Airtac MID Series Double Rod Mini Cylinder MID25X75S
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X75S is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 75mm 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 MID25X75S
Delivering 206.1 N of thrust at 0.5 MPa in both directions, this stainless steel round-body mini cylinder uses a through-rod design to ensure extend and retract forces remain identical. The twin rod resists rotation and side load, providing steady guidance for light jobs without needing an external guide. Its stainless barrel and rod withstand mild corrosion and washdown environments. Because the -S suffix denotes a built-in piston magnet, this unit is fully ready for CMSG, DMSG, or EMSG position sensing.
Fitted with a 1/8" port and an M10x1.25 male rod thread, it conforms to the ISO 6432 mounting interface for easy bracket integration. Operating at 30-800 mm/s, it provides a safe working load of about 124 N. For vertical lifts, expect to move roughly 10.5 kg each way with a 2:1 safety margin. Fixed TPU bumper pads decelerate the stroke ends, though they will not lock the load if air pressure drops.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X75S Is Used
Symmetric Shuttle Transfer
With 206.1 N of equal force both ways, this cylinder smoothly pushes a 10.5 kg payload back and forth between stations without stroke asymmetry.
Back-Rod Switch Trip
The extending rear rod end provides a convenient physical target to trip a limit switch or flag, confirming stroke completion without extra sensors.
Guided Push Operation
The twin through-rod resists rotation under side load, keeping a 124 N pressing tool perfectly aligned during repeated assembly tasks.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X75S the Right Cylinder?
When sizing this 25 mm bore, stepping down to the MID20X100 yields 131.9 N at 0.5 MPa, while stepping up to the MID32X75 provides 345.6 N. This model is ideal when your mechanism requires anti-rotation stability, a back-rod end to trip a switch or carry a stop, or symmetric shuttle movements. The through-rod balances forces perfectly in both directions.
Remember that a plain cylinder drifts if air loss occurs; the fixed bumpers only soften the end of stroke and do not act as a brake. For holding a suspended load, install an external rod lock or pilot-operated check valve. You can mount this unit via LB foot, FA flange, or TC trunnion, but the SDB pivot-block is not available on this double-rod variant.
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 MID25X75S FAQ
Because a rod exits both ends, 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. It uses a 1/8" port.
Yes, the -S suffix means it has a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches. The stainless steel build also provides mild washdown resistance.
