Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X20S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X20S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 20mm 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 MFCD32X20S
Twin rods and needle-set air cushions define the AirTAC MFCD32X20S, a JIS-standard round-body mini cylinder built for smooth, anti-rotation motion at high speed. The SUS304 stainless barrel and riveted aluminium covers keep the envelope shorter than an ISO 6432 unit of the same bore and stroke, saving valuable machine space while resisting mild washdown.
Because a rod exits both covers, the double-acting piston generates identical force in both directions: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa via its 1/4" port. This yields a safe working load of about 207 N, or a vertical lift of roughly 17.6 kg with a 2:1 margin. The -S suffix means a built-in magnet is present for CMSG, DMSG or EMSG switches.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X20S Is Used
Twin-Tool Stamping
Drives a short-stroke upper and lower tooling set simultaneously, using the 345.6 N equal thrust and needle cushions to strike cleanly without rebound.
Anti-Rotation Diverter
Pushes a diverter arm across a belt at high speed; the twin rods eliminate side-play and the air cushions absorb the abrupt 20 mm stroke stops.
Vertical Lift Gate
Lifts a roughly 17.6 kg sorting flap with a 2:1 safety margin, relying on equal both-ways force to raise and lower the gate smoothly.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X20S the Right Cylinder?
When sizing across the range, this 32 mm bore sits neatly between the MFCD25 at 206.1 N and the MFCD40 at 527.8 N at 0.5 MPa. Choose the MFCD32X20S when a short 20 mm stroke twin-tool mechanism needs equal thrust both ways and high-speed end-cushioning to prevent shock. The second rod steadies the load and resists rotation, while the back rod can mount a sensor or stopper.
Remember that the variable air cushion only decelerates the piston near stroke end; it is not a brake. If the load must be held during air loss, fit an external rod lock or pilot check valve. Mounting options include LB foot, FA flange or TC trunnion (no SDB), and the -S magnet enables 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 MFCD32X20S FAQ
It delivers equal force in both directions because of the double-rod design: 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a theoretical max of 70.5 kgf at 1.0 MPa. The air port is 1/4".
The variable air cushions at both ends only decelerate the piston near stroke end to reduce shock; they do not lock or hold the load on air loss. The -S suffix provides a built-in magnet for CMSG, DMSG or EMSG switches.
