Airtac MI16-20 Stainless Steel Mini Cylinder MI16X170SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X170SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 170mm 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 MI16X170SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The Ø16 mm bore uses a 1/8" port and a Ø6 mm piston rod, while the 170 mm stroke falls well within the 500 mm standard limit. Its riveted round-body construction shrinks the footprint compared to bulkier alternatives, and the fixed TPU bumper pads quietly absorb end-of-stroke impacts.
Because the stainless barrel and rod resist mild corrosion, the unit survives washdown and damp environments better than painted alternatives. The built-in magnet supports CMSG, DMSG, and EMSG switches for position detection. For practical sizing, plan for about 60 N of actual work at 0.5 MPa, which translates to safely lifting a 5.1 kg load vertically with a 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X170SU Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, utilizing the 170 mm stroke to redirect small cartons at 100.5 N of push force.
Lab Sample Ejection
Pushes prepared test tubes out of a centrifuge carousel, where the stainless build resists humidity and the CMSG sensor confirms ejection.
Small Parts Clamp
Secures plastic housings during a ultrasonic welding cycle, applying 86.4 N of pull at 0.5 MPa to hold the part firmly against the fixture.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X170SU the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 MI generates 56.5 N of push at 0.5 MPa, whereas stepping up to the Ø20 MI yields 157.0 N. The 170 mm stroke provides ample travel, but keep side-loads minimized to prevent rod bending over that distance. The U-style back cover provides a 90-degree port orientation for tight routing.
Remember that venting the air supply causes the piston to drift, as the fixed bumpers only decelerate the stroke end rather than locking the rod. To suspend a load safely during an air loss event, install an external pilot-operated check valve or a dedicated rod lock.
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 MI16X170SU FAQ
The 16 mm bore generates 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa. It uses a 1/8" air port and a Ø6 mm rod with an M6x1.0 male thread.
No, the base MI uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion (which requires the MIC variant). However, the Ø16 bore does conform to ISO 6432 mounting dimensions, allowing it to drop into standard mini-cylinder brackets and clevises.
