actuatorSingle acting cylinder

Double acting cylinder

Linear cylinders have the following standard diameters as recommended in ISO:8, 10,12,16,20,25,32,40,50,63,80,100,125,140,160,200,250,320mmCylinder sizeForce (N) = Piston area (m2) X air pressure (N /m2)Or Force (lbf) = Piston area (in2) X air pressure (lbf/in2)
