Airtac MFCJ Adjustable Mini Cylinder MFCJ25X150-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X150-50 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MFCJ25X150-50
Dial in exact end positions on-site with the AirTAC MFCJ25X150-50, a JIS-standard round-body mini cylinder featuring a 50 mm adjustable extend window (usable extend 100-150 mm) and variable air cushions at both ends. The riveted SUS304 stainless barrel and aluminium covers yield a body notably shorter than an ISO 6432 unit for the same 25 mm bore and 150 mm stroke, saving mounting length while resisting mild washdown corrosion.
Operating at 30-800 mm/s on a 1/8" port with a Ø10 mm rod (M10x1.25 male thread), it delivers 245.3 N push and 206.1 N pull at 0.5 MPa. This translates to a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG position switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X150-50 Is Used
Adjustable Tooling Stops
Fine-tune the extend stroke by up to 50 mm during machine changeovers, using the needle cushion to softly stop 12 kg tooling heads running at high speed.
Dynamic Diverter Gates
Set precise gate extension lengths on the fly for varying package sizes, relying on the 245.3 N push force to swing arms without end-of-stroke slamming.
Trial Fit Pushers
Dial in the exact push distance during packaging line commissioning, absorbing high-speed shocks with the variable air cushion while finding the optimal stroke.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X150-50 the Right Cylinder?
When sizing adjustable-stroke actuators, compare the real thrust: this 25 mm bore gives 245.3 N push @0.5 MPa, sitting neatly between the smaller MFCJ20 at 157 N and the larger MFCJ32 at 402.2 N. Choose the 25 mm bore when driving lighter high-speed changeover tooling where you need both a 50 mm extend adjustment and needle-set air cushions to soak up end-of-stroke shock.
Mount via LB foot, FA flange, or TC trunnion (no SDB or back-cover option exists on this build). Because this specific SKU has no -S magnet, you must use external limit switches for positioning. Remember the air cushion only decelerates the piston near stroke end—it is not a lock; for fail-safe 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 MFCJ25X150-50 FAQ
This 25 mm bore cylinder uses a 1/8" port and generates 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.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for internal sensing. The 50 mm external adjuster shortens the extend stroke, while the variable air cushion handles deceleration.
