About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X400
The MGCD32X400 is a double acting, double-rod JIS round-body mini cylinder with a variable air cushion at both ends. A 12 mm 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 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa. The adjustable air cushion decelerates the piston smoothly at each end of the 400 mm stroke, allowing higher speeds and heavier loads than an un-cushioned cylinder. Applying the usual rule of thumb of about 0.6 of the rated force, a safe working load is roughly 207 N, which corresponds to about 17 kg for a vertical lift.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and hard-chrome plated carbon-steel rod, running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s. Ports are 1/8" and the thread option is PT. Mounting is FA flange or LB foot, with I and Y rod knuckles available. This unit ships without the magnet, so no magnetic sensor can be fitted; order the S code to enable CMSG, DMSG or EMSG switches. Note that the cushion only decelerates the stroke ends and does not lock the rod: use an external rod lock or pilot check valve where the load must be held on air loss.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X400 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from twisting while the variable air cushion at both ends absorbs the stop, letting the MGCD32X400 cycle transfer slides faster than an un-cushioned cylinder.
Twin-load press with soft stop
Rod ends on both covers carry a tool or second pad, and about 345.6 N of equal force each way at 0.5 MPa plus adjustable cushioning gives a smooth, controlled press stroke.
Rear-switch slide (with S code)
On the S version, fit a CMSG, DMSG or EMSG switch on the rear rod end to flag stroke position, driving sequencing on a 400 mm cushioned slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X400 the Right Cylinder?
Size the MGCD32X400 by its equal both-way force: 345.6 N at 0.5 MPa suits mid-range cushioned double-rod duties; step up to bore 40 or 50 for more force, or down to bore 25 or 20 for lighter, compact tasks. If you need a double-rod cylinder at bore 20-40 with fixed bumper pads instead of an adjustable cushion, choose the MGD; for a single-rod cushioned cylinder, choose the MGC. The variable air cushion at both ends makes this model the right pick for high-speed or heavier-load stops, and the through-rod gives natural anti-rotation plus a rear rod end for a stop, flag or second load. Select FA flange or LB foot mounting, add I or Y knuckles as needed, and specify the S code if you plan to mount CMSG, DMSG or EMSG switches. With a 400 mm stroke on a slender rod, keep side loads low and use guides or knuckles to protect the bearings on long strokes.

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 MGCD32X400 FAQ
Because the double rod makes both sides rod-side, the force is equal both ways: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s.
The cushion is an adjustable air cushion at both ends that decelerates the piston for smooth high-speed stops; it is not a lock, so use an external rod lock or pilot check valve to hold a load on air loss. Unlike the MGD (double rod with fixed bumper pads) or the MGC (single rod with cushion), the MGCD is a double-rod cushioned cylinder with equal force in both directions. Add the S code to mount CMSG, DMSG or EMSG sensors.
