Airtac MID Series Double Rod Mini Cylinder MID20X25TC
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID20X25TC is a genuine double acting, double rod round-body mini air cylinder with a Ø20mm bore and 25mm 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 MID20X25TC
Delivering 131.9 N of thrust at 0.5 MPa in both directions, the AirTAC MID20X25TC is a double-acting, through-rod mini cylinder built for symmetric loads. Because a rod exits both end covers, the extend and retract areas are identical, completely eliminating the force differential found in single-rod units. The twin rod also resists rotation and side load, providing steadier guiding for light jobs without needing an external guide.
This round-body unit features a stainless-steel barrel and rod for mild corrosion and washdown resistance, and it conforms to the ISO 6432 mounting interface for standard mini brackets. It uses a 1/8" port and an M8x1.25 male rod thread. Based on the 0.5 MPa rating, the safe working load is about 79 N, which means it can vertically lift roughly 6.7 kg with a 2:1 safety margin. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MID Series Double Rod Mini Cylinder MID20X25TC Is Used
Symmetric Shuttle
With 131.9 N of equal force both ways, this cylinder smoothly drives a lightweight shuttle or indexing carrier back and forth without speed or power discrepancies between strokes.
Guided Push Station
The twin through-rod resists rotation during a 25 mm push, keeping a small stamping or clamping head perfectly aligned on the workpiece without requiring an external guide rail.
Back-Rod Switch Trip
The exposed rear rod end provides a convenient, moving surface to physically trip an external mechanical limit switch or carry a physical stop flag for position confirmation.
Is the Airtac MID Series Double Rod Mini Cylinder MID20X25TC the Right Cylinder?
If you need less force, the MID16 bore provides 86.4 N at 0.5 MPa; if you need more, stepping up to the MID25 yields 206.1 N. Choose this double-rod configuration 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. This model includes a TC trunnion mounting accessory, though the SDB pivot-block is not available on double-rod variants. Remember that the fixed TPU bumper pads only soften the stroke end; they do not lock the piston. If your application must hold a load on air loss, install an external rod lock or pilot-operated check valve.
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 MID20X25TC FAQ
Yes, force is equal both ways because the double-rod design has a rod on each side. It delivers 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a maximum theoretical force of 26.9 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
No, this specific SKU does not include a magnet, so it cannot be used with CMSG, DMSG, or EMSG sensors. You would need the -S variant for magnetic sensing. The stainless steel build resists mild corrosion, and it uses a 1/8" port.
