Magnetically coupled rodless cylinder, referred to as rodless cylinder or rodless actuator, the biggest difference between it and regular cylinder is that there is only a piston in the rodless cylinder and no piston rod, while the regular cylinder contains both a piston and a piston rod. As a professional manufacturer, we would like to provide you with Rodless Magnetic Coupling Guide Pneumatic Air Cylinder. And we will offer you the best after-sale service and timely delivery. The working principle of a rodless air cylinder is: install a group of high-strength magnetic permanent magnetic rings on the piston, and the magnetic lines of force interact with another group of magnetic rings sleeved outside through the thin-walled cylinder. Because the two groups of magnetic rings have opposite magnetic properties, they have a strong suction force from each other. When the piston is pushed by air pressure in the cylinder, under the action of the magnetic force, the magnetic ring sleeve outside the cylinder is driven to move together.
