About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X225
The AirTAC MGCD20X225 is a double acting, double rod JIS mini cylinder with a 20 mm bore and a 225 mm stroke. Because a rod exits both covers with the same M8x1.25 male thread at each end, both sides of the piston see the rod-side area, so the output force is equal in both directions: 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 the bumper-equipped MGD, this build carries a variable air cushion at both ends, so the piston decelerates smoothly into each cover for high-speed or heavier-load stops. The through-rod also gives natural anti-rotation and a free rear rod end you can use for a stop flag or a second light load.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome plated rods for long seal and bearing life. 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, and covers 30-800 mm/s. For a realistic working load, size around 60 percent of the push force, which is roughly 8 kg horizontal; for a vertical lift, halve that to about 6 kg. This SKU has no magnet, so no position sensor can be fitted; order the -S code to enable CMSG, DMSG or EMSG switches.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X225 Is Used
High-speed anti-rotation transfer
The through-rod keeps the carried part from rotating while the variable air cushion brakes the 225 mm travel smoothly at both ends, ideal for fast pick-and-place slides carrying parts up to about 8 kg.
Twin-load press with soft stop
Rod ends on both covers let you tool up both sides of the piston, and the adjustable cushion gives a gentle landing on light pressing or staking jobs in the 131.9 N force class.
Rear-switch slide with flag
Use the rear rod end to drive a position flag or secondary actuation while the main end does the work; add the -S magnet code to fit CMSG, DMSG or EMSG switches for end-of-stroke confirmation.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X225 the Right Cylinder?
At 20 mm bore this is the smallest cushioned double-rod cylinder in the MG family, delivering 131.9 N each way at 0.5 MPa. If your load needs more force, step up to the 25, 32, 40, 50 or 63 mm bores; the 50 and 63 sizes are offered only in the cushioned MGCD and MGC types. If you want a double-rod cylinder with a fixed bumper instead of an adjustable cushion in the 20-40 range, choose the MGD; if a single rod with a cushion is enough, the MGC is the equivalent single-rod build. The variable air cushion suits higher speeds and abrupt loads, and the through-rod suits anti-rotation transfer or twin-sided tooling. Mount with the LB foot or FA flange, add I or Y rod knuckles on the moving end (SDB and CB are not available), and order the -S magnet code if you need CMSG, DMSG or EMSG sensing. The 225 mm stroke is within the 300 mm standard range for this bore; for long strokes, guide the load externally to keep side load off the 8 mm 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 MGCD20X225 FAQ
Because it is a double rod cylinder, the force is equal in both directions: 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. 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 at 30-800 mm/s, and uses an M5x0.8 port with M8x1.25 male rod threads at both ends.
The MGCD has an adjustable air cushion at both ends that decelerates the piston near each cover, allowing higher speeds and heavier loads than a plain stop; it is not a lock, so the load is not held on air loss and an external rod lock or pilot check valve is recommended for holding. The MGD is a double-rod cylinder with a fixed bumper pad instead of an adjustable cushion, and the MGC is the single-rod version with a cushion. This SKU has no magnet; the -S code enables CMSG, DMSG or EMSG sensing.
