Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-50 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 MFCJ32X300-50
Tune extend travel precisely on-site with the AirTAC MFCJ32X300-50, a JIS-standard round-body mini cylinder built from a riveted aluminium cover and SUS304 stainless steel barrel. The external adjuster shortens the extend stroke by up to 50 mm, while the variable air cushion at both ends soaks up high-speed shock for smooth deceleration.
Delivering 402.2 N push force at 0.5 MPa through a 1/4" port, this double-acting unit yields a safe working load of roughly 241 N. It is shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. Note this SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-50 Is Used
High-Speed Component Pressing
Dial in the exact 250-300 mm extend position and use the needle air cushion to absorb impact when pressing light assemblies at high speed.
Adjustable Transfer Diverter
Fine-tune the diverter stroke by up to 50 mm during product changeovers, relying on the 241 N safe working load to redirect packages smoothly.
Dynamic Carton Forming Stop
Set the precise carton width stop on the fly and let the variable air cushion quietly decelerate the 402.2 N thrust at the end of every cycle.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-50 the Right Cylinder?
When sizing these adjustable cylinders, weigh the MFCJ32 against the MFCJ40. The 32 mm bore provides 402.2 N of push force at 0.5 MPa, whereas the larger MFCJ40 delivers 628.3 N. If your changeover requires less than 245.3 N, a smaller MFCJ25 would suffice, but this 32 mm bore offers a strong middle ground. The 50 mm adjust window is perfect for trial fits where the exact end position and end-of-stroke shock both need dialing in.
Mounting options include LB foot, FA flange and TC trunnion (no SDB or back-cover code is available). Because this specific SKU has no -S magnet, position sensing is not possible without switching to the -S variant. Remember that the air cushion only decelerates the piston near the end of travel; it does not lock or hold the load. If you need to prevent drift 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 MFCJ32X300-50 FAQ
This 32 mm bore double-acting cylinder features a 1/4" port and a 12 mm rod. 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.
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 external adjuster shortens the extend stroke by up to 50 mm, and the variable air cushion handles end-of-stroke deceleration, but neither acts as a mid-stroke lock.
