Airtac MID Series Double Rod Mini Cylinder MID25X160
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X160 is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 160mm 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 MID25X160
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 exits both end covers. Because the piston rod occupies each side, the extend and retract forces are perfectly equal at 288.5 N at 0.7 MPa. The twin-rod architecture inherently resists rotation and side loads, providing steadier guiding for light jobs without needing an external guide.
Built with a 25 mm bore and a 160 mm stroke, it features a 1/8" port and M10x1.25 male rod threads. The stainless barrel and rod resist mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for standard mini brackets. Based on the 0.5 MPa rating, it handles a safe working load of about 124 N, meaning it can vertically lift roughly 10.5 kg with a 2:1 safety margin. This base SKU lacks a magnet and cannot support position sensing.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X160 Is Used
Symmetric Shuttle Transfer
Pushing a 10 kg component back and forth between two stations, utilizing the equal 206.1 N force in both directions for consistent bidirectional cycling.
Back-Rod Switch Tripping
Using the protruding rear rod end to mechanically trip an external limit switch, avoiding the need for internal magnets while maintaining steady guidance.
Guided Stamping Press
Applying a steady 288.5 N clamping force at 0.7 MPa where the twin rod prevents tool rotation during the stamping descent, ensuring precise alignment.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X160 the Right Cylinder?
When sizing this 25 mm bore unit, consider stepping down to a MID20 model if your load is lighter, which provides 131.9 N at 0.5 MPa. If you need more power, stepping up to a MID32 yields 345.6 N at 0.5 MPa. The double-rod layout is ideal when you need anti-rotation stability, want to use the back rod end to trip a switch or carry a stop, or need to drive a second load simultaneously. For mounting, you can use LB foot, FA flange, or TC trunnion brackets, along with CA, U, R, or CM back covers, but the SDB pivot block is not compatible with this double-rod variant.
Keep in mind that the fixed TPU bumper pads only soften the stroke end; they do not lock the piston. If air pressure drops, the cylinder will drift and cannot hold a load. To maintain position during air loss, install an external rod lock or a pilot-operated check valve. Since this specific model lacks the -S magnet option, it cannot accept CMSG, DMSG, or 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 MID25X160 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 force of 42.0 kgf at 1.0 MPa. It operates at speeds between 30-800 mm/s.
No, this specific SKU does not include a magnet. You must order the -S variant to use CMSG, DMSG, or EMSG sensors. However, the double-rod design allows the rear rod to physically trip an external switch, and the stainless build resists mild corrosion.
