Airtac MID Series Double Rod Mini Cylinder MID25X15
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X15 is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 15mm 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 MID25X15
Delivering 206.1 N of thrust at 0.5 MPa in both directions, this AirTAC MID25X15 is a round-body stainless-steel mini cylinder built for double-acting operation. Because a Ø10 mm piston rod exits both end covers, the extend and retract areas are identical, ensuring equal force while naturally resisting rotation and side loads. The 1/8" port and M10x1.25 male rod thread drop right into standard ISO 6432 mini-cylinder mounting interfaces.
The through-rod design leaves the back rod end completely free to trip a switch, carry a mechanical stop, or drive a secondary load without requiring an external guide. For this 25 mm bore, a safe working load is approximately 124 N (about 60% of the 0.5 MPa figure), yielding a vertical lift capacity of roughly 10.5 kg with a 2:1 safety margin. The stainless barrel and rod withstand mild corrosion and washdown environments. Note that this specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors; adding the -S variant enables sensing.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X15 Is Used
Symmetric Part Shuttle
Ideal for moving lightweight components between stations over its 15 mm travel, using the equal 206.1 N force to push and pull a fixture without stroke hesitation.
Mechanical Flag Trigger
The rear extending rod serves as a built-in mechanical flag, tripping a external limit switch at the end of the stroke to confirm position without needing an internal magnet.
Anti-Rotation Pin Insertion
The twin-rod construction prevents twisting during downward pressing tasks, keeping alignment true while inserting pins into housings within a washdown-capable stainless frame.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X15 the Right Cylinder?
When sizing this 25 mm bore, consider the application's force requirements: the smaller MID20 provides 131.9 N at 0.5 MPa, while the larger MID32 offers 345.6 N. This MID25X15 hits a solid middle ground with 206.1 N both ways, and its 15 mm stroke is perfect for very short, symmetric shuttle movements. The twin-rod architecture is highly recommended when you need steady, anti-rotation guidance or want to use the rear rod end to trip a remote mechanical switch.
Keep in mind that fixed TPU bumper pads only soften the stroke endpoints; they do not function as a lock. If air pressure drops, the piston will drift, so incorporate an external rod lock or pilot-operated check valve for suspended loads. For mounting, you can utilize LB foot, FA flange, or TC trunnion brackets, as well as CA, U, R, or CM back covers, but the SDB pivot-block is not available on this double-rod variant. Because this unit is non-magnetic, it cannot accept position 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 MID25X15 FAQ
Because this is a double-rod cylinder with a rod on both sides, the force is equal both ways. It delivers 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. The 1/8" port supplies air for these double-acting operations.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG, or EMSG sensors. You would need the -S variant for internal sensing. However, the double-rod design still allows the rear protruding rod to act as a physical stop or trigger for external mechanisms.
