Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X350SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X350SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 350mm 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 MFC32X350SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder tackles heavier workloads with precision. A built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the U flat-end rear cover suits straightforward face mounting. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
A variable air cushion at both ends lets you dial in a needle valve to soak up end-of-stroke shock at high speeds, protecting the load and cutting noise. For the same bore and stroke, this JIS-standard round-body design is shorter than an ISO 6432 cylinder, saving valuable mounting length. Operating pressure spans 0.15 to 1.0 MPa, and the 1/4 inch port drives a 30 to 800 mm/s speed range. Based on the 0.5 MPa push rating, expect a safe working load of roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X350SU Is Used
High-Speed Carton Diversion
Uses the 402.2 N push force to deflect heavy packaging on a fast line, relying on the adjustable air cushion to stop the 350 mm stroke smoothly without slamming.
Mid-Force Component Pressing
Presses small bearings or pins into assemblies, where the 1/4 inch port maintains rapid actuation and the needle-set cushion protects fragile parts at stroke end.
Vertical Lift Gates
Raises lightweight access gates using the safe vertical lift capacity of about 20.5 kg, while the SUS304 barrel withstands humid dock environments.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X350SU the Right Cylinder?
If you need less force, step down to the MFC25 which provides 245.3 N at 0.5 MPa, or move up to the MFC40 delivering 628.3 N at 0.5 MPa for heavier demands. This 32 mm bore hits a strong middle ground for mid-range automation. The adjustable air cushion is essential when cycling the full 350 mm stroke at high speeds to prevent harsh impacts. Because this is a double-acting cylinder, it does not hold position on air loss; the piston drifts, so fit an external rod lock or pilot check valve for suspended loads. The -S magnet enables solid-state or reed sensors, and you can 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 MFC32X350SU FAQ
This 32 mm bore cylinder features a 1/4 inch port and an M10x1.25 male rod thread. 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 as a brake or lock. If air is lost, the piston will drift. For vertical loads, install an external rod lock or pilot-operated check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to track position.
