Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-75
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-75 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 MFCJ25X100-75
Trim the extend end by up to 75 mm on site with this adjustable-stroke, variable-cushion mini cylinder. The JIS-standard riveted SUS304 stainless body and aluminium covers form a double-acting actuator shorter than an ISO 6432 unit, saving valuable mounting length while resisting mild washdown.
Delivering 245.3 N push at 0.5 MPa through a 1/8" port, it handles a safe working load near 147 N. The needle air cushion at both ends decelerates high-speed motion smoothly; note this base SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-75 Is Used
High-Speed Probe Testing
Dial in the exact 25-100 mm extend contact point and use the needle cushion to absorb the 245.3 N impact during rapid electronic probe cycling.
Adjustable Package Diverter
Fine-tune the pusher stroke on the fly for mixed carton sizes while the variable air cushion ensures quiet, shock-free stops at 800 mm/s.
Lab Automation Stopper
Set a precise specimen stop within the 75 mm window; the SUS304 barrel withstands mild cleaning agents in laboratory environments.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-75 the Right Cylinder?
When sizing, compare this 25 mm bore offering 245.3 N @0.5 MPa against the MFCJ20 at 157 N for lighter duties, or step up to the MFCJ32 at 402.2 N if you need more thrust. The 75 mm adjustable window is ideal for high-speed changeovers where exact end positions and shock tuning must be set on the machine.
Mount via LB foot, FA flange, or TC trunnion (no SDB). Remember the cushion only decelerates near stroke end—it is not a lock; for holding a load on air loss, fit 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 MFCJ25X100-75 FAQ
This double-acting cylinder uses a 1/8" port and generates 245.3 N push / 206.1 N pull @0.5 MPa, 343.4 N push / 288.5 N pull @0.7 MPa, with a theoretical max of 50 kgf @1.0 MPa. It features a Ø10 mm rod with an M10x1.25 male thread.
No, this specific SKU lacks the internal magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The 75 mm adjuster only shortens the extend stroke, and the variable air cushion decelerates motion but does not lock the load.
