About the Airtac MID Series Double Rod Mini Cylinder MID20X160S
Delivering 131.9 N of equal thrust in both directions, this AirTAC MID20X160S is a double-acting, through-rod mini cylinder built for balanced actuation. The twin rod design resists side loads and rotation without needing an external guide, while the rear rod end is free to trip a switch or carry a stop. Its stainless steel round barrel and rod withstand mild washdowns, and it drops directly into ISO 6432 standard mini brackets.
Fitted with a 1/8" port and an M8x1.25 male rod thread, this 20 mm bore unit travels 160 mm at speeds of 30-800 mm/s. The built-in magnet (-S) supports CMSG, DMSG, or EMSG switches for position sensing. Based on the 0.5 MPa rating, it handles a safe working load of roughly 79 N, moving about 6.7 kg vertically each way with a 2:1 margin.

Where the Airtac MID Series Double Rod Mini Cylinder MID20X160S Is Used
Guided Push Mechanism
With 131.9 N of equal force both ways, the twin rod prevents twisting during horizontal pushing of light jigs or parts.
Rear Rod Switch Trip
The extended back rod travels 160 mm to physically trigger an external limit switch or flag without extra linkages.
Symmetric Shuttle
Move a 6.7 kg payload back and forth smoothly, using the equal double-rod thrust to maintain stable bidirectional transfer.
Is the Airtac MID Series Double Rod Mini Cylinder MID20X160S the Right Cylinder?
If your application requires less force, the MID16 bore provides 86.4 N at 0.5 MPa; stepping up to the MID25 yields 206.1 N. The through-rod configuration is ideal when you need anti-rotation stability, a back-rod mechanical stop, or symmetric shuttle movements. Position sensing is enabled by the internal magnet for CMSG/DMSG/EMSG switches.
Mount using LB foot, FA flange, or TC trunnion brackets, noting the SDB pivot block is not offered on this double-rod variant. Fixed TPU bumpers decelerate the stroke ends but do not lock the piston; if air pressure drops, the cylinder will drift. Use an external rod lock or pilot check valve to hold a suspended load safely.
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 MID20X160S FAQ
It provides equal force both ways: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a maximum theoretical 26.9 kgf at 1.0 MPa. The air port is 1/8".
No, fixed TPU bumpers only soften the stroke end and do not lock the piston. The internal -S magnet enables position sensing, but an external rod lock is required to hold loads.
