Airtac MID Series Double Rod Mini Cylinder MID20X160
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID20X160 is a genuine double acting, double rod round-body mini air cylinder with a Ø20mm bore and 160mm 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 MID20X160
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, making it ideal for guiding light loads without an external guide rail. The rear rod end remains free to trip a switch or carry a stop. Built with a stainless barrel and rod, it handles mild washdown environments and conforms to the ISO 6432 mounting interface for standard mini brackets.
This double-acting unit features a 160 mm stroke, a 1/8" port, and M8x1.25 male rod threads. Operating at 30-800 mm/s, it provides a safe working load of about 79 N (roughly 60% of the 0.5 MPa figure) and can vertically lift around 6.7 kg with a 2:1 safety margin. Fixed TPU bumper pads decelerate the stroke ends. Note that this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors; you must specify the -S option for position sensing.

Where the Airtac MID Series Double Rod Mini Cylinder MID20X160 Is Used
Symmetric Shuttle Transfer
Moves lightweight trays back and forth with equal 131.9 N force in both directions, using the through-rod to maintain stable tracking without twisting.
Back-Rod Flag Trigger
Uses the protruding rear rod end to physically trip a mechanical limit switch or carry a visual position flag, saving space on the front working end.
Guided Push Assembly
Presses small components with a steady 79 N safe working load, relying on the twin-rod anti-rotation properties to keep the tooling perfectly aligned.
Is the Airtac MID Series Double Rod Mini Cylinder MID20X160 the Right Cylinder?
If your application requires less force, the MID16 bore provides 86.4 N at 0.5 MPa, while stepping up to the MID25 yields 206.1 N for heavier pushes. Choose this Ø20 model when you need symmetric force for a shuttle mechanism or when the back rod must drive a second load. The twin-rod construction inherently resists torsion, keeping guiding steady.
Keep in mind that the fixed bumper pads only soften the end of stroke; they do not lock the piston. If air pressure drops, the cylinder will drift, so add an external rod lock or pilot check valve for suspended loads. For mounting, use LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is not compatible with this double-rod variant). Because this SKU has no magnet, order an -S variant if you need switch readiness.
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 MID20X160 FAQ
Because the double-rod design has a rod on both sides, 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. It uses a 1/8" port.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG sensors. You would need the -S variant for switch readiness. The stainless steel build and twin-rod design still provide excellent mild corrosion resistance and anti-rotation stability.
