Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X25
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X25 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm 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 MFCD20X25
Needle-set air cushions at both ends distinguish this MFCD20X25 mini cylinder, soaking up high-speed end-of-stroke shock while twin rods exit both covers to resist rotation. As a JIS-standard round-body unit built with a SUS304 stainless barrel and riveted aluminium covers, it delivers equal force both ways and measures shorter than an ISO 6432 cylinder for the same bore and stroke.
Operating at 30-800 mm/s, the 20 mm bore generates 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa through its 1/8" port, yielding a safe working load of roughly 79 N or a 6.7 kg vertical lift with a 2:1 margin. This non-magnet SKU cannot host position sensors; adding the -S option enables CMSG, DMSG or EMSG switches. Note that the cushion only decelerates the load and does not function as a brake.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X25 Is Used
Twin-Tool Transfer
Shifts small parts between stations using dual rods for anti-rotation stability, handling a safe working load of 79 N at high cycle rates.
Gripper Actuation
Drives synchronized grippers where equal force both ways ensures balanced clamping, with air cushions absorbing rapid reversals.
Component Ejection
Ejects light molded parts from a press bed, using the second rod to mount a stopper while the cushion softens the stroke end.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X25 the Right Cylinder?
When sizing these double-acting cylinders, compare the 131.9 N @0.5 MPa output of this 20 mm bore against the 206.1 N @0.5 MPa capacity of the MFCD25 to match your load. The adjustable air cushion and twin rods are ideal for high-speed anti-rotation tasks or shock-sensitive twin-tool setups. Because a plain cylinder drifts on air loss, integrate an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange or TC trunnion (no SDB), and remember this specific SKU lacks a magnet for sensing.
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 MFCD20X25 FAQ
It delivers equal force both ways via a 1/8" port: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical max of 26.9 kgf at 1.0 MPa.
This specific SKU has no magnet and cannot take a switch; selecting the -S variant enables CMSG, DMSG or EMSG sensors. The twin-rod build with variable air cushions provides smooth, anti-rotation motion without bumpers.
