Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-75S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-75S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MFCJ32X250-75S
Trim the extend stroke by up to 75 mm on site and dial in a needle air cushion at each end with the AirTAC MFCJ32X250-75S. This double-acting JIS-standard round-body mini cylinder pairs a 1/4" ported SUS304 stainless barrel with riveted aluminium covers, yielding a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke.
Driven by a Ø12 mm rod (M10x1.25 male thread), it delivers 402.2 N of push force at 0.5 MPa while safely lifting about 20.5 kg vertically with a 2:1 margin. The built-in -S magnet supports CMSG, DMSG, and EMSG switches for position sensing across the 175-250 mm usable extend range.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-75S Is Used
Sorting Diverter
Tunes the 175-250 mm extend stroke on the fly to deflect parcels of varying sizes on a high-speed conveyor belt without slamming.
Press Fit Stand
Provides 402.2 N of push at 0.5 MPa to seat light components, using the variable air cushion to prevent impact damage at rapid cycle rates.
Pallet Stopper
Halts incoming pallets on a washdown-resistant SUS304 barrel, absorbing kinetic energy smoothly via the dual needle cushions.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-75S the Right Cylinder?
When sizing a 32 mm bore against the 40 mm option, the MFCJ32 supplies 402.2 N push at 0.5 MPa versus 628.3 N for the MFCJ40, making this model the better fit for moderate loads under 241 N. Choose the 40 mm bore if your application exceeds that safe working load threshold.
The 75 mm adjustable window is invaluable for high-speed changeovers where the exact end position and end-of-stroke shock both require tuning. Mount via LB foot, FA flange, or TC trunnion (no SDB or back-cover), and remember the cushion only decelerates the piston—it will not hold the load on air loss, so add an external rod lock or pilot check valve if drift is unacceptable.
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 MFCJ32X250-75S FAQ
It features a 1/4" air port and a Ø12 mm rod. The double-acting thrust is 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.
An external adjuster shortens the extend stroke by up to 75 mm (usable range 175-250 mm), while the needle variable air cushion at both ends decelerates the piston for smooth stops. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
