Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X200S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X200S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 200mm 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 MFCD40X200S
Twin rods and needle-set air cushions define the MFCD40X200S, a JIS-standard round-body mini cylinder built for balanced, high-speed motion. The SUS304 stainless barrel and riveted aluminium covers form a compact body that is physically shorter than an ISO 6432 unit of the same 40 mm bore and 200 mm stroke, saving valuable machine space while resisting mild washdown corrosion. Because a 16 mm rod exits both covers, the thrust is identical in both directions at 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa.
The dual-rod geometry prevents side-play and stops rotation without external guides, letting you mount a second tool or stopper on the back end. With a 1/4" port and M14x1.5 male rod threads, this unit includes a piston magnet (-S) for CMSG, DMSG or EMSG sensors. For sizing, expect a safe working load of about 317 N (60% of the 0.5 MPa force), or a vertical lift capacity near 26.9 kg with a 2:1 margin.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X200S Is Used
Dual-Tool Transfer
Uses the 527.8 N force to push parts on the forward stroke and retracts a second gripper on the back rod, keeping cycle times fast without adding a separate cylinder.
Anti-Rotation Stamping
Twin 16 mm rods absorb side torque during pressing, while the needle-set air cushions quietly stop the 200 mm travel at high speed to protect the tooling.
Vertical Lift Stopper
Raises a 26 kg pallet load with a 2:1 safety margin, relying on the balanced both-ways thrust and a pilot check valve to prevent drift on air loss.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X200S the Right Cylinder?
Choose the MFCD40 over the MFCD32 when you need more muscle: the 40 mm bore gives 527.8 N at 0.5 MPa versus 345.6 N for the 32 mm. This extra thrust is ideal for moving heavier jigs, while the variable air cushions at both ends soak up the shock of fast 200 mm strokes. The twin rods keep the load steady and resist twist during rapid reversal.
Remember that the air cushion only decelerates the piston near the end of stroke; it does not lock or hold the load. If power drops, the piston will drift, so add an external rod lock or pilot check valve for vertical safety. Mounting options include LB foot, FA flange and TC trunnion brackets. Because this is an -S SKU, you can directly fit CMSG, DMSG or EMSG switches for position sensing.
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 MFCD40X200S FAQ
The double-rod design provides 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" port and a 16 mm rod on each end.
It features a variable air cushion at both ends to decelerate high-speed motion smoothly. The -S option includes a piston magnet for CMSG, DMSG or EMSG switches. The cushions slow the piston but do not lock the load.
