Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-100
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-100 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 225mm 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 MFCJ32X225-100
Dial in your extend distance on-site with the AirTAC MFCJ32X225-100, a JIS-standard round-body mini cylinder built from SUS304 stainless steel and riveted aluminium covers. The external adjuster shortens the nominal 225 mm extend stroke by up to 100 mm, yielding a usable 125-225 mm window, while a needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock. Retract remains full length, and the 1/4" port feeds a 12 mm rod to deliver 402.2 N of push force at 0.5 MPa.
This compact body is shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length without claiming ISO compliance. The SUS304 barrel resists mild corrosion and washdown environments. For sizing, expect a safe working load around 241 N (60% of the 0.5 MPa push force), lifting about 20.5 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-100 Is Used
High-Speed Forming Press
Tune the 125-225 mm extend stroke on the fly for part changeovers, relying on the variable air cushion to absorb the 402.2 N push impact at rapid cycle speeds.
Dynamic Divert Gate
Adjust the extend endpoint precisely to route varying package sizes, while the needle cushion ensures quiet, shock-free stops despite the 30-800 mm/s operating speed.
Vertical Lift Station
Lift loads up to 20.5 kg with a 2:1 safety margin, using the 100 mm adjuster to set exact raise heights without repositioning the cylinder mounts.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-100 the Right Cylinder?
When choosing between the two available bores, the MFCJ32 delivers 402.2 N push at 0.5 MPa, whereas stepping up to the MFCJ40 provides 628.3 N. This 32 mm bore is ideal for moderate loads where you need both on-site stroke tuning and high-speed deceleration. The 100 mm adjustable window is perfect for changeovers requiring precise extend positioning without machining new stops.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover code applies here). Remember that the air cushion only decelerates the piston near stroke end—it is not a lock or brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve. Because this specific SKU has no -S magnet, you cannot mount position sensors; order the -S variant if you require CMSG, DMSG, or 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 MFCJ32X225-100 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, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. The nominal 225 mm stroke can be shortened by up to 100 mm on the extend end.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. You must order the -S variant for sensing capabilities. Additionally, the external adjuster only sets the extend end position; it does not function as a mid-stroke lock.
