About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X225S
The AirTAC MGCD25X225S is a double acting, double rod JIS round-body mini cylinder with a 25 mm bore and a 225 mm stroke. Because a 10 mm rod exits both covers with the same M10x1.25 male thread at each end, the piston works on the rod-side area in both directions, so the output force is equal either way: about 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa, with a theoretical maximum of 42 kgf at 1.0 MPa. A variable air cushion at both ends lets you dial in smooth deceleration for higher speeds or heavier loads, and the rear rod end doubles as a mounting point for a stop, flag or second load. Applying the usual 0.6 rule of thumb, plan on roughly 124 N (about 12.6 kgf) as a safe working load per direction, or around 10 kg vertical if halving the 206.1 N figure.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with hard-chrome plated carbon-steel rods, and a two-way lubricant-storing piston seal for long service 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. The fitted magnet (the S in the code) accepts CMSG, DMSG or EMSG switches, and 1/8" ports serve both chambers. Mount it with an FA flange or LB foot, and add I or Y rod knuckles where needed.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X225S Is Used
High-speed anti-rotation transfer
The through-rod keeps both ends moving together with no rotation, while the variable air cushion tames 225 mm stops at conveyor speeds in a 206.1 N force class.
Twin-load press with soft stop
Rod ends on both covers let you load two light parts at once, and the adjustable cushion gives a gentle landing at each end of the 225 mm stroke.
Rear-switch slide
The fitted magnet and rear rod end support a CMSG/DMSG/EMSG switch flag, making this a compact cushioned slide for indexing fixtures or gates.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X225S the Right Cylinder?
Size the MGCD25X225S by its equal both-way force of 206.1 N at 0.5 MPa; step up to bore 32 or 40 if you need more, or down to bore 20 for lighter duty. If you want a double-rod cylinder without cushioning in this size range, the MGD (bore 20-40) with fixed bumpers is the alternative; if a single rod plus cushion suits the job, choose the MGC. This model's variable air cushion suits high-speed cycles and anti-rotation transfer where both rod ends must move together, and the rear rod is handy for a switch flag or a second load. Pick FA flange or LB foot mounting, add I or Y knuckles for pivoting loads, and note the fitted magnet already supports CMSG/DMSG/EMSG sensing. For long strokes like 225 mm, keep side loads off the rods and guide the load 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 MGCD25X225S FAQ
It delivers 206.1 N in each direction at 0.5 MPa and 288.5 N at 0.7 MPa, with a theoretical maximum of 42 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and speed 30-800 mm/s on air filtered to 40 um.
The variable air cushion at both ends is adjustable, so you tune the deceleration for smooth high-speed stops; it decelerates only and does not lock the load, so use an external rod lock or pilot check valve for holding. The double rod gives equal force both ways, and the S code means a magnet is fitted for CMSG, DMSG or EMSG switches. Unlike the MGD (fixed bumpers) or the single-rod MGC, the MGCD combines cushioning with a through-rod.
