Airtac MI16-20 Stainless Steel Mini Cylinder MI16X80SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X80SR is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 80mm 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 MI16X80SR
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles an 80 mm stroke with a 16 mm bore. The riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its 1/8" port and M6x1.0 male rod thread keep the pneumatic plumbing compact.
Because the piston carries a magnet, this -S variant directly supports CMSG, DMSG and EMSG reed or electronic switches for end-of-stroke confirmation. The fixed TPU bumper pads absorb impact at the stroke extremes without offering adjustable cushioning. For practical sizing, plan for roughly 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 MI16X80SR Is Used
PCB Routing Gate
Actuates a lightweight diverter flap on an electronics assembly line, using the 80 mm stroke to route printed circuit boards into testing stations.
Carton Flap Folder
Folds small corrugated box flaps prior to taping, where the 100.5 N thrust easily overcomes board resistance without crushing the carton.
Lab Sample Ejector
Pushes prepared specimen trays out of a chemical analyser, relying on the stainless build to withstand occasional reagent splashes.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X80SR the Right Cylinder?
When sizing this 16 mm bore, stepping down to the Ø12 version 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 80 mm stroke is well within the 500 mm maximum for this bore, but you should still guard against side loads to prevent rod bending. The R back cover supplies an axial-in port orientation for tidy routing.
This SKU includes the -S magnet for position sensing, but a plain MI cylinder will drift if air pressure drops or the valve is centred—the fixed bumpers only decelerate the end of stroke and act as neither a lock nor a brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve. You can mount the body using standard ISO 6432 brackets, alongside LB foot, FA flange, SDB pivot or TC trunnion hardware.
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 MI16X80SR FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. 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. The air port size is 1/8".
Yes to sensors, no to adjustable cushions. The -S suffix means it has a built-in magnet for CMSG, DMSG and EMSG switches. However, it only has fixed TPU bumper pads for end-of-stroke deceleration; you would need the MIC variant for adjustable air cushioning.
