Airtac MI16-20 Stainless Steel Mini Cylinder MI16X240SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X240SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 240mm 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 MI16X240SU
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles a 240 mm stroke with a 1/8" port. The Ø6 mm piston rod and M6x1.0 male thread drive reliably at 30-800 mm/s. Its riveted round body shrinks the footprint compared to bulkier alternatives, while the stainless barrel and rod resist mild corrosion in damp or washdown settings.
Because the 0.5 MPa thrust translates to about 5.1 kgf, you can plan to lift roughly 2.5 kg vertically with a safe 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing. Fixed TPU bumper pads absorb the impact at stroke extremes, and the U-type back cover provides a 90-degree port orientation for tight machinery layouts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X240SU Is Used
Package Diverter Arm
Pushes lightweight cardboard cartons on a packaging line using the 100.5 N thrust, while the stainless body handles occasional moisture washdowns.
Textile Loom Guide
Shifts a yarn guide back and forth across the 240 mm stroke, relying on the U-type 90-degree back cover to keep pneumatic hoses neatly routed.
Bin Lid Actuator
Opens and closes small sorting bin lids, lifting roughly 2.5 kg safely with a 2:1 margin while the CMSG sensor confirms the fully open position.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X240SU the Right Cylinder?
When sizing this 16 mm bore, stepping down to the Ø12 bore drops the 0.5 MPa push force to 56.5 N, whereas stepping up to the Ø20 bore raises it to 157.0 N. The 240 mm stroke is well within the 500 mm maximum for this bore, but at this length you should watch for side loads to prevent rod bending. Its ISO 6432 mounting dimensions allow easy integration into standard mini-cylinder brackets and clevises.
Note that venting or losing air pressure will cause the piston to drift, as the TPU bumpers only decelerate the end of travel and do not act as a brake. To suspend a load securely, add an external rod lock or a pilot-operated check valve to your circuit.
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 MI16X240SU FAQ
This 16 mm bore cylinder uses a 1/8" port. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum force of 20.5 kgf at 1.0 MPa.
Yes, the -S suffix means it has a piston magnet for CMSG, DMSG and EMSG switches. It uses fixed TPU bumper pads to decelerate at the stroke end, not an adjustable air cushion; for adjustable cushioning consider the MIC variant.
