Airtac MFD Double Rod Miniature Cylinder MFD40X160
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD40X160 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MFD40X160
Delivering 527.8 N of equal thrust in both directions at 0.5 MPa, the AirTAC MFD40X160 is a JIS-standard round-body mini cylinder built for non-rotating actuation. Its SUS304 stainless steel barrel and riveted aluminium covers shrug off mild corrosion and washdown environments. Because a piston rod exits both covers, you get identical push and pull forces on the rod-side area, while the twin rods steady the load and cut side-play versus a single-rod unit. This 40 mm bore, 160 mm stroke model uses a 1/4" port and M14x1.5 male rod threads, offering a shorter mounting length than a comparable ISO 6432 cylinder.
The fixed TPU bumper pads decelerate the stroke ends smoothly across the 30-800 mm/s speed range. As this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches. For sizing, this bore yields a safe working load of about 317 N (roughly 60% of the 0.5 MPa figure), which translates to a vertical lift capacity of approximately 26.9 kg with a 2:1 safety margin. Note that the cylinder drifts on air loss, so add an external rod lock or pilot check valve if you need to hold a load.

Where the Airtac MFD Double Rod Miniature Cylinder MFD40X160 Is Used
Twin-Tool Transfer
Mount a secondary gripper on the rear rod to execute a secondary task in reverse, utilising the 527.8 N equal thrust for synchronous part handling.
Anti-Rotation Slide
The dual 16 mm rods resist torsion under offset loads, guiding a 160 mm stroke machining fixture without the side-play of a single rod.
Dual-End Stopper
Use the protruding back rod as a hard mechanical stop or trigger flag for a pallet conveyor, taking advantage of the steady twin-rod guide.
Is the Airtac MFD Double Rod Miniature Cylinder MFD40X160 the Right Cylinder?
When choosing between the two largest MFD bores, the MFD32 provides 345.6 N at 0.5 MPa, while this MFD40X160 steps up to 527.8 N at 0.5 MPa (738.9 N at 0.7 MPa) for heavier slides. The double-rod design is essential when you need strict anti-rotation control, want to mount a second tool on the back rod, or require a mechanical stopper. Mounting options include LB foot, FA flange, and TC trunnion; there is no SDB or back-cover code because a rod exits both ends. If your application requires end-of-stroke sensing, you must select the -S magnet variant, as this standard SKU cannot host a sensor.
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 MFD40X160 FAQ
The MFD40X160 generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. Because it is a double-rod cylinder, this force is identical in both directions. The theoretical maximum is 107.6 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The twin rods provide anti-rotation, and fixed TPU bumpers decelerate the stroke ends.
