About the Airtac MID Series Double Rod Mini Cylinder MID32X300S
Delivering 345.6 N of thrust at 0.5 MPa in both directions, this stainless steel round-body mini cylinder uses a through-rod design to balance extend and retract forces. Because a Ø12 mm rod exits both end covers, the working area is identical on each side, completely eliminating the push-pull force differential found in single-rod units. The twin-rod construction also resists rotation and side load, providing steadier guiding for lighter jobs without an external guide rail.
Built with a riveted stainless barrel and rod, the unit shrugs off mild corrosion and washdown environments. It features a 1/4" port, male M10x1.25 rod threads, and operates at 30-800 mm/s. With a safe working load around 207 N (roughly 60% of the 0.5 MPa figure), it can vertically lift about 17.6 kg with a 2:1 margin. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac MID Series Double Rod Mini Cylinder MID32X300S Is Used
Symmetric Shuttle Transfer
With 345.6 N of equal force both ways, this cylinder smoothly drives a 300 mm parts shuttle back and forth without the speed or force variance typical of single-rod units.
Back-Rod Switch Trip
The extended rear rod provides a convenient mounting point to physically trip a limit switch or carry a position flag, keeping the front workspace clear of sensors.
Guided Product Pusher
The twin Ø12 mm rods resist torsional twist and side loading, allowing the cylinder to push packages steadily along a conveyor without needing an external guide rail.
Is the Airtac MID Series Double Rod Mini Cylinder MID32X300S the Right Cylinder?
When sizing this 32 mm bore, step down to a MID25 (206.1 N at 0.5 MPa) for lighter duties, or step up to a MID40 (527.8 N at 0.5 MPa) if you need more muscle. The double-rod layout is ideal when you need anti-rotation stability, want to trip a switch from the back rod end, or need to drive a second load simultaneously. For mounting, choose LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers; note the SDB pivot-block is not offered on this variant.
Keep in mind the fixed TPU bumper pads only soften the stroke end and do not function as a lock. If air pressure drops, the piston will drift and cannot hold a load. To maintain position on air loss, install an external rod lock or a pilot-operated check valve.
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 MID32X300S FAQ
Because the double-rod design occupies both sides of the piston, force is equal both ways. It delivers 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a maximum theoretical force of 70.5 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. However, it does not hold position on air loss; the piston drifts and the fixed TPU bumpers only decelerate the stroke end. Use an external rod lock for holding.
