Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15CAH
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15CAH is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 15mm 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 MI20X15CAH
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 15 mm strokes with precision. The riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. It uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.
Equipped with a CA pivot clevis and a high-temperature Viton seal (-H), it suits hot environments up to the datasheet limit. The 1/8" port feeds the 8 mm rod, and fixed TPU bumper pads absorb the stroke-end impact. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift about 8 kg vertically against gravity.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15CAH Is Used
Clamp Ejection
Short 15 mm stroke pops small finished parts out of an injection moulding die using 157 N of push force.
Diverter Gate
Pivots a guide flap via the CA clevis to sort lightweight cartons on a washdown packaging line.
Pilot Actuation
Trips a process valve in a high-temperature zone, relying on the Viton FKM seals for longevity.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15CAH the Right Cylinder?
When sizing this 20 mm bore, the 16 mm option offers 100.5 N push at 0.5 MPa, while the 25 mm provides 245.3 N, letting you step up or down based on your exact load. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors; add the -S variant if you need position detection. The CA rear pivot cover is ideal for articulating clevis mounts.
Because this is a very short 15 mm stroke, side-load and rod-bending stresses are minimal, but you must still align the pivot accurately. Remember that a plain double-acting cylinder drifts if air pressure is lost or the valve is centred; the bumpers only decelerate the end of travel and will not lock the load. Fit an external rod lock or pilot check valve if you need to hold position.
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 MI20X15CAH FAQ
This 20 mm bore cylinder has a 1/8" port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, it uses the ISO 6432 mounting interface for standard brackets and clevises. However, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors; you need the -S variant for position sensing.
