Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-75
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-75 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 MFCJ25X200-75
Trim the extend stroke by up to 75 mm on site with the AirTAC MFCJ25X200-75, a JIS-standard round-body mini cylinder built for high-speed changeovers. The riveted SUS304 stainless barrel and aluminium covers form a compact body that is shorter than an ISO 6432 unit for the same 200 mm stroke, while the needle-set variable air cushion at both ends soaks up end-of-stroke shock.
Delivering 245.3 N of push force at 0.5 MPa through a 1/8" port, this double-acting actuator yields a safe working load of about 147 N. It lifts roughly 12.5 kg vertically with a 2:1 margin. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-75 Is Used
Sorter Diverter Tuning
Dial in the exact 125 to 200 mm extend reach for a parcel diverter arm during line speed changes, relying on the variable air cushion to absorb the impact of fast redirects.
Carton Flap Plow
Adjust the stroke end on the fly to match varying carton depths, using the 245.3 N push force to fold heavy cardboard flaps smoothly at high cycle rates.
Light Press Fit
Set the precise extend position for seating delicate bearings, letting the needle cushion decelerate the 147 N safe working load gently before contact.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-75 the Right Cylinder?
When sizing this series, compare the real thrust outputs: the 25 mm bore provides 245.3 N of push at 0.5 MPa, sitting neatly between the 157 N of an MFCJ20 and the 402.2 N of an MFCJ32. Choose the 25 mm bore when your application demands that middle force band alongside a tunable 125 to 200 mm extend window. The external adjuster sets the end position but does not lock the piston mid-stroke.
The variable air cushion only decelerates the load near the stroke ends; it is not a brake. If your setup must hold a load vertically during an air loss or valve shift, the piston will drift, so you must fit an external rod lock or pilot-operated check valve. For mounting, select LB foot, FA flange or TC trunnion brackets, as there is no SDB or back-cover option on this adjustable build.
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 MFCJ25X200-75 FAQ
This 25 mm bore cylinder uses a 1/8" 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.
This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG magnetic switches. The external adjuster shortens the extend stroke by up to 75 mm from the 200 mm maximum, while the variable air cushion at both ends decelerates the piston to reduce shock.
