Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X15
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X15 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 15mm 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 MFCD20X15
Needle-set air cushions at both ends absorb end-of-stroke shock, making this 15 mm stroke MFCD20X15 ideal for rapid, short-throw cycles. As a JIS-standard round-body mini cylinder with a SUS304 stainless barrel and riveted aluminium covers, it is shorter than an ISO 6432 unit of the same bore and stroke, saving valuable mounting length.
Because a rod exits both covers, the twin rods resist rotation and deliver equal force in both directions: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa via the 1/8" port. This yields a safe working load of roughly 79 N, or a vertical lift of about 6.7 kg with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X15 Is Used
Short-Throw Part Transfer
Uses the twin rods to push small components sideways 15 mm between conveyor belts, relying on the air cushion to stop the rapid 131.9 N stroke smoothly.
Twin-Tool Clamping
Mounts a clamp on the front rod and a stopper on the back rod to secure a workpiece, using the equal both-ways force to hold alignment during machining.
Compact Ejector Station
Fits into tight machine frames to eject light molded parts, taking advantage of the shorter JIS body length and the 6.7 kg vertical lift capacity.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X15 the Right Cylinder?
Choose the MFCD20 (131.9 N at 0.5 MPa) for lighter, compact tasks, or step up to the MFCD25 (206.1 N at 0.5 MPa) if your load exceeds the 79 N safe working threshold. The 15 mm stroke excels in tight spaces where high-speed twin-tool actuation needs the shock absorption of a variable air cushion.
Mount via LB foot, FA flange, or TC trunnion (no SDB or back-cover code exists). Remember that the cushion only decelerates near stroke end; it is not a brake. For position holding on air loss, install 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 MFCD20X15 FAQ
The double-rod design provides equal force both ways: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical maximum of 26.9 kgf at 1.0 MPa. It uses a 1/8" port and an M8x1.25 male rod thread on both ends.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. The variable air cushion at both ends handles high-speed deceleration, while the second rod prevents load rotation.
