Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CM 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 MFC32X70CM
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore double-acting mini cylinder uses a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The SUS304 stainless round barrel and riveted aluminium covers resist mild corrosion and washdown. For the same bore and stroke, the JIS-standard body is shorter than an ISO 6432 cylinder, saving valuable mounting length.
It features a 70 mm stroke, a 1/4 inch port, and a CM round-end rear cover. Based on the 0.5 MPa push figure, it handles a safe working load of about 241 N, lifting roughly 20.5 kg vertically with a 2:1 margin. This SKU has no magnet, so it cannot take a sensor; order the -S variant for CMSG, DMSG or EMSG switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CM Is Used
Bottle Diverting
Pushes product lanes at high speed where the adjustable air cushion prevents glass bottles from jarring at the 70 mm stroke end.
Flap Folding
Drives carton flaps with a safe 241 N working load, using the cushion needle to soften impact on rigid cardboard.
Light Pressing
Applies steady 402.2 N clamping force on small assemblies, benefiting from the compact JIS body length in tight cells.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X70CM 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. The variable air cushion matters most when cycling heavy loads at high speed, letting you dial in the deceleration to protect the workpiece. Remember the cushion only decelerates near the stroke end; it is not a brake. To hold a load on air loss, fit an external rod lock or pilot check valve. Mount via LB foot, FA flange, SDB pivot or TC trunnion.
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 MFC32X70CM FAQ
It has a 1/4 inch port and a 12 mm rod. The double-acting thrust is 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot take a switch. You need the -S version to use CMSG, DMSG or EMSG sensors. The SUS304 stainless build resists mild corrosion, and the CM round-end cover suits standard rear mounting.
