Airtac MFD Double Rod Miniature Cylinder MFD20X15
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD20X15 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø20mm bore and 15mm stroke, 1/8" 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 MFD20X15
Twin rods exiting both covers give the AirTAC MFD20X15 identical thrust in extend and retract, using a 20 mm bore with a compact 15 mm stroke. As a JIS-standard round-body mini cylinder, it features a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting length than an ISO 6432 unit of the same size. The twin-rod geometry steadies the payload and resists rotation far better than a single-rod build.
Delivering 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa through its 1/8" port, this double-acting cylinder yields a safe working load of roughly 79 N. It handles about 6.7 kg vertically each way with a 2:1 margin. Fixed TPU bumper pads absorb end-of-stroke impacts across the 30-800 mm/s speed range. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MFD Double Rod Miniature Cylinder MFD20X15 Is Used
Anti-Rotation Slides
The dual 8 mm rods resist twist during short 15 mm shifts, keeping precision slides aligned without side-play under a 79 N safe working load.
Twin-Tool Actuation
Mount a secondary tool or stopper on the rear rod to synchronise actions in both directions, leveraging the equal 131.9 N thrust at 0.5 MPa.
Compact Ejectors
Fits tight machinery where shorter than ISO 6432 length is vital, delivering rapid 30-800 mm/s ejection without rotational drift.
Is the Airtac MFD Double Rod Miniature Cylinder MFD20X15 the Right Cylinder?
Choosing between the two available bores comes down to payload: the MFD20 provides 131.9 N at 0.5 MPa, while stepping up to the MFD25 yields 206.1 N. For this 20 mm bore, the twin rods are ideal when you need to prevent a load from twisting or when mounting a secondary stopper on the back rod. You can fit LB foot, FA flange or TC trunnion mounts, but there is no SDB or back-cover option because a rod exits both ends.
Because this is a non-magnetised SKU without the -S option, it cannot accept position sensors. Furthermore, the fixed TPU bumpers only decelerate the stroke end; they do not act as a brake. If your setup must hold a vertical load during air loss, add an external rod lock or a pilot-operated check valve to prevent drift.
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 MFD20X15 FAQ
It generates equal force in both directions because it is a double-rod cylinder: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical max of 26.9 kgf at 1.0 MPa. The air port is 1/8".
This SKU lacks the -S magnet, so it cannot take CMSG, DMSG or EMSG switches. Also, the fixed TPU bumpers only decelerate the stroke; they do not lock the piston. Use an external rod lock or pilot check valve to hold loads on air loss.
