Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X25S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X25S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 25mm 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 MFCD25X25S
Twin rods exit both covers of this JIS-standard round-body mini cylinder, yielding equal 206.1 N force at 0.5 MPa in both directions while actively resisting side-play. The SUS304 stainless barrel and riveted aluminium covers form a compact body that is physically shorter than an ISO 6432 cylinder for the same 25 mm bore and 25 mm stroke, saving valuable machine space. A needle-set variable air cushion at each end absorbs end-of-stroke shock, allowing smooth high-speed motion up to 800 mm/s.
The integrated -S piston magnet supports CMSG, DMSG, and EMSG switches for position sensing. With a 1/8" port and M10x1.25 male rod threads, it delivers a safe working load of roughly 124 N (about 60% of the 0.5 MPa figure), or a 2:1 margin vertical lift of 10.5 kg each way. Remember the cushion only decelerates the load; it does not lock or hold position on air loss.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X25S Is Used
Twin-Tool Transfer
Uses the 206.1 N equal both-ways force to push and pull a lightweight gripper between stations at high speed without rotational drift.
Short-Stroke Spot Weld
The 25 mm stroke and needle-set air cushion decelerate the 10.5 kg vertical tool load smoothly, preventing impact marks at the weld tip.
Dual-End Diverter
Mounts a stopper flag on the back rod to actuate a second lane, leveraging the compact JIS body to fit inside tight conveyor frames.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X25S the Right Cylinder?
When sizing this series, compare both directions: this MFCD25 delivers 206.1 N at 0.5 MPa, whereas the smaller MFCD20 provides 131.9 N, and the larger MFCD32 offers 345.6 N. Choose the 25 mm bore when your application needs moderate push and pull forces with high-speed anti-rotation stability. The twin rods steady the load and allow mounting a second tool or stopper on the back side.
Because the cushion only decelerates near the stroke end and the piston drifts on air loss, add an external rod lock or pilot check valve if you must hold a vertical load. Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover code exists since rods extend from both ends). The -S magnet enables CMSG, DMSG, and EMSG sensors; a SKU without S cannot take a switch.
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 MFCD25X25S FAQ
It generates 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa in both directions, with a theoretical max of 42 kgf at 1.0 MPa. The fluid port is 1/8". Force is equal both ways because the double-rod design uses the same rod-side area for push and pull.
No, the variable air cushion only decelerates the piston near the stroke end; it is not a brake and the piston will drift on air loss. Use an external rod lock or pilot check valve to hold loads. The -S suffix means it has a built-in magnet for CMSG, DMSG, and EMSG switches.
