the corresponding level of accuracy is more important, otherwise either the accuracy is too low to meet the usage requirements, or the accuracy is too high, wasting costs.

5. Guidance accuracy

Guidance accuracy is just one of the parameters in the accuracy of linear guides.

6. Smoothness of motion

Smooth movement is a basic requirement, which may be related to installation accuracy, but also to the linear module itself, lubrication, vibration, and external forces.

7. Selection of motor

Different brands of linear modules will have their own motors, and the choice of motor depends on the brand of linear module used.
