Airtac MID Series Double Rod Mini Cylinder MID25X50
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X50 is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 50mm 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 MID25X50
Delivering 206.1 N of thrust in both directions at 0.5 MPa, this stainless steel round-body mini cylinder uses a through-rod design that resists rotation and side load. Because the Ø10 mm piston rod exits both end covers, the extend and retract forces are perfectly equal, making it ideal for guiding steady pushes without needing an external guide. The 1/8" port feeds the double-acting chambers, operating at speeds from 30 to 800 mm/s.
Built with a riveted stainless barrel and rod, it handles mild washdown environments and conforms to the ISO 6432 mounting interface for standard mini brackets. Based on the 0.5 MPa rating, it provides a safe working load of roughly 124 N, or a vertical lift of about 10.5 kg with a 2:1 margin. This base SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without the -S option.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X50 Is Used
Symmetric Shuttle Transfer
Drives a 10.5 kg payload back and forth with equal 206.1 N force, using the twin rod to keep the carrier steady without external guides.
Back-Rod Switch Tripping
Uses the protruding rear rod end to physically trip a limit switch or carry a flag, confirming stroke completion on a 50 mm cycle.
Guided Push Assembly
Presses small components with a 124 N safe working load, relying on the anti-rotation properties of the double rod for precise alignment.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X50 the Right Cylinder?
For lighter duties, the MID20X50 provides 131.9 N at 0.5 MPa, while stepping up to the MID32X50 yields 345.6 N if you need more force. The through-rod configuration is perfect when you need to mount a stop or trip a switch on the back rod end, or drive a symmetric shuttle. Remember that the fixed TPU bumpers only soften the stroke end; they do not lock the piston, so use an external rod lock or pilot check valve to hold a load on air loss.
You can mount this cylinder using LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers, but the SDB pivot block is not available for double-rod types. Because this specific SKU has no magnet, position sensing is impossible unless you select the -S magnet version.
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 MID25X50 FAQ
Because it is a double-rod cylinder, the force is equal both ways: 206.1 N at 0.5 MPa, 288.5 N at 0.7 MPa, and a maximum theoretical output of 42.0 kgf at 1.0 MPa.
No, this base SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors. You must choose the -S variant for position sensing. Its stainless steel riveted construction also provides excellent mild corrosion resistance.
