Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40CM is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 40mm 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 MI16X40CM
Delivering 100.5 N of push force at 0.5 MPa, the AirTAC MI16X40CM is a double-acting round-body mini cylinder built for compact automation. Its stainless-steel barrel and Ø6 mm piston rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke extremes. Because this 40 mm stroke unit lacks the -S suffix, it cannot host a magnetic sensor; adding the -S magnet variant is required to use CMSG, DMSG or EMSG switches.
For practical sizing, plan for about 60 N of real work at 0.5 MPa rather than the absolute maximum, which translates to lifting a 5.1 kg part vertically with a safe 2:1 margin. The Ø16 bore uses a 1/8 inch port and an M6x1.0 male rod thread. Conforming to ISO 6432 mounting dimensions, this model drops directly into standard mini-cylinder brackets and clevises, and its CM round rear cover provides a clean, versatile back-end profile for tight spaces.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40CM Is Used
Small Part Ejection
Uses the 100.5 N push force to knock lightweight plastic mouldings off an injection press platen without damaging the part surface.
Package Diverting
Extends 40 mm to push small cardboard cartons from a main belt to a secondary packaging lane in tight layout constraints.
Lab Sample Handling
The stainless build resists humidity in environmental test chambers, actuating a 5.1 kg sample tray with reliable double-acting motion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40CM the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore yields 56.5 N of push at 0.5 MPa, while stepping up to a 20 mm bore provides 157 N. If your application requires position holding, remember that a plain double-acting cylinder drifts when air is lost or the valve is centered—the TPU bumpers only decelerate the end of stroke and act purely as an impact buffer, never as a lock or brake. To suspend a load safely, fit an external rod lock or a pilot-operated check valve.
The 40 mm stroke is well within the 500 mm maximum standard stroke for this bore, keeping the rod bending risk low even under slight side loads. You can mount this unit using LB foot brackets, FA flanges, SDB pivot blocks or TC trunnions. Just ensure you select the -S magnet version if your control system needs end-of-stroke feedback, as this specific SKU is not sensor-ready.
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 MI16X40CM FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa. This 16 mm bore model features a 1/8 inch port and an M6x1.0 male rod thread.
Yes, it shares ISO 6432 mounting dimensions, so it fits standard mini-cylinder clevises and foot brackets like LB, FA, SDB and TC. However, because this SKU lacks the -S suffix, it has no magnet and cannot accept CMSG, DMSG or EMSG sensors; you must order the -S variant for position feedback.
