About the Airtac MID Series Double Rod Mini Cylinder MID40X200
Delivering 527.8 N of thrust at 0.5 MPa in both directions, the AirTAC MID40X200 is a round-body mini cylinder built for symmetric actuation. Because a Ø16 mm piston rod exits both end covers, the extend and retract areas are identical, providing equal force while naturally resisting rotation and side loads without external guides.
The stainless-steel barrel and dual rods withstand mild corrosion and washdown environments. With a 200 mm stroke and a 1/4" port, it offers a safe working load of about 317 N, moving roughly 26.9 kg vertically each way with a 2:1 safety margin. Note this non-magnetic SKU cannot host sensors; adding the -S option enables CMSG, DMSG, or EMSG switches.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac MID Series Double Rod Mini Cylinder MID40X200 Is Used
Symmetric Shuttle Drive
Use the 527.8 N equal force to push a 200 mm shuttle back and forth, relying on the twin rod to prevent twisting during rapid transfers.
Dual-End Rejector
Trip a physical flag or actuate a secondary mechanism with the rear rod extension while the front rod pushes a heavy item off the line.
Guided Press Mechanism
Press or stamp components steadily using the anti-rotation properties of the dual rod, avoiding the need for bulky external guide rails.
Is the Airtac MID Series Double Rod Mini Cylinder MID40X200 the Right Cylinder?
For lighter duties requiring less than 527.8 N at 0.5 MPa, the MID32 delivers 345.6 N both ways. If your application exceeds this 40 mm bore, there is no larger MID size, so you would need to explore different series for higher force. The through-rod design shines when you need a back-rod connection to trip a switch, carry a stop, or drive a second load simultaneously.
Keep in mind the fixed TPU bumper pads only soften the stroke end; they do not lock the piston. If air pressure drops, the cylinder drifts, so install an external rod lock or pilot check valve for suspended loads. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot block is unavailable here), and rely on CA, U, R, or CM back covers.
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 MID40X200 FAQ
It delivers an equal 527.8 N of force at 0.5 MPa and 738.9 N at 0.7 MPa in both directions, with a maximum theoretical force of 107.6 kgf. The operating speed ranges from 30 to 800 mm/s.
No, this specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors. You must select the -S variant to enable magnetic switching. The stainless build also provides excellent mild corrosion resistance.
