Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MFC32X40SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted aluminium covers and SUS304 stainless barrel shrug off mild corrosion and washdown. Because the -S suffix denotes a built-in piston magnet, you can mount CMSG, DMSG or EMSG reed or electronic switches directly for position sensing.
For the same bore and stroke, this JIS-standard round-body unit is physically shorter than an ISO 6432 cylinder, saving valuable mounting length. Driven by a 1/4 inch air port and a 12 mm rod with an M10x1.25 male thread, it achieves a safe working load of roughly 241 N. With a 2:1 safety margin, it lifts about 20.5 kg vertically. The rear closure uses a CM round-end cover style.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40SCM Is Used
Package Diverting
Cushions the 402.2 N stroke at high cycle rates to push cartons off a sorting line without jarring the mechanism.
Light Press Fit
Drives a 20.5 kg vertical assembly tooling head down smoothly, using the needle adjustment to prevent harsh bottoming.
Pallet Stopper
Halts incoming pallets on a 1/4 inch ported air circuit, relying on the SUS304 body to endure humid dock environments.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40SCM the Right Cylinder?
If 245.3 N at 0.5 MPa from the smaller MFC25 is insufficient, this 32 mm bore provides the necessary step up; should your payload require more thrust, the larger MFC40 offers 628.3 N. The adjustable cushion is essential when cycling heavy loads at high speed, as it decelerates the piston smoothly to reduce noise and impact. Note that the cushion only slows the piston near stroke end and does not function as a lock; if you need to hold a load vertically during air loss, install an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion brackets 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 MFC32X40SCM FAQ
This 32 mm bore cylinder features a 1/4 inch air port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end and acts purely as a shock absorber, never a brake. If power fails, the piston will drift. You must add an external rod lock or pilot check valve to hold a vertical load safely.
