Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X10S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X10S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 10mm 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 MFCD20X10S
Twin rods exit both covers of the AirTAC MFCD20X10S, delivering equal 131.9 N thrust at 0.5 MPa in both directions while actively resisting rotation. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel with riveted aluminium covers. Because the second rod occupies the rear, there is no back-cover option. A needle-set variable air cushion at each end absorbs end-of-stroke shock, enabling smooth high-speed motion across the short 10 mm travel. The built-in -S magnet supports CMSG, DMSG and EMSG switches for position sensing.
For such a compact 20 mm bore unit, the 1/8" port and M8x1.25 male rod thread provide robust performance. The body is notably shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting space. Based on the 0.5 MPa force, expect a safe working load around 79 N, or a vertical lift of roughly 6.7 kg with a 2:1 margin. Note that the air cushion only decelerates the load near stroke end; it does not function as a brake, so use an external rod lock or pilot check valve if you need to hold position on air loss.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X10S Is Used
Short-Stroke Gating
Uses the 10 mm travel to quickly divert small parts on a conveyor, relying on the 131.9 N force and twin rods to keep the gate steady without twisting.
Twin-Tool Clamping
Mounts a secondary stopper on the rear rod to clamp a delicate workpiece from both sides simultaneously, with the air cushion preventing impact damage.
Compact Ejector
Fits into tight machine cells to eject light molded components at speed, where the SUS304 barrel handles occasional washdown and the short body saves space.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X10S the Right Cylinder?
Choose the MFCD20 over the MFCD25 when space is tight and 131.9 N at 0.5 MPa is sufficient, as the larger bore delivers 206.1 N but demands more room. The 10 mm stroke excels in short, high-speed pick-and-place tasks where the twin rods prevent side-play and the variable air cushions quietly soak up shock. Mount via LB foot, FA flange or TC trunnion (no SDB available). The -S magnet on this SKU allows CMSG, DMSG or EMSG sensors to track both ends of travel.

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 MFCD20X10S FAQ
It generates 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, with a theoretical max of 26.9 kgf at 1.0 MPa. Force is equal in both directions because it is a double-rod cylinder. The air port is 1/8".
No, the variable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a brake or lock. The piston will drift on air loss. For load holding, install an external rod lock or pilot check valve.
