The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X50 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 50mm 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.
Needle-set variable air cushions at both ends define this double-acting MFCD32X50, soaking up high-speed end-of-stroke shock while twin rods deliver equal 345.6 N force at 0.5 MPa in both directions. Built as a JIS-standard round-body mini cylinder, its SUS304 stainless barrel and riveted aluminium covers form a shorter overall length than an ISO 6432 unit of the same bore and stroke, resisting mild corrosion and washdown.
The twin 12 mm rods exit both covers to steady the load and cut side-play, allowing you to mount a second tool or stopper on the back end. This non-magnet SKU cannot host a position sensor; order the -S variant to enable CMSG, DMSG or EMSG switches. With a 1/4" port and a safe working load around 207 N (roughly 60% of the 0.5 MPa figure), it yields a vertical lift capacity of about 17.6 kg with a 2:1 margin.

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 dual-gripper assembly at high speed, using the 345.6 N bidirectional force and needle-set cushion to swap parts smoothly without end-stroke bounce.
Steadies a heavy diverting flap across the belt; the second rod eliminates side-play while the air cushion absorbs the 50 mm stroke impact at 800 mm/s.
Uses both extending rods simultaneously to halt and align a 17 kg workpiece carrier, maintaining equal push and pull thrust for precise centring.
Choose this 32 mm bore over the MFCD25 (206.1 N @0.5 MPa) when you need roughly 70% more thrust, or step up to the MFCD40 (527.8 N @0.5 MPa) for heavier tooling. The variable air cushion shines in high-speed anti-rotation tasks where shock-sensitive twin-tool mounting is required, operating smoothly between 30-800 mm/s. Mounting options include LB foot, FA flange and TC trunnion, with no SDB or back-cover code available since rods exit both ends.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If air pressure drops or the valve is centred, the piston will drift. For vertical or suspended loads that must hold position on air loss, fit an external rod lock or a pilot-operated check valve.
Quick checklist
It generates 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, equal in both directions due to the double-rod design. The theoretical max is 70.5 kgf at 1.0 MPa, and the air port is 1/4".
This specific SKU lacks a magnet and cannot take CMSG/DMSG/EMSG switches; you need the -S variant for sensing. The variable air cushion only decelerates near stroke end and is not a brake, so fit an external rod lock or pilot check valve to hold loads on air loss.
