About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X200
The AirTAC MGCD25X200 is a double acting, double-rod JIS mini cylinder with a 25 mm bore and 200 mm stroke. Because a 10 mm 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 either way: about 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. A variable air cushion at both ends lets you tune the deceleration for smooth, high-speed stops, and the through-rod gives natural anti-rotation plus a rear rod end you can use for a position flag or a second light load. As a practical rule of thumb, keep the working load to about 0.6 of the push force, roughly 124 N, which for a vertical lift means a safe figure of about 10 kg.
Construction follows the JIS round-body mini cylinder format: a riveted SUS304 stainless barrel with hard-chrome plated carbon-steel rods, and a two-way lubricant-storing piston seal for long service life. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands a proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C, and covers speeds of 30-800 mm/s. Ports are 1/8". Mounting options are the FA flange and LB foot, with I and Y rod knuckles available; the optional S code adds the magnet required for CMSG, DMSG or EMSG switches. This model ships without the magnet, so no sensor can be mounted unless you order the -S variant.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X200 Is Used
High-speed anti-rotation transfer
The through-rod keeps the payload from twisting during fast 200 mm shuttles, while the variable air cushion at each end absorbs the stop at speeds up to 800 mm/s.
Twin-load press with soft stop
Both rod ends carry a small tool or pad, delivering about 206.1 N each way at 0.5 MPa, and the adjustable cushion gives a gentle landing on delicate parts.
Rear-switch slide
Use the rear rod end to drive a flag past a CMSG or DMSG switch (order the -S magnet option) for position confirmation on a light indexing slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X200 the Right Cylinder?
Size the MGCD25X200 by force, not bore alone: at 206.1 N per direction at 0.5 MPa it suits light transfer, positioning and twin-load tasks; step up to MGCD32 or MGCD40 when you need 345.6 N or 527.8 N, and down to MGCD20 for the smallest envelope. If you need a double-rod cylinder at bores 20-40 with a fixed bumper instead of an adjustable cushion, choose the MGD; if a single rod with a cushion is enough, the MGC covers that. The 200 mm stroke is within the 300 mm standard range for this bore, so no nonstandard surcharge applies. Order the -S option if you plan to fit CMSG, DMSG or EMSG switches, and pick FA flange or LB foot mounting plus I or Y knuckles to match your fixture. For long strokes with side loads, add external guidance rather than loading the rod laterally.

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 MGCD25X200 FAQ
It is double acting with a double rod, so the force 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. Ports are 1/8" and the rod thread is M10x1.25 at both ends.
The cushion is an adjustable air cushion at both stroke ends: you regulate the orifice to decelerate the piston smoothly, which suits higher speeds and heavier loads. It only slows the piston near the end; it does not lock or hold the load on air loss, so add an external rod lock or pilot check valve for holding. Unlike the MGD, which uses fixed bumper pads, the MGCD has this adjustable cushion; unlike the single-rod MGC, the MGCD has a rod at both ends, giving equal force both ways and a rear rod end for a flag or second load. The -S option adds the magnet needed for CMSG, DMSG or EMSG switches.
