Airtac MFCJ Adjustable Mini Cylinder MFCJ32X25-30
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X25-30 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MFCJ32X25-30
Tune both travel and end-of-stroke shock precisely with this AirTAC adjustable-stroke mini cylinder. The external adjuster shortens the extend stroke by up to 30 mm on site, while needle variable air cushions at both ends absorb high-speed impact. It features a 32 mm bore, a 12 mm rod, and a 1/4" port.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it is shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length. Delivering 402.2 N push force at 0.5 MPa, it yields a safe working load of roughly 241 N. Note this SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X25-30 Is Used
Probe Positioning
Dial in the exact 0-25 mm extend for electronic test probes, relying on the 241 N safe working load to seat contacts reliably without overshock.
Light Diverter Arms
Tune the divert stroke on a packaging line by up to 30 mm on site, letting the variable air cushion silently absorb 800 mm/s high-speed returns.
Carton Stopper Gates
Adjust the stopping position for varying box sizes on the fly, using the 402.2 N push force to halt lightweight cardboard cartons smoothly.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X25-30 the Right Cylinder?
Choose the 32 mm bore for moderate thrust: it provides 402.2 N push at 0.5 MPa compared to the 628.3 N of the larger MFCJ40, or the 245.3 N of the smaller MFCJ25. The 30 mm adjustable window is perfect for high-speed changeovers or shock-sensitive trial fits where the exact extend position must be dialed in physically. Mount via LB foot, FA flange, or TC trunnion (no SDB or back-cover option exists).
Remember that the air cushion only decelerates the piston near the end of travel; it is not a brake. If the load must be held during air loss, add an external rod lock or pilot check valve. Because this exact model has no -S magnet, position sensing is impossible without switching to the -S variant.
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 MFCJ32X25-30 FAQ
This 32 mm bore cylinder uses a 1/4" port and a 12 mm rod with an M10x1.25 male thread. 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.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. The external adjuster shortens the extend stroke by up to 30 mm on site, while the variable air cushions at both ends decelerate the piston near stroke end to reduce shock.
