Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-75S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-75S 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 MFCJ32X225-75S
Dial in exact extend lengths on the factory floor with the AirTAC MFCJ32X225-75S, a JIS-standard round-body mini cylinder featuring a 75 mm adjustable stroke window and variable air cushions at both ends. The external adjuster shortens the extend stroke down from a 225 mm maximum, while the needle cushions soak up high-speed end-of-travel shock for smooth, quiet motion. Built with a SUS304 stainless steel barrel and riveted aluminium covers, this double-acting actuator resists mild corrosion and washdown. It also features a 1/4" port and a built-in piston magnet (-S) for position sensing.
Delivering a push force of 402.2 N at 0.5 MPa, this 32 mm bore cylinder provides a safe working load of roughly 241 N. It lifts about 20.5 kg vertically with a 2:1 safety margin. For the same bore and stroke, this compact MF body is shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that standard. The cushion only decelerates the piston near the stroke end; it is not a lock or brake, so the load will drift if air pressure is lost.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-75S Is Used
High-Speed Diverting
Tune the 75 mm extend window to hit moving cartons precisely, relying on the variable air cushion to stop the 402.2 N push force smoothly at 800 mm/s.
Variable Depth Sealing
Adjust the extend end on the fly for different box sizes; the needle cushion absorbs shock so the SUS304 body handles washdown cycles reliably.
Trial-Fit Clamping
Dial in the exact clamping travel during machine changeovers, using the built-in magnet to confirm the adjusted end position without over-stroking.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-75S the Right Cylinder?
When sizing an adjustable-stroke cylinder, compare the real thrust: the 32 mm bore here pushes 402.2 N at 0.5 MPa, whereas the larger MFCJ40 delivers 628.3 N, and the smaller MFCJ25 provides 245.3 N. Choose the 32 mm bore for mid-range tasks where you need to trim the extend position by up to 75 mm on site and tune the end-of-stroke shock during high-speed changeovers or shock-sensitive trial fits.
Because the -S magnet is present, you can mount CMSG, DMSG, or EMSG reed or electronic switches directly to the body. Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover mount is available). To hold a load securely on air loss, add an external rod lock or pilot-operated check valve, as the air cushion acts only as a decelerator.
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 MFCJ32X225-75S FAQ
This double-acting cylinder has a 1/4" port and a 12 mm rod. It pushes 402.2 N and pulls 345.6 N at 0.5 MPa. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 75 mm from the 225 mm maximum; it sets the end position but does not lock mid-stroke. Needle air cushions at both ends decelerate the piston near the ends for high-speed operation. The -S suffix means a magnet is included for CMSG, DMSG, or EMSG sensors.
