Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 70mm stroke, 1/4" 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 MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CA
Dial in end-of-stroke deceleration with the AirTAC MFC32X70CA, a JIS-standard round-body mini cylinder built for high-speed actuation. Tuning the needle valve on its variable air cushion at both ends absorbs shock, protecting your payload and cutting workshop noise. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the included CA rear pivot cover simplifies rear-clevis mounting.
Delivering 402.2 N of push force and 345.6 N of pull force at 0.5 MPa, this double-acting actuator uses a 1/4" port and a 12 mm rod. It yields a safe working load of about 241 N, lifting roughly 20.5 kg vertically with a 2:1 margin. For the same bore and stroke, the compact riveted body is shorter than an ISO 6432 cylinder, saving valuable machine space.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CA Is Used
Package Diverting
Shifts small to medium cartons at speed on a sorting line; the variable air cushion prevents harsh slams that could topple unstable boxes during the 70 mm transfer.
Light Pressing
Applies a steady 402.2 N clamping force for seating bearings or pins, using the adjustable end-cushion to protect the tooling from impact damage at rapid cycle rates.
Flap Folding
Drives a folding blade on a carton erector, relying on the SUS304 stainless barrel to withstand washdown in packaging areas handling food or beverages.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CA the Right Cylinder?
If 245.3 N from the MFC25 is too light and 628.3 N from the MFC40 is excessive, this 32 mm bore hits the sweet spot at 402.2 N push. The adjustable air cushion proves its worth when driving heavier masses at high cycling speeds, letting you bleed off kinetic energy smoothly rather than slamming the covers. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors; add an -S variant if you require position detection.
Keep in mind the cushion needle only decelerates the piston near the stroke end—it is not a brake. If air pressure drops or the valve is centred, the rod will drift, so fit an external rod lock or pilot-operated check valve for suspended loads. You can pair the standard CA back cover with LB foot, FA flange, SDB pivot, or TC trunnion mounts to suit your frame.
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 MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CA FAQ
This double-acting cylinder uses a 1/4" port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa. Its theoretical maximum force is 82 kgf at 1.0 MPa, with a 12 mm rod and M10x1.25 male thread.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select an MFC32X70CA-S variant to enable magnetic sensing. The standard version still features the variable air cushion and SUS304 stainless barrel.
