About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X400S
The AirTAC MGCD63X400S is a double acting, double-rod JIS round-body mini cylinder with a 63 mm bore and 400 mm stroke. A rod exits both covers with the same M18x1.5 male thread at each end, so both sides of the piston see the rod-side area and the output force is equal in both directions: about 1400.9 N each way at 0.5 MPa and 1961.2 N each way at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. Unlike a fixed bumper pad, this variant carries a variable air cushion at both ends, so needle valves let you tune the deceleration for smooth, high-speed stops under heavier loads. The magnet fitted as standard (the S code) allows CMSG, DMSG or EMSG switches to be mounted anywhere along the 400 mm travel.
Built around a SUS304 stainless barrel with hard-chrome plated rods and riveted covers, the MGCD63X400S runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi), a temperature range of -20 to +70 C and speeds of 30-800 mm/s. The through-rod gives you anti-rotation guidance and a rear rod end you can use for a stop flag, switch trigger or a second load. As a practical sizing rule, keep the working load near 60% of the push force: at 0.5 MPa that is roughly 85 kg for a vertical lift, since 1400.9 N is about 142 kgf.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X400S Is Used
High-speed anti-rotation transfer
The 400 mm through-rod guides a pallet or slider without extra rails while the variable air cushion absorbs the stop, letting the 1400.9 N force class run at the top of the 30-800 mm/s speed range.
Twin-load press with soft stop
Rod ends front and rear each drive a light pressing tool, and the adjustable cushion decelerates both strokes smoothly so parts are seated without impact at either end.
Rear-switch slide
The rear rod end trips a flag or the fitted CMSG/DMSG/EMSG switches confirm both end positions on the 400 mm stroke, while the cushion keeps reversal shock off the machine frame.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X400S the Right Cylinder?
At 63 mm bore this is the largest MGCD size, delivering 1400.9 N both ways at 0.5 MPa; step down to 50 mm if your load is lighter, or up to a larger series if you need more force. Choose the MGCD when you want a through-rod with adjustable cushioning; for a bumper-pad double rod in the smaller 20-40 mm range pick the MGD, and for a single rod with a cushion pick the MGC. Mounting is LB foot or FA flange, with I and Y rod knuckles available (no CB or SDB options). The fitted magnet supports CMSG/DMSG/EMSG position sensing. The 400 mm stroke is within the 500 mm maximum standard stroke for this bore, but at long strokes keep side loads low and use external guidance to protect 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 MGCD63X400S FAQ
Because the double-rod design exposes the rod-side area in both directions, output is equal each way: 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 63 mm bore takes a 1/4" port and M18x1.5 male rod threads at both ends.
The cushion at each end is an adjustable air chamber: you tune it with a needle valve to decelerate the piston smoothly for high-speed or heavy-load stops. It only brakes the stroke ends; it is not a lock, so the cylinder will not hold its load on air loss and an external rod lock or pilot check valve is recommended for that. The MGD is a double-rod cylinder with fixed bumper pads instead of an adjustable cushion, and the MGC is a single-rod cushioned version. This MGCD63X400S also has a fitted magnet, so CMSG, DMSG or EMSG switches can be added for position sensing.
