Several methods to judge the performance of linear guide rail

2018-04-13 01:36:01

There are many brands and models of linear guides on the market, so for all buyers, how to judge whether the performance of linear guides is superior is a very urgent problem. So what should we judge from? Here are some specific ways to do it.

Methods/Steps
1

High guiding accuracy: Guiding accuracy refers to the straightness of the moving part moving along the guide rail, and the accuracy of the mutual position between the bases related to it.

2

High enough rigidity: The external force of the moving parts is borne by the guide rail surface, so the guide rail should have high enough rigidity. Therefore, we often increase the width of the guide rail surface to reduce the specific pressure of the guide rail surface, and set the auxiliary guide rail to withstand the external load.

3

Smooth and lightweight guide rail movement: When the linear guide rail is working, it should be light and labor-saving, the speed is uniform, and there should be no crawling phenomenon at low speed.

4

The structural manufacturability of the guide rail is good: under the premise of ensuring the other requirements of the guide rail, the structure of the guide rail should be simple, easy to process, measure, assemble and adjust, so as to reduce costs. The guide rails used by different equipment must be analyzed in detail and the corresponding design requirements should be put forward.

6

High adaptability to temperature changes: the linear guide rail should ensure that it can still work normally under the conditions of working temperature changes.
