About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X25
The AirTAC MGCD20X25 is a double acting, double-rod JIS mini cylinder with a 20 mm bore and 25 mm stroke. Because a rod exits both covers with the same M8x1.25 male thread, both directions work on the rod-side area, so the output force is equal either way: 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. At the conservative 0.6 working-load rule of thumb, that supports roughly 8 kg safely in a vertical orientation. Unlike the bumper-padded MGD, this variant carries a variable air cushion at each end, adjustable to decelerate the piston smoothly for faster cycling or heavier moving loads.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with a hard-chromed 8 mm rod, a two-way lubricant-storing piston seal, and M5x0.8 ports. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates a 1.5 MPa (215 psi) proof pressure, operates from -20 to +70 C, and cycles at 30-800 mm/s. Mount it with an FA flange or LB foot and add I or Y rod knuckles; the optional S code adds a magnet for CMSG, DMSG or EMSG switches, and strokes are standard up to 300 mm on this bore.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X25 Is Used
High-speed anti-rotation transfer
The through-rod keeps the tooling square while the variable air cushions tame fast 30-800 mm/s travel, ideal for shifting small fixtures between stations with about 131.9 N of equal force each way.
Twin-load press with soft stop
Both rod ends can carry a light pressing or marking load, and the adjustable cushion at each end decelerates the stroke smoothly instead of slamming, protecting the 20 mm bore assembly at cycle rates up to 800 mm/s.
Rear-switch slide
Use the rear rod end to drive a flag or trigger while the front rod does the work; order the S code to mount CMSG or DMSG switches for end-of-stroke confirmation on this compact 25 mm stroke slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X25 the Right Cylinder?
Size the MGCD20X25 by its equal both-way force: at 0.5 MPa it delivers about 131.9 N in either direction, so compare your load against that figure, not a single-rod push rating. Bore 20 is the smallest in the MGCD range; step up to 25, 32, 40, 50 or 63 for more force. If you need a double-rod cylinder with a fixed bumper instead of an adjustable cushion at bore 20-40, choose the MGD; for a single rod with a cushion, choose the MGC. The through-rod gives natural anti-rotation and a rear rod end you can use for a stop, flag or second load. Order the S code if you want CMSG/DMSG/EMSG magnetic sensing, pick PT (blank), G or NPT threads, and use an FA flange or LB foot with I/Y knuckles. Keep side loads off the rod on long strokes and support the tooling externally.

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 MGCD20X25 FAQ
This double-rod, double-acting cylinder produces 131.9 N in each direction 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 1.5 MPa (215 psi), temperature range -20 to +70 C, speed 30-800 mm/s, and the fluid is air filtered to 40 um. Ports are M5x0.8 and the rod thread is M8x1.25 on both ends.
The MGCD has an adjustable air cushion at both ends that decelerates the piston near each stroke end, allowing higher speeds and heavier loads than a hard stop; it is not a brake, so use an external rod lock or pilot check valve if you need position holding 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 ends, giving equal force in both directions. The optional S code adds a magnet for CMSG, DMSG or EMSG switches.
