About the Airtac MID Series Double Rod Mini Cylinder MID25X100S
Delivering 206.1 N of thrust at 0.5 MPa in both directions, the AirTAC MID25X100S is a 25 mm bore, double-acting through-rod mini cylinder. Because a Ø10 mm piston rod exits both end covers, the extend and retract areas are identical, yielding perfectly symmetric force. The twin-rod architecture inherently resists rotation and side loads, providing stable guiding for light-duty tasks without requiring an external guide rail. Its stainless-steel round barrel and rod offer reliable mild corrosion and washdown resistance.
This 100 mm stroke unit conforms to the ISO 6432 mounting interface for straightforward bracket and clevis integration. It features a 1/8" port and an M10x1.25 male rod thread. For buyers sizing components, a safe working load is roughly 124 N (about 60% of the 0.5 MPa force), which translates to vertically lifting around 10.5 kg with a 2:1 safety margin. The included -S piston magnet supports CMSG, DMSG, and EMSG position sensing.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X100S Is Used
Symmetric Shuttle Transfer
With 206.1 N of equal force both ways, this cylinder drives a 25 mm shuttle mechanism back and forth without speed or power disparity between strokes.
Rear-Rod Switch Trip
The extended back rod provides a convenient mounting point to physically trigger a limit switch or carry a flag, eliminating the need for extra sensor brackets.
Anti-Rotation Guiding
The twin through-rod resists torsional twisting under offset loads, keeping a 10.5 kg vertical lift steady without requiring an external linear guide.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X100S the Right Cylinder?
If you need slightly less push, the MID20 bore provides 131.9 N at 0.5 MPa; stepping up to the MID32 yields 345.6 N. The MID25X100S 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. You can mount it via LB foot, FA flange, or TC trunnion, but note the SDB pivot-block is not available for this double-rod variant. Fixed TPU bumper pads decelerate the stroke ends, but they do not lock the piston; if air pressure drops, the load will drift, requiring an external rod lock or pilot check valve for secure holding.
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 MID25X100S FAQ
The MID25X100S delivers equal force in both directions because a rod occupies each side. It outputs 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. It uses a 1/8" port.
The double through-rod resists rotation and side loads while offering a rear rod end for secondary stops or switches. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors, and the stainless build handles mild washdowns.
