About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X75
The AirTAC MGCD20X75 is a double acting, double-rod JIS mini cylinder with a 20 mm bore and 75 mm stroke. Because a rod exits both covers with the same M8x1.25 male thread on each end, the piston works on the rod-side area in both directions, so the output force is equal both ways: about 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, with a theoretical maximum of 26.9 kgf at 1.0 MPa. Unlike a bumper-padded build, this variant carries a variable air cushion at both ends, so you can adjust the deceleration at each stroke end for smooth, high-speed stops. The through-rod also gives natural anti-rotation and leaves a rear rod end free for a stop flag, position flag, or a second light load.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome-plated carbon steel rods, two-way lubricant-storing piston seals, and M5x0.8 ports. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands a proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C, and covers 30-800 mm/s. For a realistic working load, size around 60 percent of the push force, which puts a safe vertical figure at roughly 8 kg. Add the optional S magnet code if you later want CMSG, DMSG, or EMSG switch sensing; without it, no sensor can be mounted.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X75 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from rotating while the variable air cushion tames 75 mm stops at speed, ideal for small pick-and-place slides around 8 kg vertical rating.
Twin-load press with soft stop
Rod ends on both covers let you press two light parts at once with equal 131.9 N force per side at 0.5 MPa, while the adjustable cushions give a smooth, non-shock bottom-out.
Rear-flag switching slide
Use the rear rod end to carry a position flag or stop block; order the S magnet version to trigger CMSG or DMSG switches along the 75 mm stroke.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X75 the Right Cylinder?
Choose the MGCD20X75 when you need equal force in both directions, adjustable cushioning at both stroke ends, and a through-rod for anti-rotation or a rear stop flag in a compact 20 mm bore. At 131.9 N per side at 0.5 MPa it is the smallest MGCD size; step up to MGCD25 or MGCD32 if your load needs more force. If you want a double-rod cylinder with a fixed bumper instead of an adjustable cushion, look at the MGD (bores 20-40); if a single rod plus cushion suits your layout, the MGC is the equivalent single-rod build. Mount with the FA flange or LB foot, and pair rod ends with I or Y knuckle joints. The S code adds a magnet for CMSG/DMSG/EMSG switches. Keep side loads off the 8 mm rods on long strokes and guide external loads separately.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X75 FAQ
Output is equal in both directions: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, with a theoretical maximum of 26.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to +70 C, speed is 30-800 mm/s, and the medium is air filtered to 40 um.
The MGCD20X75 has an adjustable air cushion at both ends that decelerates the piston near each stroke end for smooth stops; it is not a lock, so use an external rod lock or pilot check valve to hold a load on air loss. Unlike the MGD, which uses fixed bumper pads, the MGCD cushion is adjustable, and unlike the single-rod MGC it has a rod at both covers, giving equal force both ways. The S magnet option enables CMSG, DMSG, or EMSG switches.
