About the Airtac MG Stainless Steel Mini Air Cylinder MG32X25S
With a 32 mm bore and a short 25 mm stroke, this MG delivers about 402.2 N of push and 345.6 N of pull at 0.5 MPa (563 N push at 0.7 MPa) in a double acting single-rod format that follows the JIS mini-cylinder standard. The round SUS304 stainless barrel is riveted onto the covers with a hard-chrome plated 12 mm rod, so the body shrugs off damp washdown and outdoor conditions that quickly ruin painted-steel minis, and its mounting footprint drops straight onto standard JIS brackets and rod knuckles.
At the stroke ends, fixed anti-impact bumper pads soften the direction change - they decelerate the piston, they are not an adjustable air cushion. Because the magnet is built in (the S code), CMSG, DMSG or EMSG switches can be clipped on for end-position sensing without modification. For sizing, plan on roughly 241 N of usable push at 0.5 MPa, which means this cylinder lifts about 20 kg vertically with a 2:1 margin; running air is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X25S Is Used
Small parts clamping on CNC fixtures
The 402.2 N push at 0.5 MPa holds aluminium or plastic workpieces in drilling and milling jigs, and the 25 mm stroke suits quick clamp-and-release cycles.
Position-verified ejector on packaging lines
With the built-in magnet and a CMSG switch, the machine PLC confirms the 25 mm kick-out stroke completed before the next carton advances.
Sample press in lab automation
The stainless SUS304 barrel tolerates wipe-down in analytical and diagnostic equipment where a short, controlled 241 N-class press is needed.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X25S the Right Cylinder?
The 32 mm bore sits in the middle of the MG range: step down to a 25 mm bore if 245.3 N push at 0.5 MPa is enough, or step up to a 40 mm bore (628.3 N push at 0.5 MPa) for heavier clamping. With only 25 mm of stroke, keep the rod side-load free - short strokes amplify bending if the load is cantilevered, so guide it externally. Mount with LB foot, FA flange, CB clevis or SDB pivot brackets, and add I or Y rod knuckles where the load pivots. Note that a plain MG drifts when air is lost or the valve centres; for a held position, fit an external rod lock or pilot check valve. The built-in magnet means CMSG / DMSG / EMSG switches work out of the box.

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 MG32X25S 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 pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), speed 30-800 mm/s, and a 1/8" port on every MG bore.
The SUS304 round barrel and hard-chrome plated 12 mm rod resist corrosion in damp, food or outdoor spots, the JIS-standard mounting interface swaps onto existing mini-cylinder brackets, and the fitted magnet accepts CMSG / DMSG / EMSG switches. The fixed bumper pad softens stroke-end impact but does not lock or hold a load.
