About the Airtac MID Series Double Rod Mini Cylinder MID20X225S
Delivering 131.9 N of thrust at 0.5 MPa in both directions, the AirTAC MID20X225S is a double-acting, through-rod mini cylinder built for guided motion. Because a rod exits both end covers, the extend and retract areas are identical, providing equal force while resisting rotation and side loads without needing an external guide. The rear rod end is free to trip a switch or carry a stop. Its stainless-steel round barrel and rod shrug off mild corrosion and washdown environments.
This Ø20 mm bore unit features a 225 mm stroke, an M8x1.25 male rod thread, and a 1/8" port. It conforms to the ISO 6432 mounting interface for easy bracket integration. With a 0.5 MPa input, the safe working load is roughly 79 N, yielding a vertical lift capacity of about 6.7 kg with a 2:1 safety margin. The included -S magnet enables position sensing with CMSG, DMSG, or EMSG switches.

Where the Airtac MID Series Double Rod Mini Cylinder MID20X225S Is Used
Guided Push-Pull Stops
The twin-rod anti-rotation feature provides 131.9 N of perfectly symmetric force to push and pull a gauge or stop block steadily along a short linear track.
Symmetric Shuttle Transfer
Moving about 6.7 kg of vertical load each way, the through-rod design shuttles a small tray between two stations without requiring an external guide rail.
Dual-End Switch Tripping
The rear rod extension independently trips a CMSG or DMSG sensor at 225 mm, confirming stroke completion while the front rod drives the primary 79 N working load.
Is the Airtac MID Series Double Rod Mini Cylinder MID20X225S the Right Cylinder?
When sizing this double-rod unit, consider the adjacent bores: stepping down to the MID16X225S drops the 0.5 MPa force to 86.4 N, while moving up to the MID25X225S raises it to 206.1 N. The through-rod design is ideal for applications needing anti-rotation stability, a back-rod stop, or a twin-load drive. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot block is unavailable for this variant). For position feedback, the -S magnet pairs with CMSG, DMSG, or EMSG sensors.
Note that fixed TPU bumper pads only soften the stroke end; they do not lock the piston. If air pressure drops, the cylinder drifts, so use an external rod lock or pilot check valve to hold a suspended 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 MID20X225S FAQ
Because it is a double-rod cylinder with a rod on each side, the force is equal both ways: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a maximum theoretical output of 26.9 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. The stainless-steel through-rod resists mild corrosion and exits both ends, which prevents rotation and leaves the back rod free to trip a switch or carry a secondary stop.
