Airtac MI16-20 Stainless Steel Mini Cylinder MI16X175SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X175SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 175mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X175SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 175 mm stroke with ease. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp production areas. Because it uses the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises.
The integrated piston magnet (-S) supports CMSG, DMSG and EMSG position switches for end-of-stroke confirmation. Fixed TPU bumper pads absorb the impact at stroke extremes without the tuning hassle of an adjustable cushion. For real-world sizing, plan for about 60 N of actual work at 0.5 MPa, which translates to safely lifting a 5.1 kg part vertically with a 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X175SU Is Used
Package Diverting
Pushes lightweight cardboard cartons on a packaging line using the 100.5 N extend force, with the 175 mm stroke clearing guide rails.
Textile Loom Tensioning
Maintains thread tension in humid environments where the stainless steel barrel resists washdown and mild corrosion better than standard steel.
Small Part Ejection
Ejects plastic moulded parts from a press, relying on the CMSG sensor magnet to confirm the ejection stroke completed before the mould closes.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X175SU the Right Cylinder?
When sizing this 16 mm bore, stepping down to the Ø12 variant drops the 0.5 MPa push force to 56.5 N, while moving up to the Ø20 bore increases it to 157.0 N. The 175 mm stroke is well within the 500 mm maximum for this bore, though at this extension you should watch for side-loading and rod-bending forces to prevent premature seal wear. The U-type back cover provides a 90-degree port orientation for tight routing.
Note that a standard double-acting cylinder drifts if air pressure is lost or the valve is centred; the TPU bumpers only decelerate the end of stroke and do not function as a lock. To suspend a load safely, install an external rod lock or a pilot-operated check valve in the air line.
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 MI16X175SU FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port is 1/8 inch.
No, it uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. It also does not hold position on air loss; you need an external rod lock or pilot check valve for that.
