About the Airtac MID Series Double Rod Mini Cylinder MID16X20S
Delivering 86.4 N of thrust at 0.5 MPa in both directions, this AirTAC MID16X20S is a stainless-steel, round-body mini cylinder built for double-acting operation. Because a Ø6 mm piston rod exits both end covers, the extend and retract areas are identical, ensuring equal force while naturally resisting rotation and side loads without an external guide. The -S suffix denotes a built-in piston magnet, allowing seamless integration with CMSG, DMSG, or EMSG switches for position sensing.
The riveted stainless construction provides reliable mild corrosion and washdown resistance. It uses a 1/8" port and conforms to the ISO 6432 mounting interface for straightforward bracket integration. For application sizing, a safe working load is approximately 52 N (60% of the 0.5 MPa force), which translates to a vertical lift capacity of about 4.4 kg when applying a 2:1 safety margin. Fixed TPU bumper pads soften the stroke endpoints, operating at speeds from 30 to 800 mm/s across a -20 to +70 C temperature range.

Where the Airtac MID Series Double Rod Mini Cylinder MID16X20S Is Used
Symmetric Shuttle Transfer
With 86.4 N of equal force both ways, this cylinder smoothly pushes a lightweight shuttle back and forth, using the twin rod to keep the carriage aligned without external guides.
Back-Rod Switch Tripping
The extended rear rod provides a convenient mounting point to physically trip a limit switch or flag at 20 mm stroke, confirming retraction without consuming extra workspace.
Guided Push Assembly
Ideal for pressing small electronic components where the anti-rotation property of the double rod ensures the tool face stays perfectly perpendicular during the 4.4 kg guided push.
Is the Airtac MID Series Double Rod Mini Cylinder MID16X20S the Right Cylinder?
When sizing this 16 mm bore, stepping down to a MID12X20S reduces the equal both-ways force to 42.4 N at 0.5 MPa, whereas stepping up to a MID20X20S increases it to 131.9 N. Choose this model when your mechanism requires anti-rotation stability, needs the back rod end to trip a switch or carry a stop, or must drive two loads simultaneously. The -S magnet enables CMSG, DMSG, and EMSG sensors, and you can mount via LB foot, FA flange, or TC trunnion (the SDB pivot block is unavailable for double-rod types).
Keep in mind that a standard cylinder does not hold position upon air loss; the piston will drift, and the fixed TPU bumpers only decelerate the stroke end rather than locking the load. If your application requires maintained position under pressure loss, incorporate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 MID16X20S FAQ
Because it is a double-rod cylinder, the force is equal both ways: 86.4 N at 0.5 MPa, 120.9 N at 0.7 MPa, and a maximum theoretical output of 17.6 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 near the stroke end; they do not lock the load. You must use an external rod lock or pilot check valve for holding. The -S magnet works with CMSG/DMSG/EMSG sensors.
