Airtac MFCJ Adjustable Mini Cylinder MFCJ25X30-30
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X30-30 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 30mm 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 MFCJ25X30-30
Dial in the exact extend end-point on-site with the AirTAC MFCJ25X30-30, a JIS-standard round-body mini cylinder featuring a 30 mm adjustable stroke window. The external adjuster shortens the extend travel by up to 30 mm, while the needle-set variable air cushion at both ends soaks up high-speed shock for smooth deceleration.
Built with a SUS304 stainless barrel and riveted aluminium covers, this double-acting actuator provides 245.3 N of push force at 0.5 MPa through its 1/8" port. It yields a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot accept position switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X30-30 Is Used
Precision Trial Fits
Fine-tune the extend stroke by up to 30 mm during assembly changeovers, using the variable air cushion to softly land 245.3 N of push force without slamming.
High-Speed Diverting
Adjust the end position on the fly for varying package sizes, letting the needle cushion absorb the shock of rapid 30 mm extension movements.
Lab Automation
Set exact reach for testing probes in compact spaces; the SUS304 stainless barrel handles mild washdown while delivering a safe 147 N working load.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X30-30 the Right Cylinder?
When sizing this actuator, compare the real thrust figures: this 25 mm bore gives 245.3 N push at 0.5 MPa, sitting neatly between the smaller MFCJ20 at 157 N and the larger MFCJ32 at 402.2 N. Choose the 25 mm bore when you need that mid-range force in a body that is shorter than a comparable ISO 6432 cylinder, saving valuable mounting length.
The adjustable stroke and dual variable air cushions are ideal for high-speed changeovers and shock-sensitive trial fits. Remember that the cushion only decelerates the piston near the end of travel—it is not a lock or brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve. Also, because this specific SKU has no -S magnet, it cannot support CMSG, DMSG, or EMSG sensors.
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 MFCJ25X30-30 FAQ
This 25 mm bore double-acting cylinder uses a 1/8" air port and a 10 mm rod with an M10x1.25 male thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The external adjuster physically shortens the extend stroke by up to 30 mm, and the variable air cushion handles end-of-stroke deceleration.
