Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X300S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X300S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 300mm 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 MFCD20X300S
Needle-set air cushions at both ends define this MFCD20X300S mini cylinder, soaking up high-speed shock while delivering an equal 131.9 N force in both directions at 0.5 MPa. As a JIS-standard round-body unit, its SUS304 stainless barrel and riveted aluminium covers form a shorter envelope than an ISO 6432 cylinder for the same 20 mm bore and 300 mm stroke, saving valuable mounting length.
The twin 8 mm rods exit both covers to steady the load and resist rotation, while the built-in magnet (-S) supports CMSG, DMSG or EMSG switches for end-of-stroke sensing. With a 1/8" port and M8x1.25 male rod threads, it handles a safe working load of roughly 79 N or lifts about 6.7 kg vertically each way with a 2:1 margin.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X300S Is Used
Long-Reach Transfer
Uses the full 300 mm stroke to shift light electronic trays between conveyor belts, relying on the twin rods to keep the 131.9 N motion perfectly straight and twist-free.
Twin-Tool Actuation
Mounts a secondary stopper or gripper on the back rod while the front rod drives a high-speed pick-and-place head, with air cushions absorbing the end-of-stroke shock.
Guided Vertical Drop
Lowers a 6 kg assembly fixture smoothly at speed, using the equal both-ways force and needle-set cushions to prevent slamming at the bottom of the 300 mm travel.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X300S the Right Cylinder?
When sizing this 20 mm bore against the MFCD25, compare the real outputs: 131.9 N versus 206.1 N at 0.5 MPa. Choose the MFCD20 for lighter, high-speed anti-rotation tasks where twin rods prevent side-play, and step up to the 25 mm bore if your shock-sensitive twin-tool setup needs extra thrust. Both options run at 30-800 mm/s.
For mounting, select LB foot, FA flange or TC trunnion brackets (there is no SDB mount since a rod exits both covers). Remember that the variable air cushion only decelerates the piston near stroke end—it is not a lock. If your application must hold a vertical load on air loss, add an external rod lock or pilot 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 MFCD Double Rod Cushioned Mini Cylinder MFCD20X300S FAQ
It generates 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, with a theoretical maximum of 26.9 kgf at 1.0 MPa. Because it is a double-rod cylinder, this force is identical in both directions. The air port is 1/8".
The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. However, the variable air cushion only decelerates the piston near stroke end; it does not act as a brake. The cylinder will drift on air loss, so use an external rod lock or pilot check valve if you need to hold a load.
