Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 75mm 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 MI20X75CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 75 mm stroke with a 1/8" port and a CM round rear cover. The rolled stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning.
For practical sizing, plan for roughly 94 N of usable work at 0.5 MPa, which translates to lifting about 8 kg vertically with a safe 2:1 margin. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors; add the -S version if you need position detection.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75CM Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line to push parcels into sorting lanes using 157 N of thrust.
Textile Loom Tensioner
Maintains consistent yarn tension in a humid textile facility, leveraging the stainless build to resist moisture.
Carton Lid Flap Folder
Folds corrugated box flaps closed on an automated packing conveyor during a 75 mm travel cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75CM the Right Cylinder?
When sizing this 20 mm bore, the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N, letting you step up or down based on your exact force needs. The CM round end cover dictates a specific rear mounting and port orientation, so verify your bracket geometry. If your 75 mm stroke carries a heavy lateral load, support the rod to prevent bending and premature seal wear.
Remember that venting the air supply or centering the control valve causes the piston to drift, as the TPU bumpers only decelerate the end of travel and act neither as a lock nor a brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
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 MI20X75CM FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa, and the air port is 1/8".
The Ø20 bore uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder clevises and brackets. However, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors without upgrading to the -S variant.
