Airtac MFD Double Rod Miniature Cylinder MFD25X200S
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD25X200S is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø25mm bore and 200mm 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 MFD25X200S
Twin piston rods exit both covers of this JIS-standard round-body mini cylinder, yielding identical thrust in extend and retract directions while steadying the load against rotation. The SUS304 stainless barrel and riveted aluminium covers form a compact body that is shorter than an ISO 6432 unit for the same 25 mm bore and 200 mm stroke. Equipped with a built-in magnet (-S), it accepts CMSG, DMSG or EMSG switches for position sensing.
At 0.5 MPa the rod-side area generates 206.1 N of force both ways, rising to 288.5 N at 0.7 MPa, with a theoretical maximum of 42 kgf at 1.0 MPa. For a reliable setup, figure on a safe working load around 124 N (about 60 percent of the 0.5 MPa figure) or a vertical lift of roughly 10.5 kg with a 2:1 margin. Air connects via 1/8" ports, and fixed TPU bumper pads absorb end-of-stroke impacts across the 30-800 mm/s speed range.

Where the Airtac MFD Double Rod Miniature Cylinder MFD25X200S Is Used
Anti-Rotation Transfer Slide
Moves a 200 mm stroke clamping fixture without twisting, using the twin rods to resist side-play while applying 206.1 N of equal thrust both ways.
Twin-Tool Actuation
Drives a primary workhead on the front rod and mounts a secondary stopper or return flag on the rear rod, maximising the 25 mm bore output.
Magnet-Enabled Sorting Gate
Uses the built-in -S magnet with DMSG switches to confirm gate position over 200 mm, handling roughly 10.5 kg vertical loads with a 2:1 safety margin.
Is the Airtac MFD Double Rod Miniature Cylinder MFD25X200S the Right Cylinder?
Choose between the two available bores by comparing the 0.5 MPa output: the MFD20 delivers 131.9 N both ways, whereas this MFD25 provides 206.1 N for heavier slides. The twin-rod architecture is ideal when you need strict anti-rotation resistance, want to mount a second tool on the back rod, or require a cam for a sensor flag. Remember that the -S suffix on this SKU enables CMSG, DMSG and EMSG switches; a plain SKU without S cannot take a sensor.
Mounting options include LB foot, FA flange and TC trunnion (there is no SDB or back-cover code because a rod exits both ends). Note that fixed TPU bumpers only decelerate the stroke end—they do not lock the piston. If your application must hold a vertical load on air loss, add an external rod lock or pilot-operated check valve.
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 MFD25X200S FAQ
It generates equal force in both directions: 206.1 N at 0.5 MPa, 288.5 N at 0.7 MPa, and a theoretical max of 42 kgf at 1.0 MPa. Air connects via 1/8" ports, and the male rod thread is M10x1.25.
The twin rods provide strict anti-rotation guidance and equal thrust both ways. The -S suffix means it has a magnet for CMSG/DMSG/EMSG sensors. It does not hold load on air loss—fixed TPU bumpers only decelerate; use an external rod lock for holding.
