About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X225
The AirTAC MGCD50X225 is a double acting, double-rod JIS round-body mini cylinder with a 50 mm bore and a 225 mm stroke. Because a 20 mm hard-chrome steel rod exits both covers with the same M18x1.5 male thread at each end, the rod-side area is effective in both directions, so the output force is equal either way: about 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. A variable air cushion at both ends lets you tune the deceleration at each end of the stroke, so the piston can run at higher speeds and carry heavier loads without hard metal-to-metal stops, while the rear rod end is free to drive a stop, flag, or a second load.
Construction follows the JIS mini-cylinder footprint with a riveted round body in SUS304 stainless and hard-chrome plated rods for long seal and bearing life. The two-way lubricant-storing piston seal keeps friction low over millions of cycles. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, -20 to +70 C, and speeds of 30-800 mm/s. As a practical working figure, apply about 0.6 of the push force, which gives a safe usable load near 494 N, or roughly 42 kg halved to about 21 kg for a vertical lift. Air ports are 1/4" PT; this no-S code has no magnet fitted, so position sensors (CMSG / DMSG / EMSG) require the optional S code.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X225 Is Used
High-speed anti-rotation transfer
The through-rod resists load rotation while the variable air cushion at both ends lets the 50 mm bore shuttle pallets at speed and stop smoothly at each end of the 225 mm stroke.
Twin-load press with soft stop
Drive two light forming or marking tools from the two rod ends with equal 824.3 N force each way at 0.5 MPa, and use the adjustable cushion to soften the impact as each tool seats.
Rear-switch slide
Use the rear rod end to carry a cam flag past CMSG or DMSG switches (with the -S magnet option) for stroke-end confirmation on a cushioned 225 mm slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X225 the Right Cylinder?
Size the MGCD50X225 by its equal both-way force: about 824.3 N at 0.5 MPa, which supports a realistic working load near 494 N (about 42 kg at 0.6 utilization, halve it to roughly 21 kg for vertical lifting). Choose this model when you need smooth, adjustable deceleration at both stroke ends plus a through-rod for anti-rotation or a rear stop/flag; if you only need a fixed bumper pad on a double-rod cylinder in a smaller bore, look at the MGD (bore 20-40), and if a single rod with a cushion is enough, the MGC covers that role. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no CB/SDB options). Add the S code if you plan to fit CMSG, DMSG, or EMSG switches. The 225 mm stroke is within the 500 mm maximum standard stroke for this bore; for long strokes, guide the load externally so side loads stay off the rod bearings.

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 MGCD50X225 FAQ
Because both sides of the piston see the rod-side area, the force is equal in both directions: 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), fluid is air filtered to 40 um, temperature range is -20 to +70 C, and speed is 30-800 mm/s. Ports are 1/4" PT and the rod thread is M18x1.5 at both ends.
Each end has an adjustable air cushion that throttles the exhaust near the end of the 225 mm stroke, decelerating the piston smoothly so you can run faster or carry heavier loads without hard stops; it only decelerates at the stroke ends and is not a brake. The MGCD does not hold its position on air loss, so fit an external rod lock or pilot check valve for load holding. Unlike the MGD (double rod with a fixed bumper pad) or the MGC (single rod with cushion), the MGCD combines a through-rod with a variable air cushion, and the optional S magnet enables CMSG, DMSG, or EMSG position sensors.
