Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-40
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-40 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MFCJ32X250-40
Dial in exact end positions and absorb high-speed shock with the AirTAC MFCJ32X250-40, a JIS-standard round-body mini cylinder. The external adjuster shortens the extend stroke by up to 40 mm on site, while the needle variable air cushion at both ends soaks up end-of-stroke impact. This 32 mm bore unit pushes 402.2 N at 0.5 MPa, yielding a safe working load around 241 N or a 20.5 kg vertical lift with a 2:1 margin.
Built with a SUS304 stainless barrel and riveted aluminium covers, it resists mild corrosion and washdown. It is shorter than an ISO 6432 cylinder for the same bore and stroke, saving mounting length. This SKU lacks the -S magnet, so it cannot take CMSG/DMSG/EMSG sensors. Air enters via a 1/4" port, and the 12 mm rod uses an M10x1.25 male thread.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-40 Is Used
Machine Tool Changeover
Tune the 250 mm extend stroke within its 40 mm window to strike parts precisely, using the variable air cushion to halt the 402.2 N thrust smoothly.
High-Speed Diverting
Divert packages at speed; the needle cushion absorbs the shock of rapid stops while the adjuster fine-tunes the pusher reach on site.
Carton Forming Stops
Set exact forming depths during format changes. The SUS304 barrel handles light washdown, and the 241 N safe working load manages flaps easily.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-40 the Right Cylinder?
Choose MFCJ32 for moderate thrust needs, pushing 402.2 N at 0.5 MPa. If your changeover requires more power, step up to the MFCJ40 at 628.3 N; if loads are lighter, the MFCJ25 provides 245.3 N. The 40 mm adjustable window here is perfect for trial fits where the exact extend endpoint and end-of-stroke shock both need tuning. Mount using LB foot, FA flange, or TC trunnion (no SDB or back-cover). Note that the cushion only decelerates and the adjuster sets the endpoint; neither holds the load. For position holding on air loss, install an external rod lock or pilot 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 MFCJ Adjustable Mini Cylinder MFCJ32X250-40 FAQ
This 32 mm bore cylinder uses a 1/4" port. 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.
This specific SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG sensors. The external adjuster shortens the extend stroke by up to 40 mm from the 250 mm maximum; it sets the endpoint and is not a mid-stroke lock.
