The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X50S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 50mm 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.
Twin rods exit both covers of the AirTAC MFCD20X50S, delivering equal 131.9 N force at 0.5 MPa in both directions while resisting side-play. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, giving you a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke. A built-in piston magnet (-S) enables CMSG, DMSG or EMSG switches for position sensing.
Needle-set variable air cushions at both ends soak up high-speed end-of-stroke shock for quiet, smooth operation across the 30-800 mm/s speed range. The twin rods steady the load and provide a second mounting point for stoppers or tools. With a 1/8" port and M8x1.25 male rod threads, it yields a safe working load of about 79 N (roughly 60% of the 0.5 MPa figure) or a 6.7 kg vertical lift with a 2:1 margin.

Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

MF-family variants: MF / MFC (double acting ±cushion), MSF / MTF (single acting push / pull), MFD / MFCD (double rod ±cushion), MFJ / MFCJ (adjustable stroke ±cushion). Back covers CA / U / CM. Mounting LB / FA / SDB / TC.
Drives a 6 kg parts shuttle back and forth at speed, using the second rod to mount a stopper while the cushion absorbs end-of-stroke shock.
Lifts and places delicate electronics with equal 131.9 N force both ways, preventing jaw twist during high-speed vertical movements.
Fits into tight machinery frames thanks to the short JIS body, steadying a diverting flap against side-load without drifting under shock.
Choose the MFCD20 over the MFCD25 when your application sits comfortably under 131.9 N at 0.5 MPa; step up to the 206.1 N MFCD25 only if you need extra thrust. The variable air cushion and double-rod build suit high-speed anti-rotation tasks and shock-sensitive twin-tool setups. For position feedback, this -S variant supports CMSG, DMSG and EMSG sensors.
Mount via LB foot, FA flange or TC trunnion (there is no SDB option because a rod exits both ends). Remember that the air cushion only decelerates near the stroke end—it is not a brake. If the load must hold position on air loss, fit an external rod lock or pilot-operated check valve.
Quick checklist
The double-rod design provides equal force both ways (rod-side area): 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 uses a 1/8" port.
No, the variable air cushion only decelerates near stroke end; it is not a lock. The piston drifts on air loss, so use an external rod lock for holding. The -S magnet allows CMSG, DMSG and EMSG switches.
