Airtac MID Series Double Rod Mini Cylinder MID25X65
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X65 is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 65mm 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 MID25X65
Delivering 206.1 N of thrust at 0.5 MPa in both directions, the AirTAC MID25X65 is a double-acting, through-rod mini cylinder. Because a Ø10 mm piston rod exits both end covers, the extend and retract areas are identical, providing equal force while naturally resisting side load and rotation without an external guide. The stainless-steel round barrel and dual rods offer reliable mild corrosion and washdown resistance.
This Ø25 mm bore unit uses a 1/8" port and conforms to the ISO 6432 mounting interface for easy bracket integration. It operates at speeds from 30-800 mm/s and relies on fixed TPU bumper pads to decelerate the stroke ends. For sizing, this specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors; adding the -S option enables that capability. Based on the 0.5 MPa rating, it handles a safe working load of roughly 124 N, easily moving about 10.5 kg vertically each way with a 2:1 safety margin.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X65 Is Used
Symmetric Shuttle Transfer
With 206.1 N of equal force both ways, this cylinder reliably pushes a 10.5 kg shuttle back and forth between two stations without twisting.
Back-Rod Switch Trip
The extended rear rod provides a convenient mounting point to physically trip a limit switch or carry a flag, keeping the front workspace clear for tooling.
Guided Push Operation
The twin Ø10 mm rods resist rotation and side load during light pressing or aligning tasks, maintaining steady contact without needing an external guide.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X65 the Right Cylinder?
When sizing this 25 mm bore, consider the next size down (MID20) which provides 131.9 N at 0.5 MPa, or the larger MID32 which yields 345.6 N. This MID25X65 hits a sweet spot at 206.1 N both ways. The through-rod design is ideal when you need to trip a switch or carry a stop flag on the back rod end, or drive a symmetric shuttle. Note that the SDB pivot-block is unavailable for this double-rod variant; use LB, FA, or TC mounts instead. Remember that a plain cylinder drifts on air loss—the TPU bumpers only soften the stroke end, so add an external rod lock or pilot check valve if you must hold a load.
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 MID25X65 FAQ
The MID25X65 delivers equal force in both directions 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, this specific SKU does not include a magnet and cannot host CMSG, DMSG, or EMSG sensors. You would need the -S variant for sensing. The stainless-steel build resists mild corrosion, and the 1/8" port ensures standard air connections.
