Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 200mm 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 MI20X200SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 200 mm stroke with ease. 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. The riveted construction keeps the body compact, while fixed TPU bumper pads soften the impact at stroke extremes.
Because it carries the -S suffix, a built-in piston magnet is included for direct mounting of CMSG, DMSG or EMSG switches. In practice, plan for a safe working load of roughly 94 N, which translates to lifting about 8 kg vertically with a 2:1 safety margin. The CM round end back cover provides a clean rear profile for your assembly.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200SCM Is Used
Package Diverter Gate
Shifts lightweight cardboard cartons on a packaging line using the 157 N push force, with the 200 mm stroke providing ample clearance for varying box widths.
Lab Sample Ejection
Ejects plastic test tube racks from a testing carousel; the stainless construction withstands daily chemical wipe-downs and mild washdown exposure.
Bin Lid Actuation
Opens and closes hinged lids on sorting bins, where the CMSG reed switch confirms the fully open position for automated sorting logic.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200SCM the Right Cylinder?
When sizing this unit, note the Ø16 bore below offers 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N. This 157 N class is a solid middle ground for moderate actuation tasks. The 200 mm stroke is well within the 500 mm maximum standard stroke for this bore, avoiding made-to-order delays, though you should still manage side loading to prevent rod bending over that travel distance.
The ISO 6432 mounting interface on this Ø20 bore drops directly into standard mini-cylinder brackets and clevises. Remember that the fixed TPU bumpers only decelerate the end of stroke; they do not act as a brake. If your application must hold a vertical load when air pressure drops or the valve centres, you will need an external rod lock or a pilot-operated check valve to prevent drift.
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 MI20X200SCM FAQ
This Ø20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and the pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG and EMSG switches. However, it does not hold position if air is lost or the valve is centred; the piston will drift. The fixed TPU bumper pads only decelerate the stroke end and do not function as a locking brake.
