Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SCA is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 250mm 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 MI16X250SCA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles a 250 mm stroke with a 1/8" port and an M6x1.0 male rod thread. The riveted round body uses a stainless barrel and rod to 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 conforms to ISO 6432 mounting dimensions, this Ø16 bore drops directly into standard mini-cylinder brackets and clevises. Plan for roughly 60 N of actual work at 0.5 MPa, which means it lifts about 5.1 kg vertically with a 2:1 safety margin. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SCA Is Used
Package Diverter Gate
Pivots a sorting flap on a packaging line using the CA clevis, applying 100.5 N to push light cardboard cartons onto a parallel belt.
Lab Sample Ejector
Extends 250 mm to eject filled test tube racks from a damp chemical workstation, relying on the stainless rod to resist mild corrosion.
Small Parts Escapement
Indexes plastic components out of a vibratory bowl feeder, using the -S magnet and a DMSG sensor to confirm the full 250 mm extension.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SCA the Right Cylinder?
If 100.5 N is insufficient, the Ø20 bore raises push force to 157.0 N at 0.5 MPa; if you need less power, the Ø12 bore drops to 56.5 N. This CA back cover provides a rear pivot for clevis mounting, while alternative mounts include LB foot, FA flange, SDB pivot and TC trunnion. Remember that a plain cylinder drifts when air is lost or the valve centres, so install an external rod lock or pilot check valve to hold a suspended load. At 250 mm, the M6 rod is well within the 500 mm standard limit, but always minimize side loading to prevent rod bending.
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 MI16X250SCA 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 is 1/8" and the male rod thread is M6x1.0.
It uses fixed TPU bumper pads to decelerate at the stroke end, but these do not act as a lock. The piston drifts if air is lost, so you need a pilot check valve or external rod lock to hold a load. The included -S magnet allows CMSG, DMSG and EMSG switches for position sensing.
