Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-20S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-20S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 160mm 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 MFCJ25X160-20S
Dial in the exact extend length on-site with the AirTAC MFCJ25X160-20S, a JIS-standard round-body mini cylinder built from a SUS304 stainless barrel and riveted aluminium covers. The external adjuster lets you shorten the extend stroke by up to 20 mm (yielding a 140-160 mm usable window), while the needle-set variable air cushion at both ends soaks up high-speed end-of-stroke shock. A built-in piston magnet (-S) enables CMSG, DMSG, or EMSG position switches.
Operating at a 245.3 N push force at 0.5 MPa, this double-acting actuator provides a safe working load of roughly 147 N and lifts about 12.5 kg vertically with a 2:1 margin. It runs on a 1/8" air port, features a 10 mm piston rod with an M10x1.25 male thread, and is notably shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length without claiming ISO compliance.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-20S Is Used
Sorter Diverter Tuning
Fine-tune the 140-160 mm extend reach on a high-speed parcel diverter to match varying box sizes, using the needle cushion to halt the 245.3 N thrust smoothly.
Light Press Assembly
Trial-fit small bearings or pins by adjusting the extend stop on the line, letting the air cushion absorb the impact of repeated rapid strokes without slamming.
Carton Flap Folding
Adjust the extend window on the fly for different carton depths, ensuring the flap folds cleanly while the cushion protects the 12.5 kg load capacity at high cycle rates.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-20S the Right Cylinder?
When sizing these adjustable-stroke units, compare the real thrust outputs: this 25 mm bore pushes 245.3 N at 0.5 MPa, sitting neatly between the 20 mm bore (157 N) and the 32 mm bore (402.2 N). Choose the MFCJ25 when you need moderate force for high-speed changeovers or shock-sensitive trial fits where both the end position and the deceleration rate must be tuned independently.
Remember that the air cushion only decelerates the piston near the stroke end—it is not a brake. If the machine loses air, the piston drifts, so fit an external rod lock or pilot check valve to hold a suspended load. For mounting, select LB foot, FA flange, or TC trunnion brackets (SDB and rear covers are unavailable on this 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 MFCJ25X160-20S FAQ
This double-acting cylinder uses a 1/8" air port and generates a push force of 245.3 N and a pull force of 206.1 N at 0.5 MPa. At 0.7 MPa, the push is 343.4 N and the pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 20 mm, giving a usable 140-160 mm window, while the retract remains full length. The variable air cushion at both ends decelerates the piston at high speeds but does not lock the load; the -S suffix means it has a magnet for CMSG/DMSG/EMSG sensors.
