About the Airtac MG Stainless Steel Mini Air Cylinder MG25X200
With a 25 mm bore and 200 mm stroke, this double acting JIS round-body mini cylinder pushes with about 245 N at 0.5 MPa and 343 N at 0.7 MPa, enough for compact clamping, sorting and eject tasks on lean automation cells. The riveted body pairs a SUS304 stainless barrel with a hard-chrome plated rod, so it shrugs off washdown mist and damp shop air that swells painted-steel minis.
Because the footprint follows the JIS mini-cylinder standard, standard brackets and I or Y rod knuckles bolt straight on when you standardise spares. At 0.5 MPa the push force equals roughly 25 kg of thrust, so plan on lifting about 12 kg vertically once you keep a 2:1 margin. Stroke ends carry fixed anti-impact bumper pads that soften direction change; they decelerate only and are not an adjustable air cushion.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X200 Is Used
Bottle line reject pusher
The 245 N push at 0.5 MPa kicks misfilled bottles off a 300 mm wide conveyor lane at up to 800 mm/s, with the bumper pad absorbing the return stop.
Carton flap tucker
A 200 mm stroke reaches across small carton flaps on a packaging table, folding them before taping; the stainless barrel tolerates humid glue-room air.
Lab sample elevator
Lifts about 12 kg sample racks vertically in a test rig with a 2:1 margin, using an FA flange mount and a guided rod knuckle.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X200 the Right Cylinder?
Size between neighbours: the 20 mm bore delivers about 157 N push at 0.5 MPa, while stepping up to 32 mm raises it to about 402 N - pick the 25 mm when your load sits between those figures. The 200 mm stroke is well inside the 500 mm standard range, but keep the rod side-loaded lightly; a 10 mm rod over 200 mm of travel will bend if a guide is missing. Mount with LB foot, FA flange, CB clevis or SDB pivot. This SKU carries no magnet, so position sensing with CMSG, DMSG or EMSG switches is not possible - order the S code if you need reed or Hall feedback. Note that with no rod lock or check valve, the load drifts if air pressure drops.
Quick checklist

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA / CB / SDB) & knuckle
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 MG25X200 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 spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-800 mm/s.
Not as supplied. This SKU has no magnet, so CMSG, DMSG or EMSG switches cannot detect it. Order the magnet version (S code in the model number) to enable those sensors. Also note the fixed bumper pads only soften the stroke end - they do not hold a load when air is lost.
