Airtac MID Series Double Rod Mini Cylinder MID20X75
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID20X75 is a genuine double acting, double rod round-body mini air cylinder with a Ø20mm bore and 75mm 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 MID20X75
Delivering 131.9 N of thrust at 0.5 MPa in both directions, this AirTAC round-body mini cylinder uses a through-rod design so extend and retract forces are perfectly equal. The twin rod resists rotation and side loads, providing steady guidance without an external rail. Its stainless-steel barrel and rod shrug off mild corrosion and washdown environments.
Built to the ISO 6432 mounting interface, the Ø20 bore drops directly into standard mini brackets and clevises. It features a 1/8" port and an M8x1.25 male rod thread. For sizing, this bore yields a safe working load of about 79 N (60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 6.7 kg with a 2:1 safety margin. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors.

Theoretical Output Force (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 132 N |

Where the Airtac MID Series Double Rod Mini Cylinder MID20X75 Is Used
Symmetric Shuttle Transfer
Moves lightweight trays back and forth using equal 131.9 N force, with the twin rod preventing twist during rapid reversals.
Back-Rod Switch Trip
The rear rod extension mechanically trips an external limit switch to confirm position without needing a cylinder magnet.
Guided Push Assembly
Presses small components with steady anti-rotation support, handling a safe working load of 79 N without an external guide rail.
Is the Airtac MID Series Double Rod Mini Cylinder MID20X75 the Right Cylinder?
If 131.9 N at 0.5 MPa is too much, step down to the MID16 (86.4 N); if you need more push and pull, the MID25 offers 206.1 N. The through-rod is ideal when you need anti-rotation stability, want to trip a switch from the back rod end, or must drive a second load simultaneously.
Remember that fixed TPU bumper pads only soften the stroke end; they do not lock the piston. If air pressure drops, the cylinder drifts, so fit an external rod lock or pilot check valve for held loads. For mounting, choose LB foot, FA flange or TC trunnion (the SDB pivot block is unavailable here). Add the -S option if you require 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 MID20X75 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, this specific SKU does not include a magnet, so CMSG, DMSG and EMSG sensors will not function. You must order the -S variant to enable sensing. The stainless-steel build resists mild corrosion.
