Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X80S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X80S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø25mm 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 MFCD Double Rod Cushioned Mini Cylinder MFCD25X80S
Twin rods exit both covers on this 25 mm bore JIS-standard round-body mini cylinder, yielding equal 206.1 N force at 0.5 MPa in both 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 stroke, saving valuable machine space. A needle-set variable air cushion at each end soaks up high-speed end-of-stroke shock for quiet motion.
With an 80 mm stroke and a built-in piston magnet (-S), this model accepts CMSG, DMSG or EMSG switches for position sensing. The 1/8" air port and M10x1.25 male rod threads simplify integration. Based on the 0.5 MPa rating, expect a safe working load around 124 N, or a vertical lift of roughly 10.5 kg with a 2:1 margin. Remember that the cushion only decelerates the load near stroke end; it does not function as a brake.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X80S Is Used
Twin-Tool Transfer
Drive a 10.5 kg vertical pick-and-place with equal force both ways, using the second rod to mount a parallel gripper for synchronized part handling.
Anti-Rotation Indexing
Prevent side-play on a high-speed 80 mm stroke by locking the load between twin rods, absorbing end-stop shock via the variable air cushion.
Washdown Guiding
Push and pull a 124 N machining fixture in a mildly corrosive environment, relying on the SUS304 stainless barrel for durable performance.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X80S the Right Cylinder?
When sizing this JIS-standard family, compare the real thrust: the MFCD20 provides 131.9 N at 0.5 MPa, whereas this MFCD25 hits 206.1 N both ways. Choose the 25 mm bore when moving heavier jigs or resisting higher torque. The double-rod architecture is essential for high-speed anti-rotation tasks or mounting twin tools, and the adjustable air cushion handles rapid 30-800 mm/s cycles. Because a rod exits both covers, there is no back-cover code or SDB mount; use LB foot, FA flange or TC trunnion brackets.
This MFCD25X80S variant includes the -S magnet for CMSG/DMSG/EMSG sensors. If your pneumatic circuit drops pressure, the piston will drift; the air cushion only decelerates impact and cannot hold position. Specify an external rod lock or pilot check valve if you need strict load holding on air loss.
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 MFCD25X80S FAQ
Force is equal both ways due to the double-rod design. It generates 206.1 N at 0.5 MPa, 288.5 N at 0.7 MPa, and a theoretical maximum of 42 kgf at 1.0 MPa. The bore features a 1/8" port and M10x1.25 rod threads.
No. The needle-set variable air cushion at both ends only decelerates the piston near the stroke end to reduce shock; it is not a brake. For load holding on air loss, use an external rod lock. The -S magnet on this model supports CMSG/DMSG/EMSG sensors.
