Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-75
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-75 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 225mm stroke, 1/8" 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 MFCJ25X225-75
Trim the extend stroke by up to 75 mm on site with this double-acting, variable-cushion JIS-standard round-body mini cylinder. The riveted SUS304 stainless barrel and aluminium covers yield a body notably shorter than an ISO 6432 unit for the same 25 mm bore and 225 mm stroke, saving valuable mounting length while resisting mild washdown.
Delivering 245.3 N push and 206.1 N pull at 0.5 MPa, it handles a safe working load of roughly 147 N. Needle air cushions at both ends soak up high-speed shock. Note this SKU lacks a magnet, so it cannot take a sensor; add the -S variant for CMSG/DMSG/EMSG switches. The 1/8" port and M10x1.25 rod thread simplify integration.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-75 Is Used
Adjustable Tooling Stops
Dial in the extend stroke within the 75 mm window during machine changeovers to set precise tooling endpoints for varying part sizes without swapping cylinders.
High-Speed Diverter Arms
Use the variable air cushion to silently absorb shock at 800 mm/s when deflecting lightweight packages, relying on the 245.3 N push force for positive contact.
Vertical Lift Gates
Lift access panels weighing about 12.5 kg using the 0.5 MPa thrust, tweaking the extend position on-site to match varying door clearances perfectly.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-75 the Right Cylinder?
When sizing this adjustable-cushion series, compare the real thrusts: the 25 mm bore gives 245.3 N push at 0.5 MPa, sitting neatly between the 20 mm bore at 157 N and the 32 mm bore at 402.2 N. Choose the 25 mm bore when you need to lift about 12.5 kg vertically with a 2:1 margin, but step up to 32 mm if changeover loads peak higher.
The 75 mm external adjuster is perfect for trial fits where the exact extend endpoint and end-of-stroke shock both need tuning, operating at speeds of 30-800 mm/s. Remember the cushion only decelerates the piston—it is not a lock. For position holding on air loss, fit an external rod lock or pilot check valve. Mount via LB foot, FA flange or TC trunnion (no SDB). As this specific SKU 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 MFCJ25X225-75 FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, or 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical max of 50 kgf at 1.0 MPa. Operating speed is 30-800 mm/s, and the 225 mm base stroke is non-standard compliant but within the 500 mm max.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant for position sensing. The external adjuster shortens the extend stroke by up to 75 mm, but it only sets the end position; the variable air cushion decelerates the piston near the ends and does not lock or hold the load.
