There are many types of linear modules, and there are quite a lot of dimensions. For example, according to whether they are sealed or not, they can be divided into sealed and dust-proof linear modules and semi-closed linear modules. According to the specific requirements for the size and specification of the linear module, there are quite a few parameter indicators, so the selection of the linear module is skillful.

Linear modules are also called linear modules, Cartesian coordinate robots, and linear slides. According to the drive mode, it can be divided into three categories: belt type, ball screw and linear motor, but the basic working principle is the same.
