Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-40
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-40 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MFCJ32X300-40
Tune both the extend end-point and end-of-stroke shock on site with this AirTAC adjustable-stroke mini cylinder. The external adjuster shortens the extend stroke by up to 40 mm (usable range 260-300 mm), while the needle variable air cushion at both ends soaks up high-speed kinetic energy for smooth deceleration. It is a JIS-standard round-body build with a SUS304 stainless barrel and riveted aluminium covers, engineered to be shorter than an ISO 6432 cylinder for the same bore and stroke to save mounting length.
Fitted with a 12 mm rod and a 1/4" port, this double-acting 32 mm bore generates 402.2 N push and 345.6 N pull at 0.5 MPa. That equates to a safe working load of roughly 241 N, or lifting about 20.5 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot take CMSG/DMSG/EMSG sensors; there is no back-cover or SDB mount on this adjustable build.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-40 Is Used
Sorter Diverter Tuning
Dial in the 260-300 mm extend reach on a high-speed parcel diverter using the 40 mm adjuster, while the variable air cushion absorbs the shock of deflecting heavy boxes.
Carton Flap Folding
Adjust the push stroke on the fly during carton size changeovers, relying on the 402.2 N push force to fold heavy cardboard flaps smoothly without end-of-stroke slamming.
Pallet Stopper Gate
Act as a shock-absorbing pallet stop gate where the 241 N safe working load handles moderate pallet resistance, and the needle cushion softens the 800 mm/s high-speed impact.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-40 the Right Cylinder?
Size by force and space: the 32 mm bore gives 402.2 N push at 0.5 MPa, sitting between the MFCJ25 at 245.3 N and the MFCJ40 at 628.3 N. Choose this 32 mm option when you need moderate push force in a compact envelope. The 40 mm adjustable window is perfect for high-speed changeovers or trial fits where the exact 260-300 mm extend position and the cushion needle both need field tuning. Mount via LB foot, FA flange, or TC trunnion.
Remember the air cushion only decelerates the piston near stroke end; it is not a lock or brake. A plain cylinder will drift and drop its load on air loss or when the valve is centred. To hold a vertical load safely, add an external rod lock or a pilot-operated check valve. Because this exact SKU has no -S magnet, you cannot mount magnetic sensors; order the -S variant if you need position feedback.
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 MFCJ32X300-40 FAQ
This 32 mm bore double-acting cylinder has a 1/4" port and a 12 mm rod. It delivers 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 force of 82 kgf at 1.0 MPa.
No. This specific SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG switches. The variable air cushion only decelerates the piston near stroke end and does not act as a lock or brake; the piston will drift on air loss. Use an external rod lock or pilot check valve to hold a load.
