About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X250
The AirTAC MGCD63X250 is a double acting, double rod JIS round-body mini cylinder with a 63 mm bore and 250 mm stroke. A rod exits both covers with the same M18x1.5 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 1400.9 N each way at 0.5 MPa, rising to 1961.2 N at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. Unlike the bumper-equipped MGD, this variant carries a variable air cushion at both ends, so the piston decelerates smoothly into each cover for controlled high-speed stops under heavier loads.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and a hard-chrome plated 20 mm rod for corrosion resistance and long seal life. 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 speeds of 30-800 mm/s. For a realistic working load, size around 0.6 of the thrust, roughly 85 kg horizontal; for a vertical lift figure on roughly half the force, about 71 kg. The rear rod end can drive a stop flag, a second load, or a position indicator, and the cylinder is anti-rotation friendly thanks to the symmetric through-rod. Note that the cushion only decelerates the stroke ends; it is not a lock, so use an external rod lock or pilot check valve where load holding on air loss matters.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X250 Is Used
High-speed anti-rotation transfer
The through-rod keeps push and pull identical at 1400.9 N, while the variable air cushion at both ends tames 800 mm/s travel between fixtures without hard metal-to-metal stops.
Twin-load press with soft stop
Drive two small stamping or marking heads from the two M18x1.5 rod ends; the adjustable cushions give a smooth deceleration into the workpiece on each stroke end.
Rear-switch slide
Use the rear rod end to carry a cam or flag past CMSG/DMSG/EMSG switches (with the -S magnet option) for position confirmation on a 250 mm stroke slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X250 the Right Cylinder?
At 63 mm bore this is the largest MGCD size, delivering 1400.9 N per direction at 0.5 MPa; step down to MGCD50 for lighter duty or up from MGCD50 if your load stalls near 800 kgf-class thrust. If you need a double-rod cylinder without cushions in smaller bores (20-40 mm), choose the MGD; for a single rod with cushion, the MGC. The 250 mm stroke is within the 500 mm maximum standard stroke for this bore. Order the -S option if you plan to fit CMSG, DMSG or EMSG magnetic sensors; without the magnet no sensor can be mounted. Mounting options are LB foot and FA flange, with I and Y rod knuckles; PT threads are standard, with G and NPT available. For long strokes, support the rod or guide the load externally to limit side loading.

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 MGCD63X250 FAQ
Because it is a double rod cylinder, both directions produce the same rod-side force: 1400.9 N at 0.5 MPa and 1961.2 N at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), fluid is air filtered to 40 um, temperature range -20 to +70 C, and speed 30-800 mm/s.
The MGCD63X250 has a variable air cushion at both ends: adjusting screws meter exhaust air to decelerate the piston smoothly into each cover, ideal for higher speeds or heavier loads. The MGD is a double-rod cylinder with a fixed bumper instead of an adjustable cushion, and the MGC is a single-rod cushioned version with unequal push and pull forces. The cushion only decelerates at stroke ends; it does not lock the load, so add an external rod lock or pilot check valve for holding. Order the -S option to enable CMSG, DMSG or EMSG magnetic sensors.
