Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X80S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X80S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 80mm stroke, 1/8" 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 MFCD20X80S
Soaking up high-speed end-of-stroke shock with a needle-set variable air cushion at each end, this double-acting mini cylinder uses twin rods exiting both covers to deliver equal force both ways. The MFCD20X80S generates 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa in either direction, yielding a safe working load of roughly 79 N or a 6.7 kg vertical lift with a 2:1 margin. Its SUS304 stainless round body with riveted aluminium covers is JIS-standard, mounting shorter than an ISO 6432 unit of the same size.
Because the piston rod exits both ends, the second rod steadies the load, resists rotation, and provides an extra mounting point for stoppers or a second tool. This -S variant includes a built-in piston magnet for CMSG, DMSG, or EMSG switches. Air connects via 1/8" ports, the male rod thread is M8x1.25, and the bore is 20 mm. Note that the air cushion only decelerates the load near stroke end; it does not lock or hold position on air loss, so use an external rod lock or pilot check valve for holding.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X80S Is Used
Twin-Tool Transfer
Drives a 6.7 kg vertical pick-and-place head at speed, using the second rod to mount a parallel gripper while the variable cushions absorb the 80 mm stroke shock.
Anti-Rotation Indexing
Shifts a light sensor carriage between test stations where the twin rods eliminate rotational play and the needle-set cushions ensure quiet stops at 131.9 N force.
Compact Stopper Gate
Cycles a 79 N workpiece guide in a tight JIS-standard footprint, relying on the SUS304 stainless body for mild washdown resistance and the double rod for stable gating.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X80S the Right Cylinder?
Choose the MFCD20 over the MFCD25 when your application sits comfortably under 131.9 N at 0.5 MPa, as stepping up to the 25 mm bore raises the output to 206.1 N but adds weight. The 20 mm bore here is ideal for high-speed anti-rotation tasks where the twin rods prevent side-play and the adjustable air cushions quietly absorb end-of-stroke shock. With an 80 mm stroke, this unit is well-suited for compact twin-tool actuation.
Mount this JIS-standard round-body cylinder using LB foot, FA flange, or TC trunnion brackets; there is no SDB mount or back-cover code because rods exit both covers. Since this is an -S SKU, you can directly fit CMSG, DMSG, or EMSG sensors for position detection. Remember to factor in an external pilot check valve if the load must be prevented from drifting when air pressure drops.
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 MFCD20X80S FAQ
Force is equal both ways due to the double-rod design: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical max of 26.9 kgf at 1.0 MPa. It features a 20 mm bore, 1/8" air port, and an M8x1.25 male rod thread on both ends.
Yes, this -S variant has a built-in magnet for CMSG, DMSG, or EMSG switches. However, the variable air cushions only decelerate the piston near the stroke ends; they do not lock or hold position. For vertical load holding on air loss, you must install an external rod lock or pilot check valve.
