Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-10
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-10 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 80mm 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 MFCJ32X80-10
Dial in the exact extend stop on-site with the AirTAC MFCJ32X80-10, a JIS-standard round-body mini cylinder featuring a 10 mm adjustable stroke window (usable extend 70-80 mm). The external needle shortens the forward end, while a variable air cushion at both ends soaks up high-speed shock for smooth deceleration. It uses a 1/4" port and a 12 mm rod with an M10x1.25 male thread.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, this double-acting actuator resists mild corrosion and washdowns while saving mounting length compared to an ISO 6432 unit. It pushes with 402.2 N at 0.5 MPa, yielding a safe working load of roughly 241 N or a 20.5 kg vertical lift with a 2:1 margin. Note this non-magnet SKU cannot take a sensor; adding the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-10 Is Used
High-Speed Component Pressing
Tune the 10 mm extend window to set the exact 75 mm contact depth for pressing bearings, using the variable air cushion to absorb the 402.2 N end-of-stroke impact safely.
Adjustable Transfer Diverter
Dial in the diverter arm position on the fly during product changeovers, relying on the 241 N safe working load to push lightweight cartons without slamming.
Delicate Flap Folding
Fine-tune the folding stroke within the 70-80 mm range for various box sizes, letting the needle cushion decelerate the 12 mm rod smoothly before it touches the flap.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-10 the Right Cylinder?
Choose the MFCJ32 (402.2 N push @0.5 MPa) for standard clamping, or step up to the MFCJ40 (628.3 N) if your payload exceeds the 241 N safe working load. Conversely, lighter duties might use the MFCJ25 at 245.3 N. The 10 mm adjustable window and twin air cushions excel in high-speed changeovers where trial fits demand precise end-position tuning without swapping cylinders.
Mount via LB foot, FA flange, or TC trunnion (no SDB or back-cover here). Remember the cushion only decelerates the piston near stroke end—it is not a lock. If air pressure drops, the rod drifts; for suspended loads, install an external rod lock or pilot check valve. Finally, because this exact SKU lacks the -S magnet, it cannot accept CMSG/DMSG/EMSG 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 MFCJ Adjustable Mini Cylinder MFCJ32X80-10 FAQ
This 32 mm bore cylinder uses a 1/4" port and delivers a push force of 402.2 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The 10 mm adjustable stroke window and variable air cushion function independently of the magnet.
