Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X20
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X20 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 20mm 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 MFCD20X20
Twin rods exiting both covers give the AirTAC MFCD20X20 equal 131.9 N force in both directions, while a needle-set variable air cushion at each end soaks up high-speed end-of-stroke shock. This JIS-standard round-body mini cylinder uses a SUS304 stainless barrel with riveted aluminium covers, offering mild corrosion resistance without the bulk of a tie-rod or profile body.
For the same 20 mm bore and 20 mm stroke, this compact riveted build is shorter than an ISO 6432 cylinder, saving valuable mounting length. It yields a safe working load of roughly 79 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity of about 6.7 kg with a 2:1 margin. The 1/8" port and M8x1.25 male rod thread facilitate straightforward integration, though note this specific SKU lacks a magnet and cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X20 Is Used
Twin-Tool Transfer
Ideal for shuttling small electronic parts at high speed, using the second rod to mount a synchronized stopper while the cushion absorbs end-of-stroke impact.
Anti-Rotation Clamping
Provides stable, non-rotating clamping on light machined components, leveraging the 131.9 N bidirectional force and twin-rod guidance to prevent side-play.
Compact Strip Ejection
Fits into tight assembly machine envelopes where a shorter-than-ISO-6432 body is required, safely ejecting delicate plastic widgets with a 79 N working load.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X20 the Right Cylinder?
When choosing between this 20 mm bore and the MFCD25, compare the actual thrust: the MFCD20X20 provides 131.9 N at 0.5 MPa, whereas the MFCD25 delivers 206.1 N. Select the 20 mm bore for lighter, high-speed anti-rotation tasks where shock-sensitive twin-tool mounting is required, and step up to the 25 mm bore if your load exceeds the 79 N safe working threshold. Both options operate at 30-800 mm/s.
Mounting options include LB foot, FA flange, and TC trunnion styles, with no SDB or back-cover code available due to the dual-rod design. Remember that the variable air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your application must hold a vertical load during air loss, install an external rod lock or pilot-operated check valve. To add position sensing, you must specify the -S magnet variant.
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 MFCD20X20 FAQ
The MFCD20X20 delivers equal force in both directions because it is a double-rod cylinder: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical maximum of 26.9 kgf at 1.0 MPa. It features a 1/8" air port and an M8x1.25 male rod thread on both ends.
This specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensing. The variable air cushion at both ends only decelerates the piston near the stroke end to reduce shock, it does not lock or hold the load on air loss.
