About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CMTC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 25 mm strokes with efficiency. The riveted barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp production areas. Its 1/8" port feeds the bore efficiently, while fixed TPU bumper pads absorb the end-of-stroke impact. Because it lacks the -S suffix, this specific SKU cannot accept CMSG, DMSG or EMSG magnetic switches.
For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it can comfortably lift an 8 kg part vertically with a 2:1 safety margin. The CM round rear cover pairs neatly with the included TC trunnion bracket for pivot-mounted actuation. Operating between 0.15 and 1.0 MPa, the unit travels at 30-800 mm/s.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CMTC Is Used
Clamp Actuation
Drives short-stroke clamping jaws on small machining fixtures, utilising the 157 N push force to secure light aluminium workpieces.
Package Deflector
Pivots a routing gate via its TC trunnion to divert small cartons on a packaging line, benefiting from the compact 25 mm stroke.
Parts Ejector
Pushes finished moulded plastic parts out of a die zone, where the stainless build withstands humid ambient conditions.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CMTC the Right Cylinder?
When sizing this 20 mm bore, stepping down to the Ø16 version drops the 0.5 MPa push force to 100.5 N, whereas moving up to the Ø25 bore raises it to 245.3 N. The TC trunnion mount supplied with this CM back-cover model suits pivoting linkages, but remember that a standard cylinder drifts if air pressure drops or the valve is centred. To prevent a suspended load from creeping, fit an external rod lock or a pilot-operated check valve rather than relying on the bumper pads. The short 25 mm stroke keeps rod bending stress minimal even under lateral loads.
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 MI20X25CMTC FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. 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.
No, because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It uses the ISO 6432 mounting interface for standard brackets and relies on fixed TPU bumpers, not adjustable cushions.
