About the Airtac MG Stainless Steel Mini Air Cylinder MG20X175
With a 20 mm bore and a 175 mm stroke, this MG delivers double acting push and pull on filtered air, reaching 157 N extend force and 131.9 N retract force at 0.5 MPa (219.8 N and 184.7 N at 0.7 MPa). The round barrel is rolled from SUS304 stainless steel onto the covers, so the body stays compact and corrosion-resistant, while the hard-chrome plated 8 mm rod shrugs off damp or washdown conditions better than a painted mini cylinder.
Because the MG follows the JIS mini-cylinder standard, its mounting footprint and rod knuckles interchange with standard JIS brackets, which simplifies spares and retrofit design. A fixed anti-impact pad at the front cover softens the stroke-end shock; it only decelerates, so plan an external rod lock or pilot check valve wherever the load must stay put if air pressure drops. At 0.5 MPa the push force equates to roughly 16 kgf, so for real work budget around 94 N, which lifts about 9 kg vertically with a 2:1 margin.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG20X175 Is Used
Small-part ejection on assembly benches
The 157 N push at 0.5 MPa is enough to eject pressed-in bushings or push light components off a fixture, and the 175 mm stroke clears a deep nest in one move.
Pusher on a bottling-line conveyor
Stainless SUS304 barrel and hard-chrome rod handle humid, wash-prone conveyor zones, while the bumper pad softens each divert stroke at up to 800 mm/s.
Lid press on a lab sample station
About 94 N of usable work force presses snap-on sample lids without crushing, and the JIS mounting lets the cylinder drop into standard mini-cylinder brackets.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG20X175 the Right Cylinder?
At 157 N push (0.5 MPa) this 20 mm bore suits light clamping, sorting and small part transfer; step down is not possible within the MG range, while the 25 mm bore gives 245.3 N push at the same pressure if you need more margin. The 175 mm stroke is a standard length (up to 500 mm is catalog for this bore), but keep rod side-loading low on longer travels to protect the 8 mm rod. This SKU has no magnet, so CMSG, DMSG or EMSG switches cannot be fitted; order the S code if position sensing is needed. Mount it with LB foot, FA flange, CB clevis or SDB pivot brackets, and pair rod couplings with I or Y knuckles.

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 MG20X175 FAQ
Push is 157 N and pull is 131.9 N at 0.5 MPa; at 0.7 MPa push rises to 219.8 N and pull to 184.7 N, with a theoretical maximum of 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-800 mm/s, and the fluid is air filtered to 40 um.
No. This SKU is supplied without the built-in magnet, and the CMSG, DMSG or EMSG switches only work on cylinders ordered with the S magnet code. If sensing is required, specify the magnet version instead. Also note the anti-impact pad only cushions the stroke end; it does not lock or hold a load when air is lost.
