Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 400mm 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 MFC32X400U
Tuned for rapid 400 mm strokes, the AirTAC MFC32X400U relies on a needle-set variable air cushion at both ends to decelerate heavy loads smoothly, cutting end-of-travel shock and noise. This JIS-standard round-body mini cylinder pairs a SUS304 stainless steel barrel with riveted aluminium covers to resist mild corrosion and washdown. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable mounting length.
Operating on filtered air at 0.15-1.0 MPa, this double-acting actuator features a 32 mm bore, a 1/4" port, and an M10x1.25 male rod thread. It pushes with 402.2 N and pulls with 345.6 N at 0.5 MPa. Derived from that thrust, the safe working load is roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400U Is Used
Package Diverting
Pushes parcels across sorting lanes at high speed, using the variable air cushion to halt the 400 mm stroke gently without jarring the belt mechanics.
Vertical Material Lift
Raises components weighing up to 20.5 kg in a 2:1 margin setup, leveraging the 402.2 N push force to elevate stock between processing tiers.
Carton Forming Press
Drives forming heads through long travel cycles, relying on the SUS304 stainless barrel to endure mildly humid or washdown packaging environments.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400U the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MFC25 yields 245.3 N of push force at 0.5 MPa, while moving up to the MFC40 provides 628.3 N. Choose this model when moving heavier masses at high speeds where the adjustable air cushion is essential to prevent impact damage. Note that the cushion only decelerates near the stroke end; it does not function as a lock or brake.
Because this configuration uses a U flat-end rear cover, mounting orientation must be planned accordingly. If your application requires position feedback, you must select the -S magnet variant, as this base SKU cannot host a magnetic switch. Furthermore, a standard cylinder drifts when air pressure is lost or valves are centered; for suspended loads, install an external rod lock or pilot-operated check valve.
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 MFC32X400U FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. It generates 402.2 N of push force and 345.6 N of pull force at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, meaning it cannot host CMSG, DMSG, or EMSG sensors. To add position sensing, you must select the -S variant. The cylinder also features a U flat-end rear cover and a variable air cushion that decelerates the piston near stroke end.
