Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X280
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X280 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 280mm 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 MFCD40X280
Delivering 527.8 N of force in both directions at 0.5 MPa, the AirTAC MFCD40X280 is a JIS-standard round-body mini cylinder built for high-speed anti-rotation tasks. A 16 mm rod exits both aluminium covers, yielding equal thrust on extension and retraction while steadying the load against side-play. The SUS304 stainless barrel resists mild corrosion and washdown, and because the riveted body is shorter than an ISO 6432 cylinder of the same bore and stroke, it saves valuable mounting length. A needle-set variable air cushion at each end soaks up end-of-stroke shock across the 280 mm travel.
This non-magnet SKU cannot host position sensors; add the -S option for CMSG, DMSG or EMSG switches. With a 1/4 inch port and M14x1.5 male rod threads, it handles a safe working load of roughly 317 N. Note that the air cushion only decelerates the piston near stroke end and does not act as a brake; fit an external rod lock or pilot check valve if you need to hold a load vertically.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X280 Is Used
Twin-Tool Stamping
Drives a high-speed dual-head stamping press over 280 mm, using the second rod to keep the upper tool perfectly aligned while generating 527.8 N of impact force.
Dual-End Transfer
Pushes parts across a conveyor from either side with equal 527.8 N thrust, relying on the variable air cushion to halt the 280 mm travel smoothly without shock.
Vertical Lift Stopper
Acts as an anti-rotation stopper for descending pallets, using both rods to resist side-play and safely managing a working load of about 317 N.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X280 the Right Cylinder?
When sizing the MFCD family, compare this 40 mm bore against the MFCD32, which provides 345.6 N at 0.5 MPa. Choose the MFCD40X280 when your application demands the full 527.8 N both ways across a long 280 mm stroke, especially for twin-tool setups where the second rod prevents rotation at high speed. If your load is lighter, the 32 mm bore offers a more compact footprint.
Mounting options include LB foot, FA flange and TC trunnion brackets; there is no SDB mount or back-cover code because a rod exits both ends. Remember that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors without upgrading to an -S variant.
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 MFCD40X280 FAQ
The MFCD40X280 is a double-acting, double-rod cylinder with equal force both ways: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical maximum of 107.6 kgf at 1.0 MPa. It uses a 1/4 inch air port and M14x1.5 male rod threads.
This SKU has no magnet and cannot take CMSG, DMSG or EMSG sensors; you need the -S variant for sensing. The variable air cushion at both ends only decelerates the piston near stroke end to reduce shock, it does not lock or hold the load. Use an external rod lock or pilot check valve for position holding.
