Airtac MID Series Double Rod Mini Cylinder MID25X200S
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X200S is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 200mm 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 MID25X200S
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 to equalize extend and retract forces. The twin rod resists rotation and side loads, keeping guiding steady for light jobs, while the back rod end remains free to trip a switch or carry a stop. Because a rod exits both ends, the effective area is identical on each side. The Ø25 bore features a 1/8" port and a male M10x1.25 rod thread. Its riveted stainless barrel and piston rod withstand mild corrosion and washdown environments. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing, and the body conforms to the ISO 6432 mounting interface for standard mini brackets. Operating speed ranges from 30-800 mm/s.
For practical sizing, the 206.1 N output at 0.5 MPa yields a safe working load of about 124 N. Applied vertically, it moves roughly 10.5 kg each way with a 2:1 safety margin. Fixed TPU bumper pads decelerate the piston near stroke ends, though they do not lock the load. If air pressure drops, the piston will drift; secure suspended loads with an external rod lock or pilot check valve.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X200S Is Used
Guided Push Station
With 206.1 N of equal force, the twin rod resists rotation to deliver steady, guided pushes for assembly tooling over the 200 mm travel.
Back-Rod Switch Trip
The rear protruding rod end trips an external limit flag or CMSG sensor without needing extra space on the primary work end.
Symmetric Shuttle
Moving approximately 10.5 kg vertically each way with a 2:1 margin, the through-rod drives a symmetric parts shuttle that pushes and pulls equally.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X200S the Right Cylinder?
When sizing this 200 mm stroke unit, consider the next MID bore down (Ø20, 131.9 N at 0.5 MPa) for lighter pushes, or step up to the Ø32 (345.6 N at 0.5 MPa) for heavier loads. The double-rod configuration is ideal when you need anti-rotation stability, a back-rod stop, or symmetric shuttle movements. Mounting options include LB foot, FA flange, and TC trunnion brackets (the SDB pivot-block is not available on this double-rod variant). Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors without modification.
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 MID25X200S FAQ
It delivers equal force both ways because the double-rod design uses the rod-side area on each face. It provides 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.
No, the piston will drift on air loss. The fixed TPU bumpers only decelerate the stroke end; they do not lock the load. Use an external rod lock or pilot check valve for holding. The -S magnet enables position sensing via CMSG, DMSG, or EMSG switches.
