Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X450SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X450SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 450mm 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 MFC32X450SU
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore, 450 mm stroke actuator tackles heavy-duty cycles with precision. The MFC32X450SU is a JIS-standard round-body mini cylinder featuring a SUS304 stainless barrel and riveted aluminium covers that resist mild corrosion and washdown environments. For the same bore and stroke, the MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length. It includes a flat-end U back cover and a built-in piston magnet.
A defining feature is the variable air cushion at both ends; a needle valve lets you tune the deceleration to soak up high-speed shock, protecting the load and cutting noise. Derived from the 0.5 MPa push rating, the safe working load is roughly 241 N, and it lifts about 20.5 kg vertically with a 2:1 margin. The 1/4" port feeds the 12 mm rod, and the -S suffix enables CMSG, DMSG or EMSG sensors for position feedback.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X450SU Is Used
Package Diverting
Pushes cartons at high speed across sorting lanes; the tuned air cushion absorbs the end-of-stroke impact to keep the 402.2 N thrust from jarring the conveyor frame.
Vertical Lift Gates
Raises lightweight access panels; with a 2:1 safety margin it lifts about 20.5 kg vertically, while the SUS304 barrel withstands humid dock environments.
Film Roll Tensioning
Feeds packaging material on a 450 mm stroke; the U flat-end cover mounts flush to the machine frame, and the needle-set cushion prevents sudden jerks that could tear the film.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X450SU the Right Cylinder?
When sizing this 32 mm bore, check both directions: the MFC25 provides 245.3 N at 0.5 MPa if your load is lighter, while the MFC40 offers 628.3 N for heavier demands. The adjustable air cushion is essential when cycling this 450 mm stroke at high speeds, as it smoothly decelerates the piston near the end caps. Note that this cushion only slows the piston; it does not act as a brake. Because a standard cylinder drifts when air pressure drops or a valve centres, use an external rod lock or pilot-operated check valve if you must hold a suspended load. The flat-end U rear cover suits direct mounting, and the -S magnet supports reed or electronic switches.
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 MFC32X450SU FAQ
This 32 mm bore cylinder has a 1/4" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, the piston will drift if air pressure drops or the valve centres. The variable air cushion at both ends only decelerates the piston near the stroke end to reduce shock; it is not a lock or brake. To hold a suspended load, install an external rod lock or pilot-operated check valve.
