About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X400S
The MGCD32X400S is a double acting, double-rod JIS mini cylinder with a 32 mm bore and a 400 mm stroke, built on a round SUS304 stainless barrel with riveted covers and hard-chrome plated 12 mm rods. Because a rod exits both covers with the same M10x1.25 male thread at each end, the piston works on the rod-side area in both directions, so the output force is equal both ways: 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 1/8" ports, 0.15-1.0 MPa (22-145 psi) operating range and 30-800 mm/s speed band follow the JIS mini-cylinder footprint, not ISO 6432.
What sets this variant apart is the variable air cushion at both ends plus the fitted magnet (the S code), which allows CMSG, DMSG or EMSG switches to be mounted along the barrel. The adjustable cushion decelerates the piston smoothly at each end of the 400 mm stroke, so you can run higher speeds or carry heavier moving loads without hard metal-to-metal stops, while the through-rod resists rotation and gives you a rear rod end for a stop flag or a second load. As a working rule, size around 0.6 of the push force: that is roughly 21 kg of safe vertical load for this cylinder. Proof pressure is 1.5 MPa (215 psi) and the temperature range is -20 to +70 C.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X400S Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from spinning while the variable air cushion brings the 400 mm stroke to a smooth stop at 345.6 N each way, ideal for pick-and-place slides running near the 800 mm/s top speed.
Twin-load press with soft stop
Rod ends on both covers let you tool up two workpoints, and the adjustable cushion at each end absorbs the impact, suiting light pressing or staking at this 32 mm force class.
Rear-switch slide with position feedback
With the magnet fitted, CMSG or DMSG switches ride the stainless barrel while the rear rod end drives a stop flag or counter, giving a cushioned long-stroke slide with signalling at both ends.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X400S the Right Cylinder?
Choose the MGCD32X400S when you need a cushioned, double-acting cylinder that pushes and pulls with equal force over a long 400 mm stroke in the 32 mm class. If your load needs more force, step up to bore 40 or 50; if 345.6 N at 0.5 MPa is ample, this is the efficient middle of the range (20 is smallest, 63 largest). For a double-rod cylinder with a fixed bumper instead of an adjustable cushion, look at the MGD (bores 20-40); for a single rod with a cushion, the MGC is the equivalent. The variable air cushion is set with the adjuster screws at each cover, and the through-rod gives anti-rotation for guided loads. Mount with the FA flange or LB foot (no CB or SDB options on this family) and pair rod ends with I or Y knuckle joints. The fitted magnet means CMSG, DMSG or EMSG switches can be added for end-of-stroke signalling. For strokes near the 500 mm maximum, support the rod or guide the load 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 MGCD32X400S FAQ
This 32 mm bore double-rod cylinder produces 345.6 N in each direction at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), speed range is 30-800 mm/s, temperature range is -20 to +70 C, and the fluid is air filtered to 40 um. Ports are 1/8" and the rod thread is M10x1.25 at both ends.
The cushion is an adjustable air chamber at each cover: you turn the adjuster to set how strongly the piston is decelerated at each end of the stroke, which allows higher speeds and heavier loads than a hard stop. It only slows the piston near the ends; it is not a lock, so use an external rod lock or pilot check valve if you need the load held on air loss. Unlike the MGD, which is a double-rod cylinder with a fixed bumper pad, the MGCD has an adjustable air cushion, and unlike the single-rod MGC it has a rod at both covers, so force is equal in both directions. The fitted magnet (S code) accepts CMSG, DMSG or EMSG switches.
