Airtac MFCJ Adjustable Mini Cylinder MFCJ25X50-10S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X50-10S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 50mm 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 MFCJ25X50-10S
Dial in exact extend distances on-site with this double-acting, adjustable-stroke mini cylinder, featuring a 10 mm shortening window for a usable 40-50 mm extend. The JIS-standard riveted round-body construction pairs a SUS304 stainless barrel with aluminium covers, yielding a mounting envelope shorter than an ISO 6432 unit for the same bore and stroke.
Driven by a 1/8" air port and Ø10 mm rod, the bore delivers 245.3 N of push force at 0.5 MPa. Needle-set variable air cushions at both ends absorb high-speed end-of-stroke shock, and the built-in magnet (-S) supports CMSG, DMSG or EMSG switches. Factoring a 2:1 safety margin, it lifts about 12.5 kg vertically.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X50-10S Is Used
Actuator Trial Fitting
Perfect for prototyping stations where the 10 mm extend adjuster lets you find the exact 40-50 mm push position for a new 12.5 kg jig without machining spacers.
High-Speed Diverting
Use the needle variable air cushion to silently stop the 245.3 N extend stroke at high cycle rates, preventing shock damage to lightweight packaging transfers.
Compact Lift Stations
Leverage the SUS304 stainless round-body design and shorter-than-ISO-6432 length to fit precise vertical lifts in tight, washdown-prone dispatch machinery.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X50-10S the Right Cylinder?
Weigh this 25 mm bore against adjacent sizes: the MFCJ20 yields 157 N of push force at 0.5 MPa, while the MFCJ32 jumps to 402.2 N. This model sits in the middle, offering a safe working load of roughly 147 N (60% of its 245.3 N push rating). Choose it when your changeover requires both exact end-position tuning and high-speed deceleration.
Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover option exists on this adjustable build). The -S magnet enables position sensing, but remember the air cushion only decelerates the piston—it does not lock. For load holding on air loss, install 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 MFCJ25X50-10S FAQ
This 25 mm bore cylinder features a 1/8" air port and delivers a push force of 245.3 N and pull of 206.1 N at 0.5 MPa. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external adjuster shortens the extend stroke by up to 10 mm on-site (usable range 40-50 mm), while the retract stroke remains full. The -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The variable air cushion only decelerates the load; it does not hold position on air loss.
