Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 230mm 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 MI20X230CM
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles mid-range automation tasks with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread, while the CM round end cover keeps the rear profile smooth for tight installations. Its riveted stainless barrel and rod shrug off mild corrosion better than painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes, though they only decelerate rather than providing adjustable cushioning. For practical sizing, plan for around 94 N of real work at 0.5 MPa, which equates to lifting an 8 kg part vertically with a safe 2:1 margin. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.
Conforming to the ISO 6432 mounting interface, the unit drops directly into standard mini-cylinder brackets and clevises without custom hardware. The 230 mm stroke sits well within the 500 mm maximum limit for this bore, yet at this length you should watch for side-loading and rod bending to prevent premature seal wear.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230CM Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using 157 N of thrust, with the stainless build resisting humid packing-room environments.
Vertical Parts Lift
Raises 8 kg fixture trays through a 230 mm stroke, matching the safe 2:1 vertical lift capacity derived from the 0.5 MPa push rating.
Textile Loom Tensioner
Positions yarn guide arms repeatedly at speed, relying on the 1/8" port for rapid air exchange and fixed TPU pads to soften stroke-end impact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230CM the Right Cylinder?
When sizing this actuator, weigh it against its neighbours: step down to a Ø16 bore for roughly 100 N of push at 0.5 MPa, or step up to a Ø25 bore for 245 N if the load demands more authority. Keep in mind that a standard double-acting cylinder drifts when air is removed or the valve is centred—the TPU bumpers only soften the end of travel and will not lock or hold the load. For vertical or suspended loads, fit an external rod lock or a pilot-operated check valve. You can mount the body via LB foot, FA flange, SDB pivot or TC trunnion hardware, and the rear CM round cover suits compact spatial layouts. If your cycle demands end-deceleration tuning rather than fixed bumpers, look at the MIC variable-cushion variant.
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 MI20X230CM FAQ
This Ø20 mm bore cylinder features a 1/8" port and an Ø8 mm rod. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration, not an adjustable air cushion.
