Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X100
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X100 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MFCD20X100
Built for high-speed anti-rotation tasks, the MFCD20X100 uses a needle-set variable air cushion at each end to soak up end-of-stroke shock. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, giving you a shorter mounting length than an ISO 6432 unit for the same 20 mm bore and 100 mm stroke.
Because a rod exits both covers, the output is equal both ways at 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, with a 1/8" port and M8x1.25 male rod thread. The twin rods steady the load and cut side-play, yielding a safe working load of about 79 N or a 6.7 kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X100 Is Used
Twin-Tool Transfer
Shifts parts horizontally on a 100 mm stroke using twin rods to prevent rotation during rapid 79 N transfers.
Soft-Stop Pressing
Depresses delicate components with equal 131.9 N force while the needle air cushion absorbs high-speed impact.
Dual-End Sorting
Uses the second protruding rod to mount a stopper or guide while cycling 100 mm at up to 800 mm/s.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X100 the Right Cylinder?
Choose the MFCD20 over the MFCD25 when 131.9 N at 0.5 MPa is sufficient, as the larger bore offers 206.1 N but adds bulk. The twin-rod layout with variable air cushioning is ideal for shock-sensitive twin-tool setups running at 30-800 mm/s. Mount via LB foot, FA flange, or TC trunnion, but note there is no SDB or back-cover code since rods exit both ends.
Remember that the air cushion only decelerates the piston near stroke end and does not act as a lock. If your application must hold a load on air loss, add an external rod lock or pilot-operated check valve. For position sensing, select the -S magnet variant instead of this base model.
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 MFCD20X100 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 max of 26.9 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant for sensing. The twin rods still provide anti-rotation, and the variable air cushion decelerates the load.
