Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X10
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X10 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 10mm 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 MFCD20X10
Needle-set air cushions at both ends define the AirTAC MFCD20X10, a JIS-standard round-body mini cylinder built for high-speed shock absorption. The SUS304 stainless barrel and riveted aluminium covers form a compact body that is shorter than an ISO 6432 unit for the same 20 mm bore and 10 mm stroke, saving valuable mounting length. Because it is double-acting with a double rod, force stays equal both ways at 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, yielding a theoretical maximum of 26.9 kgf at 1.0 MPa.
The twin 8 mm rods exit both covers to steady the load and resist rotation, while the back rod can mount a stopper or second tool. With a 1/8" port and a 10 mm stroke, it delivers a safe working load of roughly 79 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity of about 6.7 kg with a 2:1 margin. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X10 Is Used
Twin-Tool Transfer
Ideal for short 10 mm pick-and-place shifts where the second rod mounts a parallel gripper, moving roughly 6.7 kg vertically with a 2:1 safety margin at 0.5 MPa.
Anti-Rotation Indexing
The dual 8 mm rods prevent side-play during high-speed cycling, keeping precision stops aligned without twisting under the 131.9 N both-ways force.
Shock-Sensitive Clamping
Needle-set air cushions at both ends absorb the impact of rapid 10 mm strokes, protecting delicate electronics or thin film components during clamping.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X10 the Right Cylinder?
When choosing between this 20 mm bore and the MFCD25, compare the both-ways force: the MFCD20 provides 131.9 N at 0.5 MPa, while the MFCD25 offers 206.1 N. Pick the 20 mm bore for lighter, high-speed anti-rotation tasks where twin tools are mounted on the rods. The variable air cushion at each end soaks up end-of-stroke shock, but remember it only decelerates the piston—it is not a lock or brake. If your application must hold a vertical load on air loss, add an external rod lock or pilot check valve. For mounting, use LB foot, FA flange or TC trunnion brackets (there is no SDB or back-cover code because rods exit 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 MFCD20X10 FAQ
It delivers equal force in both directions because of the double-rod design: 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. The air port is 1/8".
This SKU lacks the -S magnet, so it cannot take CMSG, DMSG or EMSG switches. The variable air cushions only decelerate the piston near stroke end to reduce shock; they do not lock or hold the load. For position holding, use an external rod lock.
