About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X75
The AirTAC MGCD25X75 is a double acting, double-rod JIS-standard round-body mini cylinder with a variable air cushion at both ends. A 10 mm rod exits both covers with the same M10x1.25 male thread, so the rod ends move together and the piston sees the rod-side area in both directions. That gives an equal output force of about 206.1 N each way at 0.5 MPa (288.5 N at 0.7 MPa), with a theoretical maximum of 42 kgf at 1.0 MPa. The adjustable air cushion decelerates the piston smoothly at each end of the 75 mm stroke, so this bore can run faster or carry heavier loads than a bumper-equipped cylinder without hard metal stops.
As a practical rule of thumb, size the working load at about 0.6 of the push force, which for this bore means roughly 12 kg safe vertical load per direction. Construction matches the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with a hard-chrome plated carbon-steel rod, a two-way lubricant-storing piston seal, and 1/8" air ports. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), temperature -20 to +70 C, and speed 30-800 mm/s. The rear rod end doubles as a mounting point for a stop, flag, or second load, and adding the optional S magnet code enables CMSG, DMSG, or EMSG position sensors.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X75 Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushion absorbs the stop, letting a 25 mm bore shuttle small parts between stations at speed without end-of-stroke impact.
Twin-load press with soft stop
Rod ends on both covers let you tool up two workpieces at once, each seeing about 206.1 N at 0.5 MPa, with adjustable cushioning easing the press into position.
Rear-switch slide
Use the rear rod end as a cam or flag driver while the front rod carries the load; add the S magnet and a CMSG or DMSG sensor for end-of-stroke confirmation.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X75 the Right Cylinder?
Choose the MGCD25X75 when you need equal force in both directions, anti-rotation guidance, and smooth cushioned stops in a compact 25 mm bore. At 206.1 N per direction at 0.5 MPa it sits above the 20 mm MGCD (131.9 N) and below the 32 mm (345.6 N), so size up if your load demands more. If you want a double-rod cylinder with a fixed bumper instead of an adjustable cushion in the 20-40 range, look at the MGD; if a single rod with a cushion is enough, the MGC is the equivalent single-rod build. Mounting options are LB foot or FA flange, with I and Y rod knuckles available (no CB or SDB). The S magnet code is required before a CMSG, DMSG, or EMSG sensor can be fitted. The maximum standard stroke for this bore is 300 mm; for long strokes, support the rod against side load.

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 MGCD25X75 FAQ
Because both sides of the piston are rod-side area, output is equal in both directions: 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa, with a theoretical maximum of 42 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to +70 C, speed is 30-800 mm/s, and the fluid must be air filtered to 40 um.
The MGCD has an adjustable air cushion at both ends that decelerates the piston near each stroke end for smooth, high-speed stops; it is not a brake and does not hold the load on air loss, so use an external rod lock or pilot check valve for holding. Unlike the MGD, which uses fixed bumper pads, the cushion here is adjustable, and unlike the single-rod MGC, the MGCD's through-rod gives equal force both ways plus a rear rod end for a stop, flag, or second load. Add the S magnet code to mount CMSG, DMSG, or EMSG sensors.
