Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X80
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X80 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 80mm 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 MFCD40X80
Twin rods exit both covers on this JIS-standard round-body mini cylinder, delivering equal 527.8 N force in both directions at 0.5 MPa while actively resisting load rotation. The SUS304 stainless barrel and riveted aluminium covers form a compact riveted body that is shorter than an ISO 6432 unit for the same 40 mm bore and 80 mm stroke, saving valuable machine space.
A needle-set variable air cushion at each end soaks up high-speed kinetic shock for smooth 30-800 mm/s motion. This non-magnet SKU cannot host a sensor; adding the -S option enables CMSG/DMSG/EMSG switches. The unit uses a 1/4 inch port and M14x1.5 male rod threads. Based on the 0.5 MPa rating, expect a safe working load around 317 N, or a vertical lift capacity of roughly 26.9 kg with a 2:1 margin.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X80 Is Used
High-Speed Transfer
Shuttles parts horizontally between machining stations using twin tooling plates, relying on the 527.8 N bidirectional force and air cushions to absorb rapid reversal shocks.
Dual-Tool Pressing
Mounts two independent stamping heads on the opposing rods to press light fittings simultaneously, utilizing the anti-rotation properties to keep the tool faces perfectly aligned.
Load Diverter
Pushes heavy cartons off a conveyor belt at high cycle rates, where the needle-set cushions quietly halt the 80 mm stroke to prevent mechanical wear.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X80 the Right Cylinder?
Choose this MFCD40 80 mm stroke model over the smaller MFCD32 (345.6 N at 0.5 MPa) when your application demands higher bidirectional thrust and superior anti-rotation stability for heavier tooling. The adjustable air cushion is essential for decelerating high-speed payloads smoothly without end-of-stroke banging. Mount via LB foot, FA flange, or TC trunnion (no SDB or back-cover exists because rods protrude both ends).
Remember that the air cushion only decelerates the piston near stroke end; it does not function as a brake. If the air supply drops, the piston will drift. To hold a load vertically during air loss, install an external rod lock or a pilot-operated check valve. Since this specific SKU lacks the -S magnet, it cannot accept position sensors.
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 MFCD40X80 FAQ
It provides equal thrust 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. The bore-fixed air port size is 1/4 inch.
No. The variable air cushion only decelerates motion at the stroke ends; it is not a brake, so the load drifts on air loss. You need an external rod lock for holding. Also, this specific SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG switches without the -S option.
