Airtac MG Stainless Steel Mini Air Cylinder MG20X75
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG20X75 is a genuine double acting JIS-standard round-body mini air cylinder with a Ø20mm bore and 75mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MG Stainless Steel Mini Air Cylinder MG20X75
With a 20 mm bore and 75 mm stroke, this MG delivers about 157 N push and 131.9 N pull at 0.5 MPa (219.8 N / 184.7 N at 0.7 MPa), all in a compact double acting round body built to the JIS mini-cylinder standard. The SUS304 stainless barrel and hard-chrome plated 8 mm rod shrug off damp, washdown-prone spots that quickly ruin painted-steel minis, and the riveted covers keep the package short and light.
Because the footprint follows JIS, the MG20X75 drops onto standard JIS mini-cylinder brackets and I or Y rod knuckles, so spares and fixtures carry over. The fixed anti-impact bumper pad at each stroke end softens direction change; it decelerates only and is not an adjustable cushion. A practical sizing note: plan on roughly 94 N of real work at 0.5 MPa, which lifts about 4 kg vertically with a 2:1 margin. If the load must stay put when air is lost, add an external rod lock or pilot check valve, since the piston will drift.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG20X75 Is Used
Lab sample pusher
Slides sample trays of a few kilograms between test stations, where the 94 N usable push at 0.5 MPa and stainless barrel suit frequent cleaning.
Small carton kick-off
Kicks light cartons off a conveyor lane; the 75 mm stroke clears a standard lane and the bumper pad quiets each direction change.
Fixture clamp on assembly bench
Clamps small brackets during manual assembly, using about 219.8 N push at 0.7 MPa for repeatable holding force.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG20X75 the Right Cylinder?
At 157 N push (0.5 MPa) this is the smallest MG bore; step up to MG25 for about 245 N or down is not possible within the series. If you need adjustable end-of-stroke cushioning for higher speeds or heavier loads, the MGC variant in larger bores is the path. Mounting choices: LB foot, FA flange, CB clevis, SDB pivot (with CB). This SKU carries no magnet, so CMSG / DMSG / EMSG switches cannot be fitted - order the S code if sensing is needed. At 75 mm stroke side loads stay modest, but keep the rod square to the load to protect the 8 mm rod and M8x1.25 male thread.
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 MG20X75 FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa, 219.8 N push and 184.7 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed runs 30-800 mm/s.
Not on this SKU. It has no built-in magnet, and the CMSG / DMSG / EMSG switches only work with the magnet option, which is ordered as the S code (for example MG20X75S). The stainless JIS round body itself is otherwise identical, with a 1/8" port and PT thread.
