Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 175mm 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 MI20X175SCA
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 175 mm stroke with a sturdy Ø8 mm piston rod. The riveted barrel and rod shrug off mild corrosion, outperforming painted alternatives in damp or washdown settings. 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.
The built-in piston magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for position sensing. Because the bore falls within the Ø8-Ø25 range, it uses the ISO 6432 mounting interface, dropping smoothly into standard mini-cylinder brackets. The CA rear cover provides an integrated pivot clevis for articulated rod-end loads, while fixed TPU bumper pads absorb end-of-stroke impacts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SCA Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using the 157 N extend force, with the CA clevis allowing the gate to pivot smoothly during actuation.
Lab Sample Ejection
Ejects plastic sample tubes from a test carousel; the stainless construction prevents corrosion in humid laboratory environments.
Textile Yarn Guide
Shifts a yarn guide across a 175 mm path, relying on the -S magnet and DMSG switches to confirm positioning for the next weaving cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SCA the Right Cylinder?
If 157 N at 0.5 MPa is too much, the Ø16 bore supplies 100.5 N; if you need more muscle, the Ø25 bore steps up to 245.3 N. This 175 mm stroke is well within the 500 mm maximum for the Ø20 bore, but on longer extensions you should watch for side-loading and rod bending. The CA pivot clevis on the back cover is ideal for articulating mechanisms that require self-alignment.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only soften the stroke end and will not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. The 1/8" port matches the bore size to maintain adequate flow for the 30-800 mm/s speed range.
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 MI20X175SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8" (PT standard, G optional) and the male rod thread is M8x1.25.
No, the piston drifts if air is lost or the valve centres, so you need an external rod lock or pilot check valve to hold a load. It features fixed TPU bumper pads that decelerate the stroke end, not an adjustable air cushion. The -S magnet allows CMSG, DMSG and EMSG sensors, and the CA rear cover provides a pivot clevis.
