About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 250 mm stroke with ease. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. Its 1/8" port and M6x1.0 male rod thread provide robust pneumatic connections for compact machinery.
Featuring a built-in magnet for CMSG, DMSG or EMSG switches, the unit allows precise end-of-stroke detection. The fixed TPU bumper pads absorb impact at the stroke extremes without requiring manual adjustment. Plan for roughly 60 N of actual work at 0.5 MPa, which means it can safely lift about 5.1 kg vertically when applying a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SU Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, using the 100.5 N thrust to push small cartons onto secondary tracks.
Textile Loom Tensioner
Adjusts yarn tension bars in humid textile facilities, leveraging the stainless steel construction to withstand ambient moisture.
Bin Lid Automation
Pivots hinged access doors on storage bins via the 90-degree U rear cover, lifting roughly 5 kg lids smoothly through the 250 mm travel.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SU the Right Cylinder?
This 16 mm bore sits neatly between the lighter MI12 (56.5 N push) and the stronger MI20 (157 N push), giving you a clear upgrade path if your air pressure fluctuates. The U-type 90-degree rear cover simplifies side-mounting in tight spaces, while the ISO 6432 mounting dimensions ensure compatibility with standard mini-cylinder brackets and clevises.
Because it lacks an internal locking mechanism, the piston will drift if air supply is lost or the valve is centered; rely on an external pilot check valve to suspend loads safely. The 250 mm stroke is well within the 500 mm maximum, though side loads should be minimized to prevent rod bending over this travel distance. The included -S magnet enables direct sensor mounting.
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 MI16X250SU FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N. At 0.7 MPa it pushes 140.7 N and pulls 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port size is 1/8".
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. Use an external rod lock or pilot check valve for load holding.
