The article mainly introduces the working principle and function of magnetic coupling rodless actuators. By reading the article, you can know that the working principle of magnetic coupling compact rodless cylinder is the same as that of ordinary double acting rodless cylinder, except that the external connection seal is different. The two sides of the cylinder are hollow. The permanent magnet in the piston rod drives the magnet outside the piston rod (moving part). Magnetic coupling electric rodless cylinder has very high requirements for the cleanliness of the working environment. The magnetic coupling guided rodless cylinder is often disassembled to clean the gasoline, which is related to its working environment.
