Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40SCA 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 MFC32X40SCA
Dial in end-of-stroke deceleration with the AirTAC MFC32X40SCA, a JIS-standard round-body mini cylinder built for double-acting service. A needle-set variable air cushion at both ends soaks up high-speed shock to protect your payload, while the SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown. For the same 32 mm bore and 40 mm stroke, this riveted body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
This 32 mm bore generates 402.2 N of push force and 345.6 N of pull at 0.5 MPa, peaking at an 82 kgf theoretical maximum at 1.0 MPa. The integrated -S piston magnet supports CMSG, DMSG and EMSG position sensing, and the rear CA pivot cover simplifies angular mounting. Factoring a 2:1 safety margin, it lifts about 20.5 kg vertically, yielding a safe working load near 241 N. Air connects via a 1/4" port.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40SCA Is Used
Package Diverting
Handles 20 kg cartons at high cycle rates on a sorting line, using the needle-adjustable air cushion to silently absorb the 40 mm stroke impact.
Light Press Fit
Applies up to 402.2 N of push force to seat small bearings, relying on the SUS304 stainless body to resist coolant mist in the machining cell.
Pallet Stopper
Halts incoming pallets via the rear CA pivot mount, with the -S magnet triggering a DMSG switch to confirm the stop position.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40SCA the Right Cylinder?
If 245.3 N from the MFC25 is insufficient, this 402.2 N model is the right step up; should you need more thrust, the MFC40 provides 628.3 N at 0.5 MPa. The variable air cushion is essential when cycling at high speeds or moving heavy masses, as it prevents harsh end-of-stroke impacts. Remember that the cushion only decelerates the piston and does not lock the rod—if air pressure drops, the load will drift, so fit an external rod lock or pilot check valve for secure holding. Mounting is versatile with the CA pivot, and the -S magnet ensures compatibility with reed and electronic sensors.
Quick checklist

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 MFC32X40SCA FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa, and the air port is 1/4".
No, the variable air cushion only decelerates the piston near the stroke end and acts purely as a shock absorber, never as a brake. If air pressure drops, the piston will drift, so you must use an external rod lock or pilot-operated check valve to hold a suspended load.
