About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 250 mm stroke with a 1/8 inch air port. The riveted stainless barrel and Ø8 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp washdown zones. Built-in fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because it conforms to ISO 6432 mounting dimensions, this Ø20 unit drops directly into standard mini-cylinder brackets and clevises. The -S suffix means a piston magnet is inside, ready for CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SU Is Used
Diverter Gate Actuation
Pushes sorting flaps on packaging lines using its 157 N thrust, while the stainless build withstands humid packing environments.
Light Press Assembly
Provides the downward push for seating small electronic connectors, safely applying about 94 N of working force at 0.5 MPa.
Lab Sample Handling
Extends 250 mm to move test racks between stations, relying on the U rear cover for a compact 90-degree pivot mount.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SU the Right Cylinder?
When sizing this 250 mm stroke model, compare it against its neighbours: the Ø16 bore yields 100.5 N of push at 0.5 MPa, while the Ø25 steps up to 245.3 N. If your machine requires a held load during air loss or valve centering, remember this cylinder will drift; the TPU bumpers only decelerate the end of stroke and act as neither a lock nor a brake. You must add an external rod lock or pilot-operated check valve for secure holding. The U suffix specifies a 90-degree rear cover for compact pivot mounting.
A 250 mm stroke demands attention to side loading. Keep the load guided to prevent rod bending over that long extension. The 1/8 inch port and M8x1.25 male rod thread are fixed by the Ø20 bore. If you need adjustable air cushioning for high-speed cycles rather than fixed bumpers, look at the MIC variant instead.
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 MI20X250SU FAQ
This Ø20 mm cylinder uses a 1/8 inch 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 force of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in magnet for CMSG, DMSG or EMSG switches. The U suffix denotes a 90-degree rear cover, and the body conforms to ISO 6432 mounting dimensions for standard brackets.
