About the Airtac MGC Stainless Steel Mini Cylinder MGC20X225
The AirTAC MGC20X225 is a double acting, JIS-standard round-body mini cylinder with a 20 mm bore and 225 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike a fixed bumper pad, the cushion needle is adjustable, so you can dial in smooth deceleration near end of travel. That makes this cushioned mini a strong choice for higher piston speeds and heavier moving loads than the bumper-type MG can absorb without hammering the covers. At 0.5 MPa it delivers 157 N push and 131.9 N pull, rising to 219.8 N push at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Construction follows the MG family recipe: a SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated (20 um) carbon-steel rod and a two-way piston seal that also stores lubricant. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates -20 to +70 C, and cycles at 30-800 mm/s. The 8 mm rod carries an M8x1.25 male thread and the port is M5x0.8. Mounting is via FA flange or LB foot, with I and Y rod knuckles available. This SKU has no magnet, so no sensor can be fitted; order the -S code to enable CMSG / DMSG / EMSG switches.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC20X225 Is Used
Small parts ejection
The adjustable air cushion lets the 20 mm bore run at higher speeds to eject light components from fixtures without the piston slamming the covers at end of stroke.
Conveyor diverting
With 157 N push at 0.5 MPa, this cylinder can nudge or divert small packages on light conveyor lines, while the variable cushion smooths the stop at both ends.
Clamping and positioning
Compact JIS round-body footprint with FA flange or LB foot mounting suits light clamping and indexing moves on compact automation, with -S sensors for position feedback.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC20X225 the Right Cylinder?
At 20 mm bore this is the smallest MGC available, so size up if you need more force: the 25 mm bore pushes 245.3 N at 0.5 MPa and the 32 mm bore reaches 402.2 N. If you do not need cushioning, the bumper-type MG covers the same 20-40 mm bores without the adjustable deceleration. For this cylinder, plan around 157 N push at 0.5 MPa; as a rule of thumb, use about 0.6 of that force for a safe working load, roughly 9.6 kgf, and halve it again for vertical lifting, giving about 4.8 kg. The 225 mm stroke sits well inside the 500 mm maximum standard stroke for this bore, and strokes up to 800 mm are made to order. On long strokes like this, watch side loading on the 8 mm rod and consider external guidance. Choose LB foot or FA flange mounting, PT thread as standard (G or NPT on request), and add the -S magnet if you need CMSG / DMSG / EMSG position sensing.

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 and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGC Stainless Steel Mini Cylinder MGC20X225 FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa those figures rise to 219.8 N push and 184.7 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. For safe sizing, treat about 0.6 of the 0.5 MPa push force, roughly 9.6 kgf, as the usable working load.
The cushion needle at each stroke end is adjustable, so you can tune the deceleration to match speed and moving mass; it is an air cushion, not a fixed bumper pad. It only slows the piston near end of travel and is not a lock or brake. If the load must be held against air loss, add an external rod lock or pilot check valve.
