Airtac MG Stainless Steel Mini Air Cylinder MG25X200S
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG25X200S is a genuine double acting JIS-standard round-body mini air cylinder with a Ø25mm bore and 200mm 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 MG25X200S
With a 25 mm bore and 200 mm stroke, this MG delivers about 245.3 N of push at 0.5 MPa (343.4 N at 0.7 MPa) and works double acting, so air drives the rod out and pulls it back. The riveted round body pairs a SUS304 stainless barrel with a hard-chrome plated rod, an edge over painted-steel minis in damp, washed-down or outdoor spots. Because the MG follows the JIS mini-cylinder standard, its footprint drops onto standard JIS brackets and rod knuckles, which simplifies spares and redesigns.
The fixed anti-impact pad at each stroke end softens the direction change - it decelerates, it is not an adjustable air cushion. The fitted magnet lets CMSG, DMSG or EMSG switches report end positions without any extra option. As a sizing guide, plan on roughly 147 N of real work at 0.5 MPa, and for vertical lifts count on about 7 kg with a 2:1 margin - enough for small grippers, chutes and light fixture plates.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X200S Is Used
Carton push-off on packing lines
The 245.3 N push at 0.5 MPa slides small cartons off a conveyor stop, and the magnet-fed CMSG switch confirms full extension before the next box indexes.
Sample tray indexing in lab automation
A 200 mm stroke moves sample trays between stations, while the SUS304 barrel shrugs off repeated wipe-downs with mild cleaning agents.
Light part press-fit in fixture building
About 147 N of usable force at 0.5 MPa seats bushings and labels in jigs; the fixed bumper pad keeps the return stroke quiet at cycle end.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X200S the Right Cylinder?
At 25 mm bore you sit mid-range: the 20 mm MG gives about 157 N push at 0.5 MPa, while stepping up to 32 mm raises it to about 402 N. Pick the 32 mm if your load or friction eats more than half of the 245 N rating. The 200 mm stroke is well inside the 500 mm standard range for this bore. Note that a plain MG drifts when air is lost - the bumpers only soften the stroke end - so add an external rod lock or a pilot check valve if the load must stay put. This SKU already carries the magnet, so CMSG / DMSG / EMSG switches mount directly; choose LB foot, FA flange, CB clevis or SDB pivot mounting to suit the machine. At 200 mm of stroke, keep side loads off the 10 mm rod or guide the load externally to avoid rod bending.

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 MG25X200S 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".
Yes - the S in MG25X200S means a magnet is built into the piston, so AirTAC CMSG, DMSG or EMSG reed/electronic switches clip onto the 25 mm barrel to signal end positions. The bumper pads only soften the stroke-end impact; they do not hold the load if air pressure drops.
