Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X175
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X175 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 175mm 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 MFCD20X175
Twin rods exit both covers of this JIS-standard round-body mini cylinder, delivering equal 131.9 N force at 0.5 MPa in both directions while steadying the load against rotation. The SUS304 stainless steel barrel and riveted aluminium covers form a compact body that is shorter than an ISO 6432 unit for the same 20 mm bore and 175 mm stroke, saving valuable machine space. A needle-set variable air cushion at each end absorbs high-speed end-of-stroke shock for quiet 30-800 mm/s operation.
This MFCD20X175 configuration uses an 8 mm rod with an M8x1.25 male thread at each end and a 1/8" port. It yields a safe working load of roughly 79 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity of around 6.7 kg with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors; the second rod still allows you to mount stoppers or a secondary tool.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X175 Is Used
Twin-Tool Transfer
Drives a 175 mm transfer stroke for a secondary pick-and-place head, using the equal both-ways 131.9 N force to push and pull lightweight trays without rotational play.
High-Speed Stopping
Cycles a part stopper at speed within the 30-800 mm/s range, relying on the needle-set variable air cushion to soften the end-of-stroke impact and protect the 6.7 kg load.
Compact Divert Gate
Fits a tight conveyor frame thanks to a body shorter than ISO 6432, using the M8x1.25 double rods to actuate a divert gate smoothly from either side.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X175 the Right Cylinder?
When choosing between the two available bores, this 20 mm version provides 131.9 N at 0.5 MPa, whereas the MFCD25 delivers 206.1 N. Pick the 20 mm bore for lighter, high-speed tasks where the twin-rod anti-rotation feature and twin-tool mounting are more critical than raw thrust. The adjustable air cushions make it ideal for shock-sensitive moves, but remember the cushion only decelerates the piston near the stroke end—it does not act as a brake.
For load holding during air loss or when a valve is centered, you must add an external rod lock or a pilot-operated check valve, as the piston will drift. Mounting options include LB foot, FA flange, and TC trunnion brackets (there is no SDB or back-cover code because a rod exits both ends). If your application requires position sensing, select the -S magnet variant to enable CMSG, DMSG or EMSG switches.
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 MFCD20X175 FAQ
This double-acting, double-rod cylinder generates equal force in both directions: 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 8 mm rod with an M8x1.25 male thread on each end.
This specific SKU does not have the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. The variable air cushion at both ends only decelerates the piston near the stroke end to reduce shock; it is not a lock or brake, so you need an external rod lock or pilot check valve to hold a load on air loss.
