About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X200
The AirTAC MGCD63X200 is a double acting, double-rod JIS round-body mini cylinder with a 63 mm bore and 200 mm stroke. A rod exits both covers with the same M18x1.5 male thread at each end, so both strokes work on the rod-side area and deliver an equal force of about 1400.9 N each way at 0.5 MPa (1961.2 N at 0.7 MPa, up to 285.7 kgf theoretical at 1.0 MPa). The variable air cushion at both ends is adjustable, letting you decelerate the piston smoothly for high-speed or heavier-duty stops instead of relying on a fixed bumper pad.
The 20 mm hard-chrome-plated steel rods resist wear and side scuffing, while the SUS304 stainless barrel with riveted covers keeps the JIS footprint compact and corrosion-resistant. Air supply should be filtered to 40 um, with an operating range of 0.15-1.0 MPa (22-145 psi), proof pressure of 1.5 MPa (215 psi), and a working temperature of -20 to +70 C at speeds of 30-800 mm/s. As a practical sizing rule, keep the vertical load to about 71 kg (roughly half of the 142 kgf thrust at 0.5 MPa). Note that the cushion only decelerates the stroke ends; it does not lock the rod, so use an external rod lock or pilot check valve if the load must be held on air loss. Add the S option to fit CMSG, DMSG or EMSG switches.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X200 Is Used
High-speed anti-rotation transfer
The 63 mm bore pushes about 1400.9 N each way at 0.5 MPa, and the adjustable air cushion tames the stop at both ends, so pallets or fixtures can be shifted at speed on the through-rod without twisting or slamming.
Twin-load press with soft stop
With an equal 1961.2 N available in both directions at 0.7 MPa and a rod end at each cover, the MGCD63X200 can press or stake two workpieces at once, with the variable cushion easing the dies into contact instead of a hard bumper hit.
Rear-switch slide with position flag
Mount a stop or cam flag on the rear rod end and, with the S option, CMSG or DMSG switches on the 200 mm stroke, giving a cushioned slide that reports end positions while the main rod carries the load.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X200 the Right Cylinder?
At 63 mm bore this is the largest MGCD size, giving 1400.9 N per direction at 0.5 MPa, so size down to the 50 mm bore (824.3 N) if your load is lighter, or step up in pressure rather than bore when you need more force from the same footprint. If you need a double-rod cylinder with a fixed bumper instead of an adjustable cushion in the smaller 20-40 mm range, look at the MGD; if a single rod with a cushion suits the task, the MGC is the equivalent single-rod type. The through-rod design gives natural anti-rotation guidance and a rear rod end that can carry a stop flag, second load or position marker. Mount with the FA flange or LB foot, and pair rod ends with I or Y knuckle joints; SDB and CB mounts are not offered on this series. Order the S suffix if you want magnet-triggered CMSG/DMSG/EMSG sensing. For strokes beyond the 500 mm standard limit or applications with significant side load, add external guides rather than relying on the rod bearings.

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 MGCD63X200 FAQ
Because it is a double-rod cylinder, the force is equal both ways: 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. 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, and covers speeds of 30-800 mm/s over a 200 mm stroke.
The cushion at each end is an adjustable air dam that decelerates the piston near the stroke end, so you can tune the stop for high speeds or heavy loads; it is not a brake and will not hold the load if air is lost, so add an external rod lock or pilot check valve for that. Unlike the MGD, which uses fixed bumper pads, the MGCD has an adjustable air cushion, and unlike the single-rod MGC it has rods at both ends, giving equal force in each direction and a rear rod end for switches or a second load. The optional S code adds a magnet for CMSG, DMSG or EMSG switches.
