About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X50S
The AirTAC MGCD25X50S is a double acting, double-rod JIS round-body mini cylinder with a 25 mm bore and 50 mm stroke, fitted with a variable air cushion at both ends. Because a 10 mm hard-chrome rod exits both covers with the same M10x1.25 male thread, both strokes see the rod-side area, so the output force is equal in both directions: 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. The adjustable cushion decelerates the piston smoothly at each end, making this bore suitable for higher speeds or heavier moving loads than an un-cushioned mini cylinder, while the rear rod end can carry a stop flag, position marker, or a second light load.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and hard-chrome plated carbon-steel rods, and the two-way lubricant-storing piston seal reduces maintenance over long service. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a proof pressure of 1.5 MPa (215 psi), temperature range -20 to +70 C, and speed range 30-800 mm/s on air filtered to 40 um. The magnet fitted by the S code allows CMSG, DMSG, or EMSG switches to be mounted for end-of-stroke detection. For a realistic working load, apply the usual 0.6 rule of thumb to the 206.1 N push force: about 12 kg safe vertical load at 0.5 MPa.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X50S Is Used
Anti-rotation high-speed transfer
The through-rod resists load rotation while the variable air cushion at both ends tames stops at conveyor transfer speeds, moving small pallets or trays with about 206.1 N available in either direction at 0.5 MPa.
Twin-load light press with soft stop
Rod ends on both covers let one cylinder carry two light pressing or marking points that move together, and the adjustable cushion gives a smooth, non-shock landing on each stroke for delicate assembly work.
Rear-switch slide with magnet
With the fitted magnet and a CMSG or DMSG switch on the rear rod side, this 25 mm bore slide drives a small indexing fixture and confirms position, while the cushion keeps end-of-stroke impact low at 30-800 mm/s.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X50S the Right Cylinder?
Size the MGCD25 by force, not bore alone: at 206.1 N per direction at 0.5 MPa it sits between the 20 (131.9 N) and 32 (345.6 N); step up to MGCD32 if your load margin is tight, or down to MGCD20 for lighter duty. Choose the MGCD over the MGD when you need adjustable deceleration at both ends rather than fixed bumper pads, and over the single-rod MGC when equal force both ways, anti-rotation, or a rear rod end for a stop flag matters. The S in MGCD25X50S means the magnet is already fitted, so order CMSG, DMSG, or EMSG switches for sensing; without the S code no sensor can be mounted. Mount with the FA flange or LB foot, and use I or Y rod knuckles on the rod ends; CB and SDB mounts are not offered on this series. Standard strokes for bore 25 run up to 300 mm, so 50 mm is a standard build. Keep side loads off the rod on long strokes and guide external mass separately.

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 MGCD25X50S FAQ
Because the double-rod design exposes the rod-side area on both strokes, force 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), temperature range is -20 to +70 C, speed is 30-800 mm/s, and the fluid is air filtered to 40 um. The bore is 25 mm, stroke 50 mm, rod 10 mm with M10x1.25 male threads on both ends, and the port is 1/8".
The cushion at each end is an adjustable air chamber that decelerates the piston just before the stroke end, so you can tune the stop for higher speeds or heavier loads; it is not a brake and does not 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 air cushion; unlike the single-rod MGC, the MGCD has a rod at both ends, giving equal force in both directions and a rear rod end for a stop flag or second load. The fitted S magnet also accepts CMSG, DMSG, or EMSG switches.
