Airtac MI16-20 Stainless Steel Mini Cylinder MI16X140SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X140SCA is a genuine double acting round-body mini air cylinder with a Ø16mm 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 MI16X140SCA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 140 mm stroke with a 1/8 inch air port. The riveted stainless barrel and Ø6 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke ends, decelerating the piston smoothly without the complexity of adjustable cushions.
Because the Ø16 bore falls within the Ø8-Ø25 range, it uses the standard ISO 6432 mounting dimensions, dropping easily into existing mini-cylinder brackets. For practical sizing, plan for about 60 N of real work at 0.5 MPa, which translates to lifting a 5.1 kg part vertically with a 2:1 safety margin. The built-in magnet supports CMSG, DMSG and EMSG switches for position sensing.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X140SCA Is Used
Textile Loom Guide
Shifts a yarn guide carriage through 140 mm of travel, where the stainless build resists humid dye-room conditions.
Package Diverter Arm
Actuates a routing flap on a packaging line, using the CA pivot bracket to accommodate the swing arc.
Small Part Ejector
Pushes lightweight molded trays off an assembly table using a safe working load of roughly 60 N.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X140SCA the Right Cylinder?
When sizing this 16 mm bore, stepping down to the Ø12 model drops the push force to 56.5 N at 0.5 MPa, while moving up to the Ø20 bore increases it to 157.0 N. The included CA rear pivot cover suits articulated or clevis-mounted mechanisms, and the -S magnet enables electronic or reed sensor tracking. Keep in mind that a plain double-acting cylinder drifts if air pressure is lost or the valve is centred; the TPU bumpers only soften the end of stroke and will not lock the load. Use an external pilot check valve or rod lock if you need to hold a vertical position safely.
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 MI16X140SCA FAQ
This Ø16 mm cylinder features a 1/8 inch air port and an M6x1.0 male rod thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum of 20.5 kgf at 1.0 MPa.
No, the piston will drift if air pressure drops or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must add an external rod lock or pilot-operated check valve to hold a vertical load safely.
