Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X100S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X100S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MFCD20X100S
Twin rods and needle-set air cushions define the AirTAC MFCD20X100S, a JIS-standard round-body mini cylinder built for balanced, high-speed motion. The SUS304 stainless barrel and riveted aluminium covers form a compact envelope that is physically shorter than a comparable ISO 6432 unit, saving valuable machine space while resisting mild washdown corrosion. A piston rod exits both ends, yielding identical thrust in both directions: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa. Because the effective area is rod-side on both faces, you never sacrifice return power.
The built-in magnet (-S suffix) directly supports CMSG, DMSG, and EMSG position switches without external hardware. At 0.5 MPa, the 20 mm bore provides a safe working load of roughly 79 N, capable of vertically lifting about 6.7 kg with a 2:1 margin. The adjustable air cushion at each end decelerates the load smoothly near the stroke limits, operating at speeds from 30 to 800 mm/s. Pneumatic connections use a 1/8" port, and the male M8x1.25 rod threads allow easy tool mounting on either side.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X100S Is Used
Twin-Tool Shuttling
Drives a high-speed pick-and-place carriage where equal 131.9 N force both ways ensures consistent acceleration regardless of travel direction.
Anti-Rotation Clamping
Steadies a vertical clamping fixture against side-play during rapid descent, using the second rod to prevent twist on the 100 mm stroke.
Dual-End Ejection
Mounts a stopper on the back rod and an ejector pin on the front, simultaneously decelerating the load and pushing parts out of a jig.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X100S the Right Cylinder?
When choosing between the two available bores, match your dynamic load to the 0.5 MPa figures: the MFCD20 provides 131.9 N both ways, while stepping up to the MFCD25 yields 206.1 N. Select this 20 mm bore when your primary goal is precise, anti-rotation handling of lighter twin-tool assemblies rather than raw lifting strength. The double-rod geometry inherently resists side-play and twist, making it ideal for high-speed shuttling where a single rod might drift off-axis.
Remember that the variable air cushion only absorbs end-of-stroke shock; it does not lock or hold the load. If air pressure drops, the piston will drift, so add an external rod lock or pilot-operated check valve for suspended loads. Mounting options include LB foot, FA flange, and TC trunnion brackets (there is no SDB mount due to the dual rods). The -S magnet on this unit enables CMSG, DMSG, and EMSG sensors for drop-in position feedback.
Quick checklist
- ✓ Required force at your working pressure

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 MFCD20X100S FAQ
The double-rod design provides equal force both ways: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa. The theoretical maximum is 26.9 kgf at 1.0 MPa.
No. The variable air cushions only decelerate the piston near stroke end; they do not act as a brake. The piston will drift on air loss, so you need an external rod lock or pilot check valve for suspended loads. The -S magnet supports CMSG/DMSG/EMSG sensors.
