About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X200S
The AirTAC MGCD63X200S is a double acting, double-rod JIS round-body mini cylinder with a 63 mm bore and 200 mm stroke. Because a 20 mm rod exits both covers with the same M18x1.5 male thread at each end, both sides of the piston see the rod-side area, so the output force is equal in both directions: about 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. Unlike a bumper-padded build, this variant carries a variable air cushion at both ends, so the piston decelerates smoothly at each stroke end and can run at higher speeds or carry heavier loads without hard metal stops. The fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be mounted anywhere along the stainless barrel.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with hard-chrome plated rods for low wear and corrosion resistance. 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 speeds of 30-800 mm/s. For sizing, a realistic working load is roughly 0.6 of the push force, about 85 kg at 0.5 MPa; halved for a vertical lift, that is a safe figure of about 71 kg. Note that the air cushion only decelerates the stroke ends - it is not a lock - so fit an external rod lock or pilot check valve if the load must be held on air loss.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X200S Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushion soaks up the stop at each end, letting a 1400.9 N push/pull slide heavy fixtures between stations at speed without hammering the frame.
Twin-load press with soft stop
Both rod ends carry a load, so the 63 mm bore presses two parts at once with equal force each way, and the adjustable cushions give a gentle landing instead of a bang at bottom of stroke.
Rear-switch slide with position feedback
The rear rod end drives a stop or flag while the fitted magnet and a CMSG/DMSG/EMSG switch report position along the 200 mm stroke, all on a stainless barrel that shrugs off washdown.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X200S the Right Cylinder?
Choose the MGCD63X200S when you need the largest cushioned double-rod mini cylinder: 63 mm is the top of the MGCD range and delivers 1400.9 N equally in both directions at 0.5 MPa, ideal for high-speed or twin-load work where a single-rod cylinder would give unequal push and pull. If you only need a bumper-padded double rod at smaller bores, look at the MGD (20-40 mm); if you need a single rod with a cushion, the MGC is the equivalent. The 200 mm stroke is within the 500 mm maximum standard stroke for this bore, so no custom build is needed. This S-coded unit ships with the magnet fitted for CMSG/DMSG/EMSG position sensing. Mount with the FA flange or LB foot (no CB or SDB options here) and add I or Y rod knuckles on the rod ends. For long strokes or side loads, guide the load externally 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 MGCD63X200S 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. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, and the fluid is air filtered to 40 um. Ports are 1/4" and the rod thread is M18x1.5 at both ends.
The cushion is an adjustable air cushion at both stroke ends: you set the needle to decelerate the piston smoothly, which suits higher speeds and heavier loads. It only brakes the ends of travel - it does not lock or hold the load on air loss, so add an external rod lock or pilot check valve 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 cylinder with unequal push and pull forces. This S-coded unit also carries a magnet for CMSG/DMSG/EMSG switches.
