Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-30S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-30S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 200mm 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 MFCJ25X200-30S
Dial in exact extend lengths and absorb end-of-stroke shock with the AirTAC MFCJ25X200-30S. This JIS-standard round-body mini cylinder features a 30mm adjustable window, letting you shorten the extend stroke on-site from 200mm down to 170mm, while the retract remains full length. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing.
Constructed with a SUS304 stainless barrel and riveted aluminium covers, it offers mild corrosion resistance and a footprint shorter than an ISO 6432 cylinder for the same bore. Delivering 245.3N push force at 0.5MPa via a 1/8" port, it yields a safe working load of roughly 147N. The variable air cushion at both ends decelerates high-speed motion smoothly.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-30S Is Used
High-Speed Diverting
Tune the 170-200mm extend stroke and set the needle cushion to gently push lightweight packages off a belt without harsh impacts.
Tooling Trial Fits
Perfect for prototyping stations where the exact 245.3N push endpoint must be dialed in on-site during changeovers to avoid crushing delicate parts.
Vertical Lift Stops
Lifts about 12.5 kg vertically with a 2:1 margin; use the external adjuster to set precise upper travel limits for stacker mechanisms.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-30S the Right Cylinder?
When sizing this 25mm bore, compare it directly: the MFCJ20 provides 157N push at 0.5MPa, while the MFCJ32 jumps to 402.2N. The MFCJ25X200-30S hits the middle ground with 245.3N. Choose this adjustable-stroke, variable-cushion model for high-speed changeovers or shock-sensitive trial fits where you need to tune both the extend end-point and the deceleration needle. Mounting options include LB foot, FA flange, or TC trunnion (no SDB). Remember that the air cushion only decelerates; it does not lock. If you need to hold a vertical load on air loss, add an external rod lock or pilot check valve.
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 MFCJ25X200-30S FAQ
This 25mm bore cylinder uses a 1/8" port and a 10mm rod with M10x1.25 male thread. It generates 245.3N push and 206.1N pull at 0.5MPa, 343.4N push and 288.5N pull at 0.7MPa, with a theoretical max of 50 kgf at 1.0MPa.
The external adjuster shortens the extend stroke by up to 30mm (usable range 170-200mm), while the variable air cushion at both ends decelerates the piston near stroke end. The -S suffix means it includes a magnet for CMSG/DMSG/EMSG sensors.
