Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X15
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X15 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 15mm 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 MFCD40X15
Delivering 527.8 N of equal thrust in both directions, the AirTAC MFCD40X15 is a JIS-standard round-body mini cylinder built for high-speed anti-rotation tasks. A rod exits both aluminium covers, yielding identical push and pull forces while steadying the load. The SUS304 stainless barrel shrinks overall length compared to an ISO 6432 unit and resists mild washdown corrosion. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
Twin variable air cushions at each end absorb end-of-stroke shock for the 15 mm travel. With a 1/4 inch port and M14x1.5 male rod threads, it handles a safe working load of roughly 317 N. The cushion only decelerates the piston near stroke end; it does not lock or hold position on air loss, so add an external rod lock for vertical safety.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X15 Is Used
Twin-Tool Stamping
Drives a short 15 mm stamping action with 527.8 N of equal force, using the second rod to mount a synchronized cutter while resisting rotational twist.
High-Speed Diverter
Rapidly diverts packages on a line; the variable air cushions silently absorb the shock of the abrupt 15 mm stroke reversal without bouncing.
Compact Clamping Fixture
Clamps heavy machined parts securely. The SUS304 body fits tight spaces shorter than ISO 6432 designs, while the twin rods prevent jaw deflection.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X15 the Right Cylinder?
Choose the MFCD40X15 when you need substantial equal both-ways force in a very short stroke. At 0.5 MPa it generates 527.8 N, stepping up from the 345.6 N of the MFCD32. This 40 mm bore is ideal for compact twin-tool setups requiring high rigidity. The needle-set air cushions tame high-speed impacts at the 15 mm stroke ends.
Remember this SKU has no magnet and cannot host position sensors. Mount via LB foot, FA flange, or TC trunnion. Because there is no back cover, SDB is unavailable. The cushion decelerates but never locks the load, so fit a pilot check valve if drifting risks your assembly.
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 MFCD40X15 FAQ
It delivers equal force both ways: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical max of 107.6 kgf at 1.0 MPa. The bore-fixed air port is 1/4 inch, and the male rod thread is M14x1.5.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The twin rods and variable air cushions provide anti-rotation and shock absorption, but the cushion only decelerates and does not lock the load.
