Airtac MFD Double Rod Miniature Cylinder MFD32X225
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD32X225 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø32mm bore and 225mm stroke, 1/4" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MFD Double Rod Miniature Cylinder MFD32X225
Twin rods exiting both covers define the AirTAC MFD32X225, a double-acting JIS-standard round-body mini cylinder that delivers equal force in both directions. The SUS304 stainless barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke, while resisting mild washdown corrosion. At this 32 mm bore, the rod-side area generates 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa.
The second piston rod steadies the load and resists rotation far better than a single-rod mini. Because the rod-side area drives both faces, push and pull forces are identical. For practical sizing, a safe working load is roughly 207 N, or a vertical lift of about 17.6 kg with a 2:1 margin. Air connects via 1/4" ports, and fixed TPU bumper pads decelerate the stroke ends. Note that this SKU lacks a magnet, so it cannot take CMSG, DMSG or EMSG switches without specifying the -S option.

Where the Airtac MFD Double Rod Miniature Cylinder MFD32X225 Is Used
Twin-Tool Transfer
Drives a 225 mm stroke transfer carriage with tools mounted on both rod ends, utilising the 345.6 N equal force for synchronized part handling without rotation.
Anti-Rotation Stopper
The dual 12 mm rods resist side-play and twisting, providing a steady 483.8 N at 0.7 MPa to halt moving pallets securely along a conveyor line.
Back-Rod Actuation
Uses the rear rod extension to trip a mechanical limit switch or operate a secondary latch, taking advantage of the equal both-ways thrust up to 70.5 kgf.
Is the Airtac MFD Double Rod Miniature Cylinder MFD32X225 the Right Cylinder?
When choosing between the available bores, the MFD32X225 sits neatly in the middle of the range. The smaller MFD25 provides 206.1 N at 0.5 MPa, which may be insufficient for a 225 mm stroke carrying side loads, whereas the larger MFD40 yields 527.8 N at 0.5 MPa if you need extra thrust. The 32 mm bore offers a balanced 345.6 N at 0.5 MPa, making it ideal for medium-duty transfer tasks.
Select a double-rod build when you need anti-rotation stability, a twin-tool actuator, or a back-rod switching flag. Mounting options include LB foot, FA flange and TC trunnion; there is no SDB or back-cover code because a rod exits both ends. Remember that fixed TPU bumpers only decelerate the stroke end, they do not lock the piston. If air pressure drops, the load will drift, so fit an external rod lock or pilot check valve for position holding. Finally, this specific SKU has no magnet, so it cannot support sensors unless upgraded to an -S variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/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/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MFD Double Rod Miniature Cylinder MFD32X225 FAQ
The MFD32X225 features a 32 mm bore and 1/4" air ports. Because it is a double-rod cylinder using the rod-side area, force is equal both ways: 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a theoretical maximum of 70.5 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant to enable magnetic sensing. The twin-rod design still provides excellent anti-rotation guidance and equal force in both directions.
