Rodless air cylinders differ from basic air cylinders in that no piston rod extends outside the cylinder body. Instead, the internal piston is connected to an external carriage, by means of a magnetic or mechanical coupling system.

With no external leakage, the SW series can be used in many diverse environments. Magnetically coupled cylinders have a wide range of applications, and save mounting space. Loads and moments are possible through the use of integrated guides. A variety of guides can be used to achieve the necessary accuracy or allowable moment needed for your application. SW is available in 9 bore sizes, from 6mm to 63mm with standard stokes up to 1000mm. The 5 different model variations offer widest application choice. Auto switches are integrated as standard.
