Airtac MFD Double Rod Miniature Cylinder MFD32X40
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD32X40 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MFD32X40
Twin rods exiting both covers define the AirTAC MFD32X40, yielding identical thrust in extend and retract directions. As a JIS-standard round-body mini cylinder, it uses a SUS304 stainless barrel with riveted aluminium covers to resist mild corrosion and washdown. This 32mm bore generates 345.6N at 0.5MPa and 483.8N at 0.7MPa, with a theoretical maximum of 70.5kgf at 1.0MPa. The 1/4" port feeds the chamber, while fixed TPU bumper pads decelerate the stroke ends.
The dual-rod geometry steadies the payload and resists rotation better than a single-rod build, and the rear rod offers a ready mount for a stopper or secondary tool. For this bore, a safe working load is roughly 207N (about 60% of the 0.5MPa figure), translating to a vertical lift capacity of about 17.6kg with a 2:1 margin. This base SKU lacks a magnet and cannot accept position switches; adding the -S option enables CMSG, DMSG, or EMSG sensors. Note that a plain cylinder drifts on air loss, so use an external rod lock or pilot check valve if you must hold a load.

Where the Airtac MFD Double Rod Miniature Cylinder MFD32X40 Is Used
Anti-Rotation Slides
The twin rods resist side-play and twisting, guiding 345.6N payloads smoothly without the rotation drift common to single-rod minis.
Twin-Tool Actuation
Mount a secondary clamp or stopper on the rear rod to operate a second station simultaneously with equal extending and retracting force.
Washdown Diverters
The SUS304 stainless barrel withstands mild washdown environments while pushing diverters with a safe working load of about 207N.
Is the Airtac MFD Double Rod Miniature Cylinder MFD32X40 the Right Cylinder?
Choosing between the available bores means sizing both directions: the MFD25 provides 206.1N at 0.5MPa, this MFD32X40 delivers 345.6N, and the MFD40 offers 527.8N. Select the 32mm bore when your payload requires that mid-range thrust and you need the anti-rotation stability of two rods or want to mount a second tool on the back rod. Because a rod exits both ends, there is no back-cover code and no SDB mount; use LB foot, FA flange, or TC trunnion brackets. Remember that this non-magnet SKU cannot take a sensor, and the fixed TPU bumpers only decelerate the stroke end—they do not lock the load on air loss.
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 MFD32X40 FAQ
The MFD32X40 is a double-acting, double-rod cylinder with a 1/4" air port. Because the rod exits both covers, thrust is equal in both directions: 345.6N at 0.5MPa, 483.8N at 0.7MPa, and a theoretical maximum of 70.5kgf at 1.0MPa.
This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensing. Additionally, the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake, so the piston will drift on air loss unless you use an external rod lock or pilot check valve.
