Airtac MFD Double Rod Miniature Cylinder MFD20X150
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD20X150 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø20mm bore and 150mm 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 MFD20X150
Twin rods exiting both covers define this JIS-standard round-body mini cylinder, ensuring output force remains identical in extend and retract motions. For the 20 mm bore, this means 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa each way, driven through a 1/8 inch port. The SUS304 stainless barrel shrinks overall length compared to an ISO 6432 unit of the same stroke.
With a 150 mm stroke, the fixed TPU bumper pads absorb end-of-travel impacts without acting as a lock. This non-magnet SKU cannot host position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches on the rear rod. A practical safe working load is roughly 79 N, or about 6.7 kg of vertical lift with a 2:1 margin.

Where the Airtac MFD Double Rod Miniature Cylinder MFD20X150 Is Used
Anti-Rotation Slides
The dual 8 mm rods steady the payload across the 150 mm travel, preventing the twist that single-rod minis suffer under offset loads.
Twin-Tool Actuation
Mount a stopper or secondary mechanism on the opposing rod end to perform two synchronized tasks within the 131.9 N thrust envelope.
Transfer Pushers
Equal force both ways makes this cylinder suited for pushing parts back and forth on a line, handling roughly 6.7 kg vertically per direction.
Is the Airtac MFD Double Rod Miniature Cylinder MFD20X150 the Right Cylinder?
Choosing between the two available bores comes down to thrust: this 20 mm version yields 131.9 N at 0.5 MPa, while the 25 mm variant pushes 206.1 N. The double-rod layout is ideal when you need anti-rotation stability or want to mount a secondary tool on the back side. Note that a plain cylinder drifts on air loss, so fit an external rod lock or pilot check valve if the load must be held.
Mounting options include LB foot, FA flange, and TC trunnion brackets; there is no SDB or back-cover code because a rod exits both ends. Because this specific SKU lacks a magnet, it cannot accept magnetic switches—select an -S model if sensing is required.
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 MFD20X150 FAQ
Force is equal in both directions due to the double-rod design. It generates 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical maximum of 26.9 kgf at 1.0 MPa. The air port is 1/8 inch.
The twin rods inherently resist rotation and provide steadier guidance than a single rod. However, this specific SKU has no magnet and cannot take a sensor; you need the -S version to use CMSG, DMSG, or EMSG switches.
