Airtac MG Stainless Steel Mini Air Cylinder MG25X225S
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG25X225S is a genuine double acting JIS-standard round-body mini air cylinder with a Ø25mm bore and 225mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MG Stainless Steel Mini Air Cylinder MG25X225S
With a 25 mm bore pushing 245.3 N at 0.5 MPa (343.4 N at 0.7 MPa), this MG25X225S is a double acting JIS round-body mini cylinder with a 225 mm stroke and a built-in magnet. Air drives the rod out and back, the 1/8" ports feed both chambers, and a fixed anti-impact bumper pad at each stroke end softens the direction change. The riveted SUS304 stainless barrel with a hard-chrome plated 10 mm rod shrugs off washdown and damp shop air far better than painted-steel minis.
For sizing the real job, treat roughly 147 N (about 0.6 of the 0.5 MPa push) as the usable working force, which means this cylinder lifts about 12 kg vertically with a 2:1 margin. Because the magnet is factory-fitted, CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke signalling without any rework. Note that the bumpers only decelerate the stroke end - with air off or the valve centred the rod drifts, so hold external loads with a rod lock or pilot check valve.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X225S Is Used
Packaging line pusher
Ejecting cartons or trays sideways off a conveyor at 30-800 mm/s, where the 245.3 N push at 0.5 MPa clears a 10 kg product stream and the magnet signals home position to the PLC.
Small parts press station
Light press-fitting of bushings or labels into plastic housings, using the roughly 147 N usable working force and the bumper pads to soften the return stroke at cycle end.
Lab sample handling gate
Driving a slide gate or diverter in a stainless-washdown analytical or food sampling rig, where the SUS304 barrel and 1/8" ports suit compact wet-area panels.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X225S the Right Cylinder?
At 245.3 N push (0.5 MPa) the 25 mm bore sits between the 20 mm MG at 157 N and the 32 mm MG at 402.2 N - pick down if your load is under about 90 N working force, up if you need over 250 N or want margin at 0.5 MPa supply. The 225 mm stroke is well inside the 500 mm standard range for this bore, so it ships as a catalogue item. On a stroke this long, keep the rod load pure axial; side loads bend the 10 mm rod and wear the seals early. Mount with LB foot, FA flange or CB clevis brackets (SDB pivot pairs with CB), and use I or Y rod knuckles to absorb small misalignment. The fitted magnet means CMSG / DMSG / EMSG switches work out of the box.

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 MG Stainless Steel Mini Air Cylinder MG25X225S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum is 50 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, and the port is 1/8" on every MG bore.
Yes - the S in the model code means a magnet is built into the piston, so CMSG, DMSG or EMSG reed/electronic switches mount directly on the barrel for end-of-stroke detection. The fixed anti-impact pads at each stroke end only decelerate the piston to soften impact; they are not an adjustable air cushion (that is the MGC series) and they do not lock or hold a load when air is removed.
