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.

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.
