Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-100
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-100 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 MFCJ32X250-100
Trim the extend stroke by up to 100 mm on site and dial in a needle air cushion at each end to absorb high-speed shock. This double-acting JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, giving you a 150 to 250 mm usable extend window from the 250 mm base stroke.
Operating at 0.15-1.0 MPa on a 1/4" port with a 12 mm rod, it delivers 402.2 N of push force at 0.5 MPa. The riveted construction is shorter than an ISO 6432 cylinder for the same envelope, saving valuable mounting length. This SKU lacks the -S magnet, so it cannot take CMSG, DMSG, or EMSG sensors. Expect a safe working load around 241 N, lifting about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-100 Is Used
Adjustable Press Fit
Dial in the exact 150 to 250 mm extend distance for delicate press-fit operations, relying on the 402.2 N push force and needle cushion to prevent impact damage.
High-Speed Diverting
Fine-tune the stroke length on a diverter arm during product changeovers, using the adjustable air cushion to smoothly stop the 12 mm rod at high cycle rates.
Lab Automation Jig
Set up trial positions on a testing jig where the exact extend endpoint varies, leveraging the 241 N safe working load for precise component loading.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-100 the Right Cylinder?
When sizing these adjustable-stroke units, compare the real thrust: the MFCJ32 bore provides 402.2 N push at 0.5 MPa, while stepping up to the MFCJ40 yields 628.3 N. Choose the 32 mm bore for lighter, high-speed changeovers where shock-sensitive trial fits demand precise end-position tuning via the 100 mm window and variable air cushion.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover code). Remember that the air cushion only decelerates the piston near stroke end; it is not a lock. If your application must hold a load on air loss, add an external rod lock or pilot check valve. Because this specific code has no -S magnet, position sensing is unavailable.
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 MFCJ32X250-100 FAQ
This 32 mm bore cylinder uses 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.
The external adjuster shortens the extend stroke by up to 100 mm, giving a 150 to 250 mm usable window. The variable air cushion at both ends decelerates the piston near the end of travel for smooth stops. Note this SKU lacks the -S magnet, so it cannot accept position sensors.
