Airtac MI16-20 Stainless Steel Mini Cylinder MI16X120SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X120SCA is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 120mm 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 MI16X120SCA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles 120 mm of travel with a Ø6 mm piston rod. The riveted round-body construction shrinks the footprint while the stainless barrel and rod resist mild corrosion in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke ends to protect your mechanism. Because the bore is Ø16, it shares the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.
For real-world sizing, plan for roughly 60 N of actual work at 0.5 MPa rather than the absolute maximum. That translates to lifting about 5.1 kg vertically with a safe 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG position switches, while the CA rear cover provides a pivot clevis for articulated linkages. Air connects via 1/8" ports.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X120SCA Is Used
Textile Loom Guide
Shifts a yarn guide arm through 120 mm of travel, using the CA pivot to maintain alignment while the stainless body tolerates humid weaving environments.
Package Sorting Diverter
Pushes light cardboard cartons off a main belt, providing 60 N of safe working force to deflect items without crushing the packaging.
Lab Sample Ejector
Extends 120 mm to eject filled test tube racks from a dispenser, relying on CMSG sensors to confirm the full extension stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X120SCA the Right Cylinder?
If 100.5 N is too much force, step down to the Ø12 bore which yields 56.5 N at 0.5 MPa; if your mechanism requires more power, the Ø20 bore pushes 157.0 N. This 120 mm stroke sits well within the 500 mm maximum for this bore, though at extended lengths you should verify side-loading to avoid bending the Ø6 mm rod. The CA pivot cover requires a matching clevis pin to function correctly.
Remember that venting the air or centering the valve lets the piston drift freely, as the TPU pads only soften the end of travel rather than locking the rod. To suspend a load securely during an air loss event, install an external rod lock or a pilot-operated check valve.
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 MI16X120SCA FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N. At 0.7 MPa it pushes 140.7 N and pulls 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port size is 1/8".
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumpers only decelerate the stroke end and do not act as a brake. To hold a load, you must add an external rod lock or a pilot check valve.
