About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X200S
The AirTAC MGCD40X200S is a double acting, double rod JIS mini cylinder with a 40 mm bore and 200 mm stroke. A rod exits both covers with the same M14x1.5 male thread at each end, and because both sides of the piston see the rod-side area, the output force is equal in both directions: about 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. Both ends carry a variable air cushion, so the piston decelerates smoothly at each end of travel instead of slamming into the covers, which allows higher speeds and heavier loads. The rear rod end can carry a stop flag, a second load, or simply balance the front side.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome plated 16 mm rods, and a two-way lubricant-storing piston seal. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s. The fitted magnet (the S in the code) accepts CMSG, DMSG or EMSG switches, and the 1/8" ports take PT thread. As a rule of thumb, size the working load at about 60 percent of the push force, so roughly 32 kgf horizontal, or about 16 kg for a safe vertical lift on this 40 mm bore.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X200S Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushions absorb the energy of fast 30-800 mm/s moves, letting a 527.8 N push-and-pull slide index parts between stations without hard stops.
Twin-load press with soft stop
Front and rear rod ends each carry a small tool, giving about 527.8 N per direction at 0.5 MPa, and the adjustable cushions ease the piston down at both ends for a repeatable, gentle pressing action.
Rear-switch slide
The rear rod end mounts a cam or flag that trips the fitted CMSG/DMSG/EMSG switches, so a 40 mm bore slide with a 200 mm stroke reports both end positions while the cushions protect the covers.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X200S the Right Cylinder?
Size the MGCD40X200S when you need equal force both directions with cushioned stops at a 40 mm bore: 527.8 N each way at 0.5 MPa. If 200 mm is too long, standard strokes for this bore run up to 500 mm. For a bumper-pad double-rod cylinder without cushions at 20-40 mm bores, choose the MGD; for a single rod with a cushion, the MGC. Mount with the FA flange or LB foot, and add I or Y rod knuckles for off-axis loads; CB and SDB are not offered on this series. The fitted magnet works with CMSG, DMSG or EMSG switches. Note the cushion only decelerates the stroke ends: it is not a lock, and the cylinder will not hold its load on air loss, so add an external rod lock or pilot check valve where holding matters. For long strokes, support the load to limit side loading on the rods.

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 MGCD40X200S FAQ
Because it is a double rod cylinder, force is equal in both directions: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, with 1/8" PT ports and a maximum standard stroke of 500 mm for this bore.
The MGCD40X200S has an adjustable air cushion at both ends that decelerates the piston near each cover, allowing higher speeds and heavier loads than an uncontrolled stop; it is not a brake and will not hold the load on air loss, so use an external rod lock or pilot check valve for holding. Unlike the MGD, which is a double-rod cylinder with fixed bumper pads, the MGCD uses a variable air cushion; unlike the MGC, which is single rod, the MGCD has a rod at both ends for equal force both ways. The fitted magnet accepts CMSG, DMSG or EMSG switches.
