Airtac MID Series Double Rod Mini Cylinder MID25X50S
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X50S 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 MID25X50S
Delivering 206.1 N of thrust at 0.5 MPa in both directions, this double-acting round-body mini cylinder uses a through-rod design so extend and retract forces stay perfectly equal. The twin rod exits both end covers to resist rotation and side load, providing steadier guiding for light jobs without needing an external guide. Its stainless-steel barrel and rod withstand mild corrosion and washdown environments.
Because the rod occupies each side, both faces use the rod-side area, yielding 288.5 N at 0.7 MPa. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the 1/8" port feeds air to drive the 30-800 mm/s speed range. For a practical buyer insight, the safe working load is about 124 N, meaning it can vertically lift roughly 10.5 kg with a 2:1 safety margin.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X50S Is Used
Guided Shuttle Transfer
Pushes a 10 kg workpiece between conveyors using equal 206.1 N force both ways, relying on the twin rod to prevent rotation during the transfer.
Back-Rod Switch Trip
Uses the extended rear rod end to physically trip an external limit switch, while the built-in magnet triggers CMSG sensors for dual confirmation.
Symmetric Flap Folder
Drives a packaging flap folder from both ends simultaneously, ensuring steady, side-load-resistant motion in mildly corrosive washdown zones.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X50S the Right Cylinder?
If you need less force, the MID20X50S offers 131.9 N at 0.5 MPa, while stepping up to the MID32X50S provides 345.6 N. This 25 mm bore hits a solid middle ground, and its through-rod design is ideal when you need anti-rotation stability, a back-rod end to trip a switch, or a symmetric shuttle drive. The back rod end is free to carry a flag or stop without extra hardware.
This model uses fixed TPU bumper pads to decelerate the stroke end, but they are not a lock; the piston will drift on air loss, so use an external rod lock or pilot check valve for held loads. You can mount it via LB foot, FA flange, or TC trunnion (the SDB pivot-block is not available on double-rod variants), and the -S magnet enables CMSG, DMSG and EMSG sensors.
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 MID25X50S FAQ
It delivers equal force both ways because the rod exits each end: 206.1 N at 0.5 MPa, 288.5 N at 0.7 MPa, and a maximum theoretical force of 42.0 kgf at 1.0 MPa. The air port is 1/8".
No, the piston will drift on air loss. The fixed TPU bumpers only decelerate the stroke end and do not act as a brake. For holding a vertical load, install an external rod lock or pilot-operated check valve. The -S magnet enables position sensing.
