Airtac MFD Double Rod Miniature Cylinder MFD20X80
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD20X80 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø20mm bore and 80mm 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 MFD20X80
Generating 131.9 N of thrust at 0.5 MPa in both directions, the AirTAC MFD20X80 is a double-acting, double-rod mini cylinder built to JIS standards. Its SUS304 stainless round body with riveted aluminium covers is shorter than an ISO 6432 unit of the same bore and stroke, saving valuable machine space while resisting mild washdown corrosion.
Because a rod exits both covers, the effective area is identical on extension and retraction, yielding equal force and natural anti-rotation stability. This 20 mm bore model uses an 8 mm rod with an M8x1.25 thread and a 1/8" port. It yields a safe working load of roughly 79 N (about 60% of the 0.5 MPa rating) and can vertically lift around 6.7 kg with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MFD Double Rod Miniature Cylinder MFD20X80 Is Used
Twin-Tool Transfer
Uses the 80 mm stroke to push and pull a part with equal 131.9 N force, mounting a secondary ejector on the opposing rod for synchronized handling.
Anti-Rotation Slide
Twin 8 mm rods steady the load across the 80 mm travel, cutting side-play and preventing twist on light precision guiding fixtures.
Compact Stopper Gate
Fits into tight JIS machinery envelopes shorter than ISO 6432 equivalents, using the back rod as a hard mechanical stop without needing sensors.
Is the Airtac MFD Double Rod Miniature Cylinder MFD20X80 the Right Cylinder?
When sizing this 20 mm bore against the larger MFD25, compare the real thrust: the MFD20X80 provides 131.9 N at 0.5 MPa, while the MFD25 offers 206.1 N. Choose the 20 mm bore for lighter guiding tasks where equal force both ways and a compact 80 mm stroke are required. The twin rods resist side-play and allow a second tool or stopper to mount on the back rod.
This non-magnet SKU cannot accept position switches, so specify an -S variant if you need CMSG, DMSG or EMSG sensing. Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover code exists). Fixed TPU bumper pads decelerate the stroke ends, but the cylinder will drift on air loss, so add an external rod lock or pilot check valve for held loads.
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 MFD20X80 FAQ
The MFD20X80 provides equal thrust both ways: 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. It features a 20 mm bore, an 8 mm rod, and a 1/8" air port.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSG, DMSG or EMSG sensors. The double-rod build provides equal force and anti-rotation but cannot hold position on air loss without an external rod lock.
