About the Airtac MGD Double Rod Mini Cylinder MGD25X450S
The AirTAC MGD25X450S is a JIS-standard round-body mini cylinder, double acting and double rod: a 10 mm hard-chrome rod exits both the front and back covers with the same M10x1.25 male thread at each end. Because the rod-side area is pressurized whichever way the piston moves, 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 450 mm stroke exceeds the 300 mm maximum standard stroke for this 25 mm bore, so it is supplied as a made-to-order length.
The through-rod resists rotation and side load, keeps stroke-end position repeatable, and leaves the rear rod end free to carry a switch trip flag or drive a second load. The SUS304 stainless barrel suits damp and washdown environments, riveted covers keep the body compact, and a fixed anti-impact bumper pad decelerates the piston at each stroke end. Since the S code is fitted, CMSG, DMSG or EMSG magnetic switches can be clamped anywhere along the barrel. As a rule of thumb, size the vertical load at about 0.6 of the push force, roughly 12 kg for this cylinder at 0.5 MPa.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X450S Is Used
Anti-rotation pusher slide
The through-rod keeps a 12 kg-class pusher or gate from rotating on a 450 mm travel, holding the tool square at both stroke ends without external anti-rotation guides.
Twin-point load transfer
Front and rear M10x1.25 rod ends drive two grippers or lift points at once with equal 206.1 N force each way at 0.5 MPa, ideal for symmetric transfer of small parts.
Rear-mounted switch flag
With the magnet fitted, the back rod end carries a stop or trip flag past CMSG or DMSG switches, giving end-of-stroke signals on long 450 mm conveyor or indexing strokes.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X450S the Right Cylinder?
At 25 mm bore this sits in the middle of the MGD range: the 20 mm bore is the smallest at 131.9 N per direction, while the 40 mm is the largest at 527.8 N. If you need more force, a 50 or 63 mm bore, or an adjustable air cushion, move up to the MGCD series; for a conventional single-rod cylinder choose the MG. The 450 mm stroke is a non-standard, made-to-order length beyond the 300 mm standard maximum for this bore, so confirm lead time when ordering. The double rod is the right pick when the load can rotate on a single-rod piston, when a rear stop or flag is needed, or when one cylinder must drive two points at once. Mount with the LB foot or FA flange and add I or Y rod knuckles; SDB and CB pivot mounts are not offered on the double-rod body. For long strokes like this one, guide the load externally so side load stays off the rod bearings. Order the -S code if position sensing with CMSG, DMSG or EMSG switches is required. Note that the cylinder will not hold its load if air pressure is lost; use an external rod lock or pilot check valve where a held position matters.

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/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGD Double Rod Mini Cylinder MGD25X450S FAQ
Force is equal in both directions because the rod-side area works 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, speed range is 30-800 mm/s, and temperature range is -20 to +70 C. Ports are 1/8" on all MGD bores.
The MGD has a rod exiting both covers with the same M10x1.25 thread at each end, so it resists rotation and side load, gives equal force extending and retracting, and can drive a second load or carry a stop flag on the rear end. The single-rod MG has a larger extend force but no through-rod. This model carries the S magnet code, so CMSG, DMSG or EMSG switches can be mounted along the SUS304 barrel. Its bumper pads only soften the stroke ends; they are not an adjustable cushion, and the cylinder will not hold a load on air loss.
