Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X250
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X250 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 250mm 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 MFCD Double Rod Cushioned Mini Cylinder MFCD25X250
Twin rods exit both covers on the MFCD25X250, yielding equal thrust in both directions while actively resisting load rotation. This JIS-standard round-body mini cylinder uses a SUS304 stainless barrel with riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke. A needle-set variable air cushion at each end decelerates the 250 mm travel smoothly.
Delivering 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa through its 1/8" port, the bore generates equal force both ways. This translates to a safe working load of about 124 N, or a vertical lift of roughly 10.5 kg with a 2:1 margin. Note this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without switching to the -S variant.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X250 Is Used
Dual-Tool Transfer
Pushes and retracts a dual-pick fixture over a 250 mm span, using the second rod to steady the 10.5 kg vertical load and prevent twist during rapid reversals.
High-Speed Forming Stop
Cycles a forming stop back and forth at speed, relying on the needle-set air cushions to softly absorb the 206.1 N impact without slamming the covers.
Guided Divert Gate
Actuates a heavy sorting flap where equal force both ways is needed; the twin rods keep the gate aligned despite off-center box impacts.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X250 the Right Cylinder?
When sizing this series, compare both directions: the MFCD20 provides 131.9 N at 0.5 MPa, while this MFCD25 hits 206.1 N. If your high-speed twin-tool setup needs more force, the MFCD32 offers 345.6 N. The adjustable air cushion is ideal for absorbing end-of-stroke shock, but remember it only decelerates the piston—it is not a brake. If air pressure drops, the load will drift; for secure holding, add an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover code exists since a rod exits both ends).
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 MFCD Double Rod Cushioned Mini Cylinder MFCD25X250 FAQ
Because it is a double-rod cylinder, force is equal both ways (rod-side area). It generates 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa, with a theoretical max of 42 kgf at 1.0 MPa. The air port size is 1/8".
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG switches. You must select the -S magnet variant for sensing. The twin-rod build provides anti-rotation, and the variable air cushions decelerate the load near stroke end, but they do not lock or hold position on air loss.
