Airtac MID Series Double Rod Mini Cylinder MID16X40
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID16X40 is a genuine double acting, double rod 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 MID Series Double Rod Mini Cylinder MID16X40
Delivering 86.4 N of thrust at 0.5 MPa in both directions, this AirTAC MID16X40 is a round-body stainless-steel mini cylinder built for double-acting operation. Because a Ø6 mm piston rod exits both end covers, the extend and retract areas are identical, ensuring perfectly symmetrical force. The riveted stainless barrel and rod provide reliable mild corrosion and washdown resistance for industrial environments.
Conforming to the ISO 6432 mounting interface for standard mini brackets, the twin-rod design inherently resists rotation and side loads without needing an external guide. For light-duty tasks, the rear rod end is free to trip a switch or carry a mechanical stop. Based on the 0.5 MPa rating, it handles a safe working load of roughly 52 N, or lifts about 4.4 kg vertically with a 2:1 safety margin. Air connects via a 1/8" port.

Where the Airtac MID Series Double Rod Mini Cylinder MID16X40 Is Used
Symmetric Shuttle Transfer
Moves small parts between stations with 86.4 N of equal force, using the through-rod to push and pull a carriage without twisting.
Guided Stamping Press
The twin Ø6 mm rods resist side loading and rotation during light stamping tasks, maintaining alignment without external guides.
Back-Rod Stopper Arm
Uses the rear rod extension to trip a mechanical limit switch or act as a physical stop, synchronizing a 40 mm stroke cycle.
Is the Airtac MID Series Double Rod Mini Cylinder MID16X40 the Right Cylinder?
When sizing this 16 mm bore, consider that the smaller MID12X40 provides 42.4 N at 0.5 MPa, while stepping up to the MID20X40 yields 131.9 N. Choose this 86.4 N model when your application requires steady guided pushes or symmetric shuttle movements where the twin rod prevents twisting. The back rod can also drive a secondary load or flag.
Note that this SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is unavailable for double-rod types). Fixed TPU bumper pads decelerate the stroke ends, but they do not lock the piston; if air pressure drops, the load will drift, requiring an external rod lock or pilot check valve for secure holding.
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 MID Series Double Rod Mini Cylinder MID16X40 FAQ
Because the double-rod design occupies both sides, force is equal both ways. It provides 86.4 N at 0.5 MPa, 120.9 N at 0.7 MPa, and a maximum theoretical output of 17.6 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSG, DMSG, or EMSG sensors. The stainless steel build resists mild corrosion, and the 1/8" port ensures reliable airflow.
