Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 140mm 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 MI20X140SCM
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 riveted 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 without offering adjustable cushioning.
Because it carries the -S suffix, a built-in piston magnet supports CMSG, DMSG, and EMSG switches for position sensing. In practical terms, you can expect a safe working load of roughly 94 N at 0.5 MPa. For vertical lifting, that translates to hoisting about 8 kg safely with a 2:1 margin, letting you match the cylinder to real part weights without overloading the rod.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140SCM Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using its 8 kg safe vertical lift capacity and 140 mm travel.
Textile Loom Tensioner
Maintains consistent yarn tension in humid textile facilities where the stainless steel barrel prevents mild corrosion.
Bin Lid Actuator
Opens and closes access hatches on material bins, relying on the CM round end cover for straightforward rear pivoting.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140SCM the Right Cylinder?
Sizing this actuator requires looking both down and up the range: the smaller Ø16 bore yields 100.5 N of push at 0.5 MPa, while the larger Ø25 bore jumps to 245.3 N, making the Ø20 the sweet spot for mid-range force. The CM round end cover dictates the rear mounting and port orientation, so verify it fits your bracket layout. If your 140 mm stroke introduces side loading, ensure adequate rod guidance to prevent premature seal wear. This unit includes the -S magnet for sensing, but remember a plain cylinder drifts when air is lost or the valve is centered; use a pilot-operated check valve if you need to hold a load mid-stroke.
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 MI20X140SCM FAQ
This Ø20 mm bore 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 of 32 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in magnet compatible with CMSG, DMSG, and EMSG switches. However, it uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable cushion. The piston will drift if air is lost or the valve is centered, so install an external rod lock or pilot check valve for load holding.
