About the Airtac MG Stainless Steel Mini Air Cylinder MG25X175
With air working both ways, the MG25X175 is a double acting JIS round-body mini cylinder: a 25 mm bore drives a 10 mm hard-chrome-plated rod through a 175 mm stroke, with the SUS304 stainless barrel and covers riveted into one compact sealed body. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N, rising to 343.4 N on the extend stroke at 0.7 MPa, with a theoretical ceiling of 50 kgf. In practice, budget roughly 147 N of that 0.5 MPa push for real work, which is about 15 kg of usable horizontal load.
The fixed anti-impact pad in the front cover decelerates the rod at each end of travel, softening direction changes on fast cycles without any adjustment to make. Because the barrel is stainless rather than painted steel, this bore shrugs off damp workshops, washdown-adjacent lines and outdoor fixtures, and its JIS mounting footprint accepts standard mini-cylinder brackets and rod knuckles. Note that when air is removed the piston drifts freely, so an external rod lock or pilot check valve is needed for a held load.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X175 Is Used
Packaging line push-off
Ejecting cartons or trays sideways off a conveyor at the end of a filling or wrapping line, where the 245.3 N push at 0.5 MPa clears typical retail packs quickly and the bumper pad absorbs the stop.
Small-part clamping fixture
Holding aluminium or plastic housings in a drilling or assembly jig, using roughly 147 N of usable clamp force from the 25 mm bore without oversizing the machine envelope.
Sorting gate actuator
Kicking items into a reject chute or lane divider on a sorting conveyor, where the 175 mm stroke covers the gate travel and the stainless barrel tolerates humid or dusty plant air.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X175 the Right Cylinder?
Size by force first: the smaller MG20X175 delivers 157.0 N push at 0.5 MPa, while stepping up to the MG32X175 buys 402.2 N. If your load sits between those, the 25 mm bore at 245.3 N is the efficient middle choice, and the 175 mm stroke stays well inside the 500 mm standard range for this bore. For vertical lifting, halve the theoretical 25 kg lift equivalent and plan on about 12 kg with margin. Mounting options are LB foot, FA flange, CB clevis or SDB pivot, with I and Y knuckles on the M10x1.25 rod thread. This SKU has no magnet, so CMSG, DMSG or EMSG switches cannot be fitted; order the S code if you need position sensing. On a 175 mm stroke, keep side loads low to protect the 10 mm rod from bending.

- ✓ 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 MG25X175 FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa those figures rise to 343.4 N and 288.5 N. The theoretical maximum is 50 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), and rod speed runs from 30 to 800 mm/s.
Not as supplied. This SKU has no magnet, so CMSG, DMSG or EMSG reed or electronic switches cannot detect the piston. Order the magnet version (the S code, e.g. MG25X175S) if you need end-of-stroke or mid-stroke signalling.
