About the Airtac MG Stainless Steel Mini Air Cylinder MG32X250
With a 32 mm bore and a 250 mm stroke, this MG cylinder delivers about 402.2 N of push force at 0.5 MPa and 563 N at 0.7 MPa, making it a solid double acting choice for mid-size pick, clamp and eject jobs on compact machinery. The round barrel is rolled onto the covers in SUS304 stainless, so the body shrugs off damp air, light washdown and outdoor exposure far better than painted-steel minis.
Because the MG follows the JIS mini-cylinder standard, its mounting holes and accessory footprint accept standard JIS brackets and rod knuckles, which keeps spares interchangeable across your machine park. In practice, plan on roughly 240 N of usable work force at 0.5 MPa, which is about 24 kg lifted vertically with a 2:1 margin. The fixed anti-impact bumper pads soften the direction change at each stroke end; they decelerate only and are not an adjustable cushion.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X250 Is Used
Bottling line ejector
The 402.2 N push at 0.5 MPa rejects filled bottles or cartons off a conveyor lane at up to 800 mm/s, and the SUS304 barrel copes with routine washdown around the filler.
Press-fit stamping assist
About 563 N at 0.7 MPa is enough to seat small bushings or labels in a light bench press fixture, with the bumper pad easing the ram at the bottom of the 250 mm stroke.
Case clamp on a carton sealer
Holds flaps square while tape or glue sets; the clevis mount lets the rod follow slight case misalignment without side-loading the 12 mm rod.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X250 the Right Cylinder?
Size check: the 25 mm bore MG pushes about 245.3 N at 0.5 MPa, so step up to this 32 mm unit when your load or speed needs more than roughly 240 N of working force; if 402.2 N is still marginal, the 40 mm bore gives 628.3 N. Remember that a plain MG drifts when air is lost or the valve centres, so add an external rod lock or a pilot check valve if the load must stay put. This SKU has no magnet, so CMSG, DMSG or EMSG switches cannot be fitted; order the S code if you need position sensing. With 250 mm of travel, keep side loads off the 12 mm hard-chrome rod and guide the part externally to avoid rod bending. Mount it with LB foot, FA flange, CB clevis or SDB pivot hardware.

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 MG32X250 FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum is 82 kgf at 1.0 MPa. Operating range 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".
Not as supplied. This SKU has no built-in magnet, so CMSG, DMSG or EMSG switches cannot detect the piston. Order the magnet version (the S code, e.g. MG32X250S) if you need end-of-stroke or mid-stroke sensing.
