Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-10S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-10S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 225mm 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 MFCJ25X225-10S
Dial in exact end positions on-site with the AirTAC MFCJ25X225-10S, a JIS-standard round-body mini cylinder built from SUS304 stainless steel and riveted aluminium covers. The external adjuster shortens the extend stroke by up to 10 mm (usable range 215-225 mm), while a needle-set variable air cushion at both ends soaks up high-speed end-of-stroke shock for quiet, smooth motion. A 1/8" port feeds the 25 mm bore, generating 245.3 N of push force at 0.5 MPa.
This adjustable-stroke, double-acting actuator features a built-in piston magnet for CMSG/DMSG/EMSG sensors and offers a shorter mounting envelope than an ISO 6432 cylinder for the same stroke. It delivers a safe working load of roughly 147 N (about 60% of its 0.5 MPa push rating), lifting approximately 12.5 kg vertically with a 2:1 margin. Remember that the cushion only decelerates the piston; it does not lock the load if air pressure drops.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-10S Is Used
High-Speed Forming Press
Uses the 245.3 N push force to drive a small forming die, tuning the 10 mm extend window for precise material thickness while the variable air cushion absorbs rapid end-of-stroke shock.
Package Divert Arm
Actuates a routing flap at 30-800 mm/s; the needle cushion halts the 215-225 mm stroke smoothly without slamming, preventing package damage during high-throughput sortation.
Vertical Lift Gate
Lifts a 12.5 kg access panel with a 2:1 safety margin, relying on the external adjuster to set the exact opening height and the cushion to soften the deceleration at the top.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X225-10S the Right Cylinder?
When sizing this series, compare the real thrust figures: the 25 mm bore provides 245.3 N push at 0.5 MPa, sitting neatly between the MFCJ20 at 157 N and the MFCJ32 at 402.2 N. Choose the MFCJ25X225-10S when your application needs precise 215-225 mm extend tuning alongside high-speed shock absorption, as the variable air cushion prevents harsh end-of-stroke impacts during rapid changeovers.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover code). The -S suffix means a magnet is already included for CMSG/DMSG/EMSG switches. Because the cylinder drifts on air loss, install an external rod lock or pilot-operated check valve if you need to hold a suspended load safely in place.
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 MFCJ25X225-10S FAQ
This 25 mm bore cylinder uses a 1/8" air port and delivers 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa with a speed range of 30-800 mm/s.
The external adjuster shortens the extend stroke by up to 10 mm (usable range 215-225 mm), and the needle-set variable air cushion at both ends decelerates the piston near stroke end to reduce shock. The -S suffix enables CMSG/DMSG/EMSG sensors. The cushion is not a brake; the piston will drift on air loss, so use an external rod lock or pilot check valve for load holding.
