About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X300S
The AirTAC MGCD32X300S is a JIS-standard round-body mini cylinder, double acting, with a double rod and a variable air cushion at both ends. Because a 12 mm rod exits both covers with the same M10x1.25 male thread, the rod-side area is active in each direction, so output 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 adjustable cushion decelerates the piston smoothly at each stroke end, allowing higher travel speeds and heavier loads than an un-cushioned cylinder, while the through-rod resists rotation and gives you a rear rod end for a stop flag or a second load.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with a hard-chrome plated rod, and a two-way lubricant-storing piston seal. This -S variant carries a magnet, so CMSG, DMSG or EMSG switches can be clipped onto the 300 mm stroke for end-of-travel or mid-stroke detection. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s. As a working rule, size the load to roughly 0.6 of the push force, about 207 N, or about 17 kg for a safe vertical lift.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X300S Is Used
High-speed anti-rotation transfer
The through-rod keeps the tool plate from twisting while the variable air cushion absorbs the stop at each end, letting the 32 mm bore cycle at speed without hard impacts.
Twin-load press with soft stop
Rod ends on both covers carry two small fixtures, each seeing about 345.6 N at 0.5 MPa, and the adjustable cushion eases the press into position instead of slamming.
Rear-switch slide with flag
The rear rod end drives a position flag past a CMSG or DMSG switch, giving a second sensing point on the 300 mm stroke without extra tooling.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X300S the Right Cylinder?
Choose the MGCD32X300S when you need equal force in both directions, anti-rotation guidance and a cushioned stop on a 300 mm stroke. At 345.6 N per way at 0.5 MPa it sits in the middle of the MGCD range: step up to bore 40 (527.8 N) or 50 (824.3 N) for heavier tooling, or down to bore 25 (206.1 N) for lighter work. If you need a double-rod cylinder without cushioning in bore 20-40, the MGD with fixed bumpers is the lighter option; if a single rod plus cushion is enough, the MGC costs less. Mount with the LB foot or FA flange, and add I or Y rod knuckles on the moving end. The fitted magnet (-S) accepts CMSG/DMSG/EMSG switches. On a 300 mm stroke keep side loads low or guide the load externally.

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 MGCD32X300S FAQ
Because both strokes use the rod-side area, output is equal each way: 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. 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, on air filtered to 40 um. The bore is 32 mm with a 12 mm rod, M10x1.25 male thread on both rod ends and 1/8" ports.
The cushion is an adjustable air chamber at each cover that decelerates the piston near the stroke end, so you can tune the stop for higher speeds or heavier loads; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss. The MGD is a double-rod cylinder with fixed bumper pads instead of an air cushion, and the MGC is a single-rod cushioned cylinder. The fitted magnet on this -S model accepts CMSG, DMSG or EMSG switches.
