Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CAH
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CAH is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 25mm 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 MI20X25CAH
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 25 mm strokes with a rear CA pivot clevis. The -H suffix equips it with Viton (FKM) high-temperature seals, extending service life in heated environments, while the Ø8 mm piston rod uses an M8x1.25 male thread. Air connects via a 1/8" port.
Because the riveted stainless barrel and rod resist mild corrosion and washdown, this unit outlasts painted alternatives in damp processing areas. It relies on fixed TPU bumper pads to decelerate the stroke end rather than an adjustable cushion. Plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a safe 2:1 margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CAH Is Used
Hot-End Part Ejection
Uses the Viton FKM seals and CA pivot to reliably push 8 kg moulded components out of a heated jig without degrading.
Washdown Diverter
Swings a guide rail on a food packaging line, leveraging the stainless steel barrel to withstand damp washdown conditions.
Short-Stroke Clamping
Provides 157 N of clamping pressure to hold a small aluminium bracket during a light machining operation.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CAH the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm cylinder drops the push force to 100.5 N, whereas moving up to a 25 mm bore increases it to 245.3 N at 0.5 MPa. The 25 mm stroke here is well within the 500 mm maximum, keeping the Ø8 mm rod rigid with minimal side-load bending risk. You can mount it using standard ISO 6432 mini-cylinder brackets, foot blocks (LB), or flanges (FA) to suit your frame. If your mechanism must stay put during an air loss or valve centre state, remember this cylinder will drift; add an external rod lock or pilot-operated check valve to hold the load securely.
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 MI20X25CAH FAQ
This 20 mm bore cylinder uses a 1/8" air port. 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, the Ø20 mm body uses standard ISO 6432 mounting dimensions for easy bracket integration, including the built-in CA clevis. However, this SKU lacks a magnet, so you cannot mount CMSG, DMSG or EMSG magnetic switches unless you purchase the -S variant.
