Airtac MI16-20 Stainless Steel Mini Cylinder MI20X105SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X105SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 105mm 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 MI20X105SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes, while the riveted construction keeps the body compact.
Because it carries the -S suffix, an internal piston magnet is included for direct mounting of CMSG, DMSG or EMSG sensors. For actual work, plan for around 94 N of usable load at 0.5 MPa rather than the absolute maximum. This translates to lifting an 8 kg part vertically with a safe 2:1 margin. The CA rear pivot cover allows clevis mounting, and the unit operates at speeds between 30 and 800 mm/s.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X105SCA Is Used
Package Diverter Arm
Pivots a deflector plate on a packaging line to sort medium-weight cartons, utilizing the 157 N push force and CA clevis mount for smooth articulation.
Textile Loom Tensioner
Maintains consistent yarn tension by extending and retracting a guide roller, relying on the stainless construction to endure humid manufacturing environments.
Parts Ejection Gate
Pushes finished metal components out of a CNC machining enclosure, using the 105 mm stroke and integrated sensor magnet to confirm ejection completion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X105SCA the Right Cylinder?
When sizing this unit, the smaller Ø16 bore provides 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N. This 157 N unit sits right in the middle for medium-duty jobs. The 105 mm stroke is well within the 500 mm maximum, but at this extension you should still minimize side-loading to prevent rod bending. The CA back cover provides a pivot mount for articulated mechanisms.
Remember that a standard cylinder drifts when air pressure is lost or the valve is centered; the TPU bumpers only soften the end of stroke and do not act as a brake. To hold a vertical load securely, add an external rod lock or a pilot-operated check valve. The built-in magnet (-S) supports position sensing, and the body conforms to ISO 6432 mounting dimensions for straightforward bracket integration.
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 MI20X105SCA FAQ
This Ø20 mm cylinder features a 1/8" port and an M8x1.25 male rod thread. 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 force of 32 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston at the stroke end and do not function as a lock; you need an external rod lock or pilot check valve to hold a load. It features a CA rear pivot cover for clevis mounting and uses standard ISO 6432 dimensions. The -S magnet allows CMSG, DMSG, or EMSG sensors for position detection.
