Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X10
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X10 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 10mm stroke, 1/4" 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 MFCD40X10
Twin rods exit both covers of this JIS-standard round-body mini cylinder, yielding equal 527.8 N force in both directions at 0.5 MPa while steadying the load against rotation. The SUS304 stainless barrel and riveted aluminium covers form a compact body that is shorter than an ISO 6432 unit of identical bore and stroke, saving valuable machine space.
Needle-set variable air cushions at each end soak up end-of-stroke shock for high-speed 30-800 mm/s travel, while the 1/4" port feeds the 40 mm bore. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors; it yields a safe working load of about 317 N, or a 26.9 kg vertical lift with a 2:1 margin.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X10 Is Used
Short-Stroke Clamping
Twin rods resist twisting as the 527.8 N force clamps parts securely on a machining line.
Rapid Transfer Pusher
Needle air cushions absorb the impact of fast 10 mm strokes pushing components between stations.
Dual-Tool Actuation
Mount a stopper or secondary tool on the back rod while the front rod drives a 26.9 kg payload.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X10 the Right Cylinder?
For 40 mm bore tasks needing 527.8 N both ways at 0.5 MPa, this 10 mm stroke unit fits tight spots; step down to MFCD32 (345.6 N) if your load is lighter. The twin-rod layout prevents side-play, and the needle cushions decelerate fast moves, though they do not lock the piston on air loss—add an external rod lock or pilot check valve for holding.
Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover code exists because rods exit both ends). Because this specific SKU has no -S magnet, it cannot host position sensors; order an -S variant for CMSG, DMSG or EMSG switches.
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 MFCD40X10 FAQ
It generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical max of 107.6 kgf at 1.0 MPa. Force is equal in both directions. The 40 mm bore uses a 1/4" port.
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; they do not lock or hold the load on air loss. Use an external rod lock for holding.
