Linear module is the first thing to consider when selecting to load this, namely load, try to choose your own close to choose load capacity, picked the great waste of resources, choose the small enough to use, is also a waste of resources, the method to calculate if it is oneself buy materials back, the first thing to understand is that the linear module is composed of what to look at the first screw type linear module, screw, ontology, guide rail sliding block, wire rod, sheet metal, etc.
In the case of stroke and the same reality screw class module will be lighter, know the part after, ask the related parameters of the suppliers of these components, and then calculated, the greater the general ontology and lead load ability is stronger, of course, if you too calculate these too much trouble, also can look for linear module manufacturers, directly with them to a manual, manual to have a variety of load parameters, you can easily choose what you need, if you still want to again a little bit lazy, can be directly consulting sales personnel, let the sales staff to help you selection.
Choose linear module is used to carry into the XYZ axis robot platform, should pay attention to the Z axis is not to choose belt type linear module, no matter how much you load is light, if you are a manufacturer also suggest that you understand clearly, with our customer of Z axis in the use of belt type linear module, the main reason is that the belt type linear module after years of Z axis use can make the belt, loose, some customers think of my load is very light, will not result in a belt, actually the client just want to when considering load in the weight of the product itself, forget the linear module and a dynamic stroma, also have the weight of the corresponding dynamic stroma, coupled with the product, the load is bigger, material of the belt itself is has the certain scale, so bad for long time use. Z axis itself is not long, the belt type linear module and screw type linear module price also is not big, so do not recommend the use of belt type linear module Z axis.
