About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X350S
The AirTAC MGCD25X350S is a double acting, double-rod JIS round-body mini cylinder with a 25 mm bore and a 350 mm stroke. A hard-chrome rod exits BOTH covers with the same M10x1.25 male thread each end, so the rod-side area is effective in both directions and 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. Because the piston rod is a through rod, the rear end resists rotation and can carry a stop flag, position cam, or a second light load while the front rod does the work.
Unlike a bumper-padded build, this variant carries a VARIABLE AIR CUSHION at both ends: the adjustable throttle decelerates the piston smoothly into each cover, so you can run faster strokes or carry heavier moving mass without hard metal-to-metal stops. The barrel is SUS304 stainless with riveted covers, the piston seal is a two-way lubricant-storing type, and the fitted magnet (the S in the code) accepts CMSG, DMSG, or EMSG switches. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, -20 to +70 C, and speeds of 30-800 mm/s on air filtered to 40 um. As a rule of thumb, size the load at about 0.6 of the push force: roughly 12.6 N of side or process load, or about 10 kg in a vertical lifting duty at 0.5 MPa. Note that the 350 mm stroke exceeds the 300 mm maximum standard stroke for this bore, so it is supplied as a made-to-order length.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X350S Is Used
High-speed anti-rotation transfer
The through rod keeps a 10 kg-class carrier from twisting over the 350 mm travel while the variable air cushion eases it into each end at conveyor-line speeds, and the rear rod end carries a position flag for the CMSG switch.
Twin-load light press with soft stop
Front and rear rod ends each see the same 206.1 N at 0.5 MPa, so two small forming or marking tools can work in opposition, with the adjustable cushion absorbing the final approach instead of hammering the covers.
Rear-switch indexing slide
On a pick-and-place slide, the rear rod drives a cam past DMSG or EMSG switches for stroke-end confirmation while the cushioned stops let the 350 mm stroke cycle at speed without bounce.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X350S the Right Cylinder?
Choose the MGCD25X350S when you need equal force in both directions on a 25 mm bore with a long, cushioned 350 mm stroke: the double rod gives anti-rotation and a rear rod end for a flag or second load, and the variable air cushion protects the stroke ends at higher speeds. If your load needs more muscle, step up to MGCD32 (345.6 N each way at 0.5 MPa) or MGCD40 (527.8 N); for lighter duty, MGCD20 gives 131.9 N. If you want a double-rod cylinder with fixed bumper pads instead of an adjustable cushion in the smaller bores, look at the MGD series; if a single rod with a cushion is enough, the MGC is the equivalent single-rod build. Mount with the FA flange or LB foot, add I or Y rod knuckles for jointed loads (SDB and CB are not offered), and the fitted magnet already supports CMSG/DMSG/EMSG position sensing. The 350 mm stroke is above the 300 mm standard maximum for this bore, so expect a made-to-order build; keep side loads on the rod low at this length and guide the load externally where possible.

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 MGCD25X350S FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 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. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), the fluid is air filtered to 40 um, the speed range is 30-800 mm/s, and the temperature range is -20 to +70 C. The port is 1/8" and the rod thread is M10x1.25 at both ends.
The cushion is an adjustable air throttle at each end that decelerates the piston smoothly into the cover, so you can run faster or heavier strokes without hard stops; it is not a fixed bumper pad. It only brakes the piston near the stroke end, so the MGCD25X350S will not hold a load if air pressure is lost; add an external rod lock or pilot-operated check valve for that. The fitted magnet supports CMSG, DMSG, and EMSG switches, and compared with the MGD (double rod with bumper pads) or the single-rod MGC, this model is the cushioned double-rod choice in the JIS MG family.
