Airtac MI16-20 Stainless Steel Mini Cylinder MI16X90U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X90U is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 90mm 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 MI16X90U
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The riveted barrel and Ø6 mm rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. The 1/8" port and M6x1.0 male rod thread are determined by the 16 mm bore.
Because the bumper pads only decelerate the stroke end rather than locking the rod, you can plan for a safe working load of about 60 N. That translates to lifting roughly 5.1 kg vertically with a 2:1 safety margin. This specific SKU features a 90-degree U back cover for perpendicular port orientation but lacks a magnet, meaning it cannot host CMSG, DMSG or EMSG sensors without upgrading to an -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X90U Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, where the 100.5 N push force easily overcomes flap friction and the stainless build survives humid packing rooms.
Lab Sample Ejection
Pushes processed sample trays out of a testing station, utilizing the 90 mm stroke and 90-degree U cover to keep air lines neatly tucked perpendicular to the motion path.
Small Press Ejector
Ejects small stamped parts from a die, relying on the fixed TPU bumper pads to absorb the end-of-stroke impact without requiring an adjustable air cushion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X90U the Right Cylinder?
When sizing this 16 mm bore, verify your actual load against the 100.5 N push at 0.5 MPa. If your application requires less force, stepping down to the Ø12 bore provides 56.5 N, while moving up to the Ø20 bore yields 157.0 N. The 90 mm stroke is well within the 500 mm maximum standard stroke, keeping the unit readily available without made-to-order delays.
Remember that a plain double-acting cylinder drifts when air is lost or the valve is centred; the fixed TPU bumpers only soften impact and do not act as a brake. To hold a vertical load securely, add an external rod lock or a pilot-operated check valve. You can mount this unit using LB foot, FA flange, SDB pivot or TC trunnion hardware.
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 MI16X90U FAQ
This 16 mm bore cylinder features a 1/8" 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, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG or EMSG switches. You would need the -S variant for sensor compatibility. It uses standard ISO 6432 mounting dimensions and a 90-degree U back cover for flexible installation.
