About the Airtac MG Stainless Steel Mini Air Cylinder MG32X125
With a 32 mm bore pushing 402.2 N at 0.5 MPa, the MG32X125 is a double acting JIS round-body mini cylinder that moves mid-weight fixtures, gates and small slides on compressed air. The 125 mm stroke is covered by fixed anti-impact bumper pads at both ends, which soften the direction change without adding the plumbing of an adjustable cushion. Air runs at 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), and rod speed spans 30-800 mm/s.
The barrel is SUS304 stainless steel riveted onto the covers, paired with a hard-chrome plated 12 mm rod, so the body shrugs off washdown and damp shop air far better than painted mini cylinders. Because the footprint follows the JIS mini-cylinder standard, standard JIS brackets and I/Y rod knuckles bolt straight on. For sizing, treat roughly 240 N (about 24 kg lifted vertically with a 2:1 margin) as the practical working force at 0.5 MPa. Note that this SKU carries no magnet, so CMSG / DMSG / EMSG switches cannot be fitted unless you order the S code.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X125 Is Used
Packaging line pusher
A 402.2 N push at 0.5 MPa parts cartons or deflects packs on a conveyor, and the bumper pad quiets the stroke ends at cycle rates up to 800 mm/s.
Small press and forming fixture
The 32 mm bore gives about 563 N at 0.7 MPa for light staking, marking and forming jigs where a 125 mm approach stroke clears the part.
Battery-changer gate on warehouse chargers
Stainless SUS304 barrel and chrome rod stand up to the humid, occasionally washed floor around forklift charging bays while the clevis mount absorbs gate misalignment.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X125 the Right Cylinder?
At 32 mm bore you sit mid-range in the MG family: the 25 mm bore delivers 245.3 N push at 0.5 MPa and suits lighter clamps, while the 40 mm bore reaches 628.3 N for heavier tooling. Pick the MG32X125 when your load needs roughly 240-400 N of working push on a 125 mm stroke. Remember that a plain MG drifts when air is removed or the valve centres, so add an external rod lock or pilot check valve if the load must stay put. Mount it with LB foot, FA flange, CB clevis or SDB pivot brackets, and order the S magnet code if you plan position sensing. On a 125 mm stroke keep side loads off the 12 mm rod to avoid premature seal wear.
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 MG32X125 FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa push rises to 563 N and pull to 483.8 N. The theoretical maximum 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 ordered: this SKU has no built-in magnet, so CMSG, DMSG or EMSG switches cannot detect the piston. Order the magnet version (S code in the model number) if sensing is needed. The cylinder itself is a JIS round-body stainless mini cylinder with a fixed bumper pad, a 1/8" port and PT threads.
