About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X225
The AirTAC MGCD25X225 is a double acting, double rod JIS round-body mini cylinder with a 25 mm bore and a 225 mm stroke. A 10 mm rod exits both covers with the same M10x1.25 male thread at each end, so the piston works on the rod-side area in both directions and delivers an equal 206.1 N at 0.5 MPa (288.5 N at 0.7 MPa) whether pushing or pulling. A variable air cushion at both ends decelerates the piston smoothly for higher speeds and heavier loads, and the rear rod end can carry a stop flag, position marker or a second load. Using the common rule of thumb of about 0.6 of the theoretical force, a safe vertical working load is roughly 10 kg.
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 for long service life. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates a proof pressure of 1.5 MPa (215 psi), works from -20 to +70 C, and covers speeds of 30-800 mm/s. Ports are 1/8" with PT thread as standard. The cylinder is supplied without a magnet; ordering the S code enables CMSG, DMSG or EMSG reed sensors. Mounting options are LB foot and FA flange, with I and Y rod knuckles.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X225 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from rotating while the variable air cushion allows fast 30-800 mm/s travel with smooth, jerk-free stops at both ends of the 225 mm stroke.
Twin-load press with soft stop
Rod ends on both covers let you fixture two small parts or a part and an anvil, each seeing about 206.1 N at 0.5 MPa, with the adjustable cushion easing the final approach.
Rear-switch slide (with S code)
Order MGCD25X225S so a CMSG or DMSG sensor on the rear rod end signals stroke position on slides and gates where a body-mounted switch is inaccessible.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X225 the Right Cylinder?
At 25 mm bore the MGCD25X225 gives 206.1 N each way at 0.5 MPa, so size up to MGCD32 or MGCD40 if your load needs more force, or down to MGCD20 for lighter duties. Choose this model over the MGD when you need an adjustable air cushion rather than a fixed bumper, and over the MGC when a through-rod with equal force in both directions matters. The double rod gives natural anti-rotation and a rear rod end for switches or a second load. Order the S code if you plan to fit CMSG/DMSG/EMSG sensors, and pick LB foot or FA flange mounting plus I/Y knuckles as required. For long strokes with side loads, add external guidance.

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 MGCD25X225 FAQ
Because both chambers see the rod-side area, output is equal both ways: 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), the fluid is air filtered to 40 um, temperature range is -20 to +70 C, and speed is 30-800 mm/s. Ports are 1/8" PT.
The cushion is an adjustable air cushion at both stroke ends that decelerates the piston for smooth high-speed stops; it is not a brake and will 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 MGCD cushion is adjustable, and unlike the single-rod MGC it has a rod at both ends, giving equal force in both directions. The S code magnet enables CMSG/DMSG/EMSG sensors.
