Airtac MFD Double Rod Miniature Cylinder MFD40X150
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD40X150 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MFD40X150
Generating 527.8 N of thrust at 0.5 MPa in both directions, the AirTAC MFD40X150 is a double-acting, double-rod mini cylinder built to JIS standards. Because a piston rod exits both the front and rear aluminium covers, the output force remains identical on extension and retraction. The SUS304 stainless steel barrel is riveted into a round-body construction that is shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable machine footprint while resisting mild corrosion.
The twin Ø16 mm rods steady the payload and significantly reduce side-play compared to a single-rod build, making it ideal for anti-rotation slides. This specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors; adding the -S variant enables that capability. With fixed TPU bumper pads decelerating the stroke ends at speeds of 30-800 mm/s, it handles a safe working load of about 317 N. Note that the bumper is not a brake, so an external rod lock or pilot check valve is required to hold a vertical load on air loss. Air connects via 1/4" ports.

Where the Airtac MFD Double Rod Miniature Cylinder MFD40X150 Is Used
Twin-Tool Transfer
Drives a 150 mm stroke transfer unit where a second tool mounts directly to the rear rod, utilizing the equal 527.8 N force for synchronized part handling.
Anti-Rotation Lift
Raises and lowers a 25 kg guided payload without twisting, using the rigid twin-rod guide to maintain strict alignment through the 150 mm travel.
Dual-End Sorting
Actuates a sorting diverter on a packaging line, using the back rod to trigger a mechanical flag while the front rod pushes the product.
Is the Airtac MFD Double Rod Miniature Cylinder MFD40X150 the Right Cylinder?
When sizing an MFD, you have four bores available. This 40 mm bore delivers 527.8 N at 0.5 MPa, offering a substantial step up from the 345.6 N provided by the MFD32. If your application demands equal force both ways, twin-tool actuation, or resistance to rotation, the double-rod design is the correct choice over the single-rod MF series. For vertical lifts, expect it to handle about 26.9 kg safely with a 2:1 margin.
Mounting options include LB foot, FA flange, and TC trunnion brackets; there is no SDB or back-cover code because a rod exits the rear. Remember that this non-magnetic SKU cannot support position sensing. If you need end-of-stroke signals, specify the -S magnet version to use CMSG, DMSG, or EMSG switches.
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 MFD40X150 FAQ
The MFD40X150 provides equal thrust in both directions because it uses the rod-side area on both strokes. It generates 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical maximum of 107.6 kgf at 1.0 MPa. The air port size for this 40 mm bore is 1/4".
No to both. The fixed TPU bumper pads only decelerate the stroke end and do not act as a lock; the piston will drift on air loss, so you need an external rod lock or pilot check valve for holding. Additionally, this SKU has no magnet, so it cannot take CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.
