About the Airtac MID Series Double Rod Mini Cylinder MID20X10S
Delivering 131.9 N of thrust at 0.5 MPa in both directions, this AirTAC stainless steel round-body mini cylinder uses a through-rod design that ensures extend and retract forces remain identical. Because the Ø8 mm piston rod exits both end covers, the twin-rod construction naturally resists rotation and side loads, providing steadier guidance for light jobs without needing an external guide. The back rod end is free to trip a switch or carry a stop. Equipped with a built-in magnet (-S), it supports CMSG, DMSG, and EMSG sensors for position detection.
Built to the ISO 6432 mounting interface, this Ø20 mm bore drops directly into standard mini brackets and clevises. It features a 1/8" port and an M8x1.25 male rod thread. Operating at 30-800 mm/s, the stainless barrel and rod offer reliable mild corrosion and washdown resistance. For sizing, a safe working load is approximately 79 N (about 60% of the 0.5 MPa force), translating to a vertical lift capacity of roughly 6.7 kg with a 2:1 safety margin.

Where the Airtac MID Series Double Rod Mini Cylinder MID20X10S Is Used
Symmetric Shuttle Transfer
Pushing a light 6 kg jig back and forth between two stations, utilizing the equal 131.9 N force both ways for consistent cycle timing.
Back-Rod Switch Trip
Uses the rear protruding rod end to physically trigger an external limit switch, confirming stroke completion without needing extra space on the front face.
Guided Component Pressing
Steadily seats small electronic components where the twin through-rod prevents rotational twist during the 10 mm downstroke.
Is the Airtac MID Series Double Rod Mini Cylinder MID20X10S the Right Cylinder?
When sizing this 20 mm bore, step down to a MID16 (86.4 N @0.5 MPa) for lighter duties, or move up to a MID25 (206.1 N @0.5 MPa) if you need more power. The double-rod layout is specifically beneficial when your application demands anti-rotation stability, a back-rod switch trip, or symmetric shuttle movements. Keep in mind that the 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 brackets (the SDB pivot block is unavailable for this double-rod variant).
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 MID20X10S FAQ
Because it is a double-rod cylinder, force is equal both ways: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a maximum theoretical force of 26.9 kgf at 1.0 MPa. The air port is 1/8".
No, the piston will drift on air loss. The fixed TPU bumpers only decelerate the stroke end and do not act as a brake. You must use an external rod lock or pilot check valve to hold a suspended load. The -S magnet enables position sensing with CMSG/DMSG/EMSG switches.
