Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-30S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-30S 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 MFCJ32X225-30S
Tune both the extend end-point and end-of-stroke shock precisely on-site with this 32 mm bore, 225 mm stroke cylinder. The external adjuster shortens the forward stroke by up to 30 mm (usable range 195-225 mm), while the needle-set variable air cushion at both ends soaks up high-speed kinetic energy for smooth deceleration. A built-in magnet (-S) enables CMSG, DMSG or EMSG switches for position sensing.
Built as a JIS-standard round-body mini with a SUS304 stainless barrel and riveted aluminium covers, this unit is shorter than an ISO 6432 cylinder for the same stroke, saving valuable machine space. It pushes with 402.2 N and pulls with 345.6 N at 0.5 MPa via a 1/4" port. For practical sizing, this yields a safe working load of about 241 N, lifting roughly 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-30S Is Used
Adjustable Tooling Stops
Fine-tune the extend stroke up to 30 mm during machine changeovers to accommodate different part lengths, using the 402.2 N push force to position components accurately.
High-Speed Diverting
Deploy the variable air cushion to absorb shock at 800 mm/s when sorting packages on a line, while the -S magnet confirms the divert arm position via sensors.
Vertical Lift Gates
Lift light access gates or guards weighing up to 20.5 kg with a 2:1 safety margin, adjusting the open height on-site without disassembling the cylinder.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-30S the Right Cylinder?
Choose between the two available bores based on your force needs: the MFCJ32 provides 402.2 N push at 0.5 MPa, while the larger MFCJ40 delivers 628.3 N. This 32 mm bore is ideal for medium-duty changeovers where you need to dial in the exact extend position within a 30 mm window without swapping cylinders. The variable air cushion is essential when running at high speeds (30-800 mm/s) to prevent harsh end-of-stroke impacts during trial fits.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover). Remember that the air cushion only decelerates the piston near the end of stroke; it does not lock or hold the load. If air pressure drops, the piston will drift. For suspended or vertical loads, install an external rod lock or pilot-operated 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 MFCJ32X225-30S FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod with an M10x1.25 male thread. It generates 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.
The external adjuster shortens the extend stroke by up to 30 mm on-site (usable range 195-225 mm), but it does not lock the piston mid-stroke. The needle-set variable air cushion at both ends decelerates the piston near the end of travel to reduce shock. Because it includes the -S magnet, you can fit CMSG, DMSG, or EMSG switches for position sensing.
