Pneumatic dual rod cylinders of the “SL” series are precision linear actuators. Available in “SLS” versions with piston bearings for high stress levels and “SLR” versions with ball bearings for high translation speeds, they are available in 16, 20, 25, 32 mm bores and stokes of up to 100 mm. The compact and light “SL” dual rod cylinders have special design characteristics which provide anti-rotation of the load. The high structural rigidity of the set, the force which is doubled with respected to the nominal diameter, the possibility of adjusting the return stroke and flush-fitting magnetic sensors plus a wide range of fixing solutions are just some of the features that make employment of such cylinders in a wide range of industrial automation applications easy and advantageous.
