Airtac MID Series Double Rod Mini Cylinder MID25X30
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X30 is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 30mm 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 MID25X30
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 that resists rotation and side load. Because a rod exits both end covers, the extend and retract areas are identical, ensuring perfectly symmetric force. The 1/8" port and M10x1.25 male rod thread equip this Ø25 bore for demanding light-duty work.
The double-rod layout leaves the back rod end free to trip a switch or carry a mechanical stop without needing an external guide. It conforms to the ISO 6432 mounting interface for easy bracket integration, and the stainless barrel handles mild washdown environments. This non-magnet SKU cannot host a sensor; add the -S option for CMSG, DMSG or EMSG switches.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X30 Is Used
Symmetric Shuttle Transfer
Pushes a 10 kg jig back and forth on a linear rail, using the equal 206.1 N force both ways to maintain a consistent rhythm without needing a separate external guide.
Back-Rod Switch Trip
Uses the protruding rear rod end to physically strike an external mechanical limit switch, confirming stroke completion without requiring an internal cylinder magnet.
Guided Carton Rejector
Steadily pushes misaligned cartons off a conveyor belt, relying on the twin rod's resistance to twisting and side load to keep the rejection paddle perfectly straight.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X30 the Right Cylinder?
With a 206.1 N output at 0.5 MPa, this bore safely moves a 124 N load or vertically lifts about 10.5 kg with a 2:1 safety margin. If your application is lighter, stepping down to the MID20X50 provides 131.9 N, while heavier payloads require the MID32X50 at 345.6 N. The twin-rod architecture is ideal when you need steady guided pushes or a back-rod stop.
Note that the fixed TPU bumper pads only soften the stroke end and do not lock the piston; if air pressure drops, the cylinder drifts, so fit an external rod lock or pilot check valve for held loads. Mounting options include LB foot, FA flange and TC trunnion (the SDB pivot block is unavailable here). Speeds run 30-800 mm/s.
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 MID25X30 FAQ
Because it is a double-rod cylinder, 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" air port.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant to enable sensing. The stainless steel build and fixed TPU bumpers are standard.
