At present, there are many kinds of linear slideways in the market. On the one hand, it gives us a wider choice space, on the other hand, it also puts forward a test to the professional level of users. However, in general, users should not worry about selection, because selection can be replaced by suppliers. The premise is that the user must provide some parameters. So, what is the main reference basis for selection?

　　一是使用条件

　　First, conditions of use

　　我们都知道使用范围很广，现在使用的不同机床和机械设备也各不相同，每台机床的加工精度也不一样，这就导致了直线导轨的配合使用也不一样。机器越粗糙，铁轨越大，也越笨重。反之，机床的加工精度越高，则使用的滑轨就是那种高精度的类型。这一点必须由用户提供给卖方，以帮助他们作出初步判断的直线幻灯片。

　　We all know that the range of use is very wide, the different machine tools and mechanical equipment used now are also different, and the machining accuracy of each machine tool is also different, which leads to the different use of linear guide. The rougher the machine, the larger and heavier the rail. On the contrary, the higher the machining accuracy of the machine tool, the type of high-precision slide rail is used. This must be provided by the user to the seller to help them make a preliminary judgment of the line slide.

　　第二,负载能力

　　Second, load capacity

　　在了解了负载能力之后，您就可以判断应该使用哪种滑块了。滑块是直线导轨上更重要的部件，它直接关系到导轨的精度水平，因此滑块的选择要非常谨慎。负荷能力也指滑块所能承受的重量，这与滑块工作时的系数有关。一般来说，只要用户在限度内选择，制造商就会给出一个负荷系数的表。

　　After you understand the load capacity, you can decide which slider to use. The slider is the most important part of the linear guide, which is directly related to the accuracy level of the guide, so the selection of the slider should be very careful. Load capacity also refers to the maximum weight that the slider can bear, which is related to the safety factor when the slider works. In general, as long as the user selects within the maximum limit, the manufacturer will give a table of maximum load safety factors.

　　第三,预期寿命

　　Third, life expectancy

　　这是影响直线上升的一个重要因素，非常重要，所以购买时要咨询一下。

　　This is an important factor that affects the straight-line rise of prices, which is very important, so you need to consult when you buy.
