About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 125 mm stroke with a CM round rear cover. The riveted stainless barrel and Ø8 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its 1/8" port feeds the chamber efficiently, while fixed TPU pads absorb end-of-stroke impacts.
Because it conforms to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing. For real work at 0.5 MPa, plan for roughly 94 N of usable load, which translates to lifting about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125SCM Is Used
Package Diverter
Pushes light cardboard cartons on a packaging line using 157 N of thrust, with the stainless build resisting humid warehouse environments.
Textile Loom Guide
Cycles rapidly at 30-800 mm/s to shift a yarn guide, relying on the 125 mm stroke and fixed TPU pads to soften directional changes.
Lab Sample Ejector
Ejects processed vials from a testing carousel, lifting roughly 8 kg of fixture weight vertically thanks to the double-acting 0.5 MPa chamber pressure.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125SCM the Right Cylinder?
This Ø20 bore sits neatly between the Ø16 (100.5 N push @0.5 MPa) and Ø25 (245.3 N push @0.5 MPa) models, letting you step up or down in force as your application demands. The 125 mm stroke is well within the 500 mm maximum, keeping the assembly compact. To mount it, utilize the CM round back cover alongside standard LB foot, FA flange, or TC trunnion hardware.
Remember that venting the air or centering the valve causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the rod. For suspended loads that must hold position, add an external rod lock or a pilot-operated check valve. At 125 mm of extension, ensure your front mounting resists side loads to prevent rod bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
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 Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125SCM FAQ
This Ø20 mm bore cylinder uses a 1/8" air port. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The CM designation specifies a round rear cover, and the body uses standard ISO 6432 mounting dimensions for easy bracket integration.
