Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X500

The AirTAC MGCD50X500 is a double acting, double rod JIS-standard round-body mini cylinder with a 50 mm bore and a 500 mm stroke, the maximum standard stroke for this bore. A hard-chrome 20 mm rod exits BOTH covers with the same M18x1.5 male thread at each end, so the two rod ends travel together and the effective area is the rod-side area in either direction. That means the output force is identical both ways: about 824.3 N (84 kgf) at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. Unlike a bumper-padded build, this variant carries a variable air cushion at both ends, so you can dial in the deceleration to suit your speed and load.

The through-rod design gives you a rear rod end you can use for a position flag, a stop plate or a second light load, and it resists side rotation without extra guides. For a realistic working figure, plan on roughly 60 percent of the push force, about 495 N (50 kgf), or a safe vertical lift of around 42 kg at 0.5 MPa. The barrel is SUS304 stainless and the rods are hard-chrome carbon steel, the covers are riveted and rolled, and the piston seal stores lubricant for long service. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates a proof pressure of 1.5 MPa (215 psi), works from -20 to +70 C at 30-800 mm/s, and ports are 1/4". Note that the cushion only decelerates the piston at each end; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss.
