Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-75S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-75S 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 MFCJ25X225-75S
Dial in exact extend lengths on-site with the AirTAC MFCJ25X225-75S, a JIS-standard round-body mini cylinder featuring a 75 mm adjustable window and variable air cushions at both ends. The SUS304 stainless steel barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke, while resisting mild washdown corrosion.
Driven by a 1/8" port and a Ø10 mm rod, this double-acting actuator delivers 245.3 N of push force at 0.5 MPa. The integrated needle cushions absorb high-speed end-of-stroke shock, and the -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG position switches. It yields a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-75S Is Used
Adjustable Tooling Stops
Tune the extend position by up to 75 mm during machine changeovers, using the needle cushions to softly settle 12 kg tooling heads without slamming.
High-Speed Diverter Arms
Rely on the 245.3 N push force to swing lightweight routing gates at high cycle rates, with variable air cushions soaking up the end-of-stroke impact.
Variable-Depth Pushers
Set precise carton indexing depths on the fly for mixed SKU lines, leveraging the 1/8" port and JIS compact body to fit tight transfer frames.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-75S the Right Cylinder?
Weigh your thrust needs across the range: the MFCJ20 provides 157 N of push at 0.5 MPa, this MFCJ25 hits 245.3 N, and the larger MFCJ32 outputs 402.2 N. Choose this 25 mm bore when your changeover requires both a tunable 150 to 225 mm extend and smooth deceleration for shock-sensitive trial fits.
Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover here). Remember the air cushion only decelerates the piston near stroke end—it is not a brake. If gravity or air loss could cause the load to drift, fit an external rod lock or pilot check valve. The -S magnet allows solid-state or reed sensors to track the full travel.
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 MFCJ25X225-75S FAQ
This 25 mm bore cylinder uses a 1/8" port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. Its theoretical maximum force is 50 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 75 mm (usable range 150-225 mm), while the variable air cushions at both ends decelerate the piston near the ends for quiet high-speed motion. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
