Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SR is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 20mm 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 MI16X20SR
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 20 mm strokes with precision. The riveted barrel and rod shrug off mild corrosion, making it far superior to painted alternatives in damp production areas. Its compact footprint drops directly into standard ISO 6432 mini-cylinder brackets and clevises, simplifying machine upgrades.
For practical sizing, plan for roughly 60 N of actual work at 0.5 MPa rather than the absolute maximum, which means it can comfortably lift a 5.1 kg component vertically with a 2:1 safety margin. The R back cover routes air axially in from the rear to save space. Because this SKU includes the -S magnet, you can mount CMSG, DMSG or EMSG sensors directly for position detection. Fixed TPU bumper pads absorb the impact at stroke end without needing manual adjustment.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SR Is Used
Short-Stroke Clamping
Secures small aluminium brackets in a CNC machining fixture using 100.5 N of push force at 0.5 MPa.
Package Diverting
Actuates a short 20 mm diverter gate on a packaging conveyor to sort small cartons.
Lab Sample Ejection
Pushes processed test tubes out of a centrifuge carousel in wet laboratory environments.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SR the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore yields 56.5 N of push at 0.5 MPa, while stepping up to a 20 mm bore provides 157 N. This makes the 16 mm the sweet spot for moderate clamping or lifting tasks. The 1/8" port matches the bore standard, ensuring adequate flow for its 30-800 mm/s speed range.
Keep in mind that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the TPU bumpers only decelerate the stroke end rather than locking the load. To hold a vertical position securely, add an external rod lock or a pilot-operated check valve. The short 20 mm stroke keeps rod bending stress minimal even under lateral loads.
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 MI16X20SR 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. The air port is 1/8".
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 fixed TPU bumper pads only decelerate the stroke end, so use a pilot check valve for vertical loads.
