About the Airtac MG Stainless Steel Mini Air Cylinder MG32X25
With a 32 mm bore and a short 25 mm throw, this MG delivers about 402.2 N of push and 345.6 N of pull at 0.5 MPa, and it is double acting, so air drives the rod out and back. The riveted round body pairs a SUS304 stainless barrel with a hard-chrome plated rod, an edge over painted-steel minis in damp or washdown corners, and a fixed anti-impact bumper pad softens each direction change at the stroke end.
Because the MG follows the JIS mini-cylinder standard, its mounting and accessory footprint drops straight onto standard JIS brackets and rod knuckles, which keeps spares simple. Plan on roughly 240 N of usable work at 0.5 MPa, or a vertical lift of about 20 kg with a 2:1 margin. Note that the rod drifts if air is lost, so hold the load with an external check valve or rod lock.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X25 Is Used
Clamp fixture on a CNC jig
A 25 mm clamp stroke with about 402 N of push at 0.5 MPa holds aluminium parts firmly in a milling fixture, and the stainless barrel shrugs off coolant mist.
Carton kick-off on a packing line
The short throw ejects small cartons between conveyor lanes at up to 800 mm/s, with the bumper pad damping each reversal to cut noise.
Sample pusher in a lab autoloader
A 20 kg-class vertical push margin and a corrosion-resistant SUS304 body suit tray-advance moves in analytical equipment that sees frequent cleaning.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X25 the Right Cylinder?
At 402.2 N push (0.5 MPa) this 32 mm bore sits between the 25 mm MG (245.3 N) and the 40 mm MG (628.3 N); pick 32 when the 25 is marginal but the 40 is oversized. The 25 mm stroke suits short clamp or eject moves; for longer runs remember side loads bend the 12 mm rod, so guide the workpiece. Mount with LB foot, FA flange, CB clevis or SDB pivot, and add the S magnet code if you will need CMSG / DMSG / EMSG switches later - this SKU has no magnet, so no sensor can be fitted as supplied.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 MG32X25 FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa that rises to 563 N push and 483.8 N pull. Theoretical maximum force is 82 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed runs 30-800 mm/s.
Not as supplied - this SKU has no built-in magnet, so CMSG, DMSG or EMSG switches cannot detect it. Order the magnet version (S code in the model, e.g. MG32X25S) if sensing is needed. The 1/8" port takes PT thread as standard, with G or NPT options.
