Airtac MID Series Double Rod Mini Cylinder MID20X200S
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID20X200S is a genuine double acting, double rod round-body mini air cylinder with a Ø20mm bore and 200mm 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 MID20X200S
Delivering 131.9 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 the Ø8 mm piston rod exits both end covers, the extend and retract forces are perfectly equal, and the rear rod end is free to trip a switch or carry a stop. The riveted stainless construction offers mild corrosion resistance for washdown environments.
It conforms to the ISO 6432 mounting interface for easy bracket integration and features a 1/8" port. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG switches. For sizing, the 131.9 N output at 0.5 MPa translates to a safe working load of about 79 N, or roughly 6.7 kg of vertical lift with a 2:1 margin.

Where the Airtac MID Series Double Rod Mini Cylinder MID20X200S Is Used
Symmetric Shuttle Pusher
Drives a lightweight part left and right with 131.9 N of equal force, using the twin rod to keep the pusher plate steady without external guides.
Back-Rod Switch Trip
Uses the rear protruding rod end to physically trip an external limit switch or flag, confirming stroke completion while the front rod performs the main work.
Guided Flap Deflector
Diverts light packaging flow on a conveyor, relying on the through-rod to resist torsional side load and maintain smooth operation in mildly humid conditions.
Is the Airtac MID Series Double Rod Mini Cylinder MID20X200S the Right Cylinder?
If you need less force, the smaller MID16 bore provides 86.4 N at 0.5 MPa; if your application requires more, stepping up to the MID25 yields 206.1 N. This 20 mm bore is a solid middle ground. The through-rod configuration is ideal when you need anti-rotation stability, a back-rod stop, or symmetric shuttle movements without an external guide.
Position holding is not inherent to this cylinder, as air loss will cause the piston to drift and the fixed TPU bumpers only soften the stroke end. Use an external rod lock or pilot check valve for suspended loads. You can mount via LB foot, FA flange, or TC trunnion (the SDB pivot block is unavailable here), and the -S magnet enables position sensing.
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 MID20X200S FAQ
Because it is a double-rod cylinder, the force is equal both ways: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a maximum of 26.9 kgf at 1.0 MPa. It uses a 1/8" port.
No, the piston will drift on air loss. The fixed TPU bumpers only decelerate the stroke end; they do not lock. For holding a suspended load, use an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors.
