Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-40STC
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-40STC is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 100mm 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 MFCJ Adjustable Mini Cylinder MFCJ32X100-40STC
Dial in exact end positions and absorb high-speed impact with the AirTAC MFCJ32X100-40STC. This JIS-standard round-body mini cylinder features a 40 mm adjustable extend window (usable 60-100 mm) paired with needle-set variable air cushions at both ends. The riveted SUS304 stainless barrel and aluminium covers form a compact body that is physically shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length while resisting mild washdown corrosion.
Driven by a 12 mm rod through a 1/4" port, the 32 mm bore delivers 402.2 N of push force at 0.5 MPa. That translates to a safe working load of roughly 241 N, or about 20.5 kg of vertical lift with a 2:1 margin. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches, and the included TC trunnion mount simplifies pivoting setups.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-40STC Is Used
High-Speed Diverting
Tune the 40 mm extend window to hit diverters precisely on varying package sizes, using the variable air cushion to halt the 402.2 N thrust smoothly without slamming.
Carton Forming Stops
Adjust the end position on the fly for different carton depths; the SUS304 barrel handles occasional washdown while the TC trunnion accommodates slight misalignment.
Light Press Fitting
Lift approximately 20.5 kg of tooling vertically with a 2:1 safety margin, relying on the needle cushion to soften the 100 mm stroke impact at high cycle rates.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-40STC the Right Cylinder?
Choose the 32 mm bore for moderate thrust needs: it provides 402.2 N push at 0.5 MPa, sitting between the smaller MFCJ25 at 245.3 N and the larger MFCJ40 at 628.3 N. The external adjuster is ideal for high-speed changeovers or trial fits where you need to shorten the extend stroke by up to 40 mm on-site without swapping cylinders, while the variable air cushion soaks up end-of-stroke shock.
Remember that the cushion only decelerates the piston near the end of travel—it is not a brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve. This TC trunnion-equipped, magnet-ready (-S) build has no back cover or SDB mount, so plan your pivot and sensor layout accordingly.
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 MFCJ Adjustable Mini Cylinder MFCJ32X100-40STC FAQ
This 32 mm bore cylinder uses a 1/4" port and a male M10x1.25 rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 40 mm (usable range 60-100 mm); retract remains full. The variable air cushion at both ends decelerates the piston near stroke end to reduce shock. The -S magnet enables CMSG, DMSG and EMSG sensors, but neither the cushion nor adjuster acts as a lock to hold the load on air loss.
