Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-100S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-100S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MFCJ25X100-100S
Dial in exact extend distances and soak up high-speed shock with the AirTAC MFCJ25X100-100S. This JIS-standard round-body mini cylinder features a 100mm adjustable stroke window and needle-set variable air cushions at both ends. The SUS304 stainless barrel shrinks mounting length compared to an ISO 6432 unit and resists mild washdown corrosion.
Driven by a 1/8" port and Ø10mm rod, the 25mm bore yields 245.3N push and 206.1N pull at 0.5MPa. That translates to a safe working load near 147N, lifting about 12.5kg vertically with a 2:1 margin. The -S suffix adds a piston magnet for CMSG/DMSG/EMSG position sensing.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-100S Is Used
High-Speed Forming Press
Tune the 100mm extend window to set precise ejection depth while the needle air cushion absorbs end-of-stroke impact during rapid 245N push cycles.
Transfer Diverters
Adjust the stroke on-site to match varying package sizes, relying on the 12.5kg vertical lift capacity and smooth cushioned deceleration.
Pallet Stops
Shorten the extend position for mixed pallet heights; the SUS304 body handles dusty environments and the -S magnet tracks stop confirmation.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-100S the Right Cylinder?
Compare the bores before buying: the MFCJ20 delivers 157N at 0.5MPa, this MFCJ25 hits 245.3N, and the MFCJ32 jumps to 402.2N. Choose the 25mm bore when your fixture needs mid-range thrust plus on-site extend tuning. The 100mm adjuster window lets you perfect the end position during changeovers without machining spacers.
Mount via LB foot, FA flange, or TC trunnion (no SDB). The variable air cushion decelerates the piston near stroke end but does not lock the load—add an external rod lock or pilot check valve if air loss must not cause drift. CMSG/DMSG/EMSG switches snap onto the -S magnet groove.
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 MFCJ25X100-100S FAQ
It has a 1/8" port and a Ø10mm rod. Thrust is 245.3N push / 206.1N pull at 0.5MPa, and 343.4N push / 288.5N pull at 0.7MPa. The theoretical max force is 50kgf at 1.0MPa.
No. The variable air cushion only decelerates the piston near the end of stroke; it is not a brake. The cylinder drifts on air loss. The 100mm external adjuster sets the extend end position but does not lock mid-stroke. The -S magnet enables CMSG/DMSG/EMSG sensors.
