Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X175S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X175S 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 MFCD20X175S
Twin rods exiting both SUS304 stainless covers give the AirTAC MFCD20X175S equal push and pull thrust while actively resisting rotation. This JIS-standard round-body mini cylinder delivers 131.9 N at 0.5 MPa in both directions, yielding a safe working load of roughly 79 N or a 6.7 kg vertical lift with a 2:1 margin.
Adjustable needle air cushions at each end absorb end-of-stroke shock for smooth 30-800 mm/s operation. The riveted aluminium body is shorter than a comparable ISO 6432 unit, and the -S suffix adds a piston magnet for CMSG, DMSG or EMSG switches. It uses a 1/8" port and M8x1.25 male rod threads.

Theoretical Output Force (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 132 N |

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X175S Is Used
Twin-Tool Transfer
Drives a 175 mm transfer stroke with a second tool on the back rod, using equal 131.9 N thrust for balanced push and pull.
Anti-Rotation Indexer
Twin 8 mm rods steady the load and cut side-play during high-speed indexing, while needle cushions soften the end stop.
Compact Stopper Gate
Saves machine length versus ISO 6432 designs, using its built-in magnet and 1/8" port to trigger CMSG sensors mid-stroke.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X175S the Right Cylinder?
Choose the 20 mm bore over the MFCD25 (206.1 N at 0.5 MPa) when your payload is light and space is tight. The double-rod layout is ideal for high-speed anti-rotation tasks or mounting a second tool on the back rod. Note that the air cushions only decelerate the load; they do not lock it. Use an external rod lock or pilot check valve if you must hold position on air loss. Mount via LB foot, FA flange or TC trunnion (no SDB).
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 MFCD20X175S FAQ
It provides equal force both ways: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical max of 26.9 kgf at 1.0 MPa. The air port is 1/8".
No. The needle air cushions only decelerate the piston near stroke end; they do not lock the load. For holding, use an external rod lock. The -S magnet supports CMSG, DMSG and EMSG switches.
