Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 70mm 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 MI16X70SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 70 mm stroke with a 1/8 inch air port. The riveted barrel and Ø6 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because the piston pushes with roughly 100.5 N at 0.5 MPa, you can plan for about 60 N of actual work, which translates to lifting a 5.1 kg part vertically with a safe 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position detection, while the U back cover provides a 90-degree mounting orientation. Its dimensions also conform to the ISO 6432 mounting interface, dropping easily into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70SU Is Used
Diverter Gate Actuation
Pushes light routing flaps on packaging lines using its 100.5 N thrust, with the U cover allowing a tidy 90-degree mount alongside the belt frame.
Lab Sample Ejection
Ejects wet sample trays with a 70 mm stroke; the stainless construction resists chemical mist and routine washdown without corroding.
Small Part Seating
Seats lightweight plastic caps or electronic connectors, safely applying about 60 N of working force to avoid damaging delicate components.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70SU the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 option yields 56.5 N of push at 0.5 MPa, whereas stepping up to the Ø20 bore provides 157.0 N. If your valve centres or air supply drops, this cylinder will drift and cannot hold a suspended load—the TPU pads only decelerate the end of travel, so add an external rod lock or pilot check valve for secure holding. The 70 mm stroke is well within the 500 mm maximum, but still ensure your mounting guides prevent side-load rod bending. The included magnet pairs directly with reed or electronic sensors, and the U rear cover suits compact 90-degree pivot installations.
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 MI16X70SU FAQ
At 0.5 MPa it pushes with 100.5 N and pulls with 86.4 N. At 0.7 MPa the push is 140.7 N and pull is 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa, and the air port is 1/8 inch.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. However, it does not hold position on air loss; the piston drifts, and the fixed TPU bumper pads only decelerate the stroke end rather than locking the load.
