Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-40S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-40S 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 MFCJ25X160-40S
Tune both the extend reach and the end-of-travel shock on site with this double-acting mini cylinder. The external adjuster lets you shorten the nominal 160 mm extend stroke by up to 40 mm, while the needle variable air cushion at both ends soaks up high-speed impact for smooth deceleration. A built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing.
Built to JIS standard with a SUS304 stainless barrel and riveted aluminium covers, the riveted round-body construction is shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length. Delivering 245.3 N push force at 0.5 MPa through a 1/8" port, it yields a safe working load of about 147 N. With a 2:1 safety margin, it lifts about 12.5 kg vertically, making it ideal for changeovers where exact positioning and shock absorption need fine-tuning.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-40S Is Used
High-Speed Component Pressing
Use the 40 mm extend adjuster to set the exact 120-160 mm contact depth on delicate assemblies, relying on the variable air cushion to decelerate the 245.3 N push force smoothly without slamming.
Changeover Diverter Gates
Fine-tune the diverting stroke length on the fly during product changeovers. The CMSG sensor confirms the adjusted extend position, while the cushion absorbs shock from high-speed 800 mm/s actuation.
Variable-Depth Carton Sealing
Adapt to different carton heights by shortening the extend stroke up to 40 mm. The SUS304 stainless barrel resists washdown, and the 147 N safe working load handles light packaging flaps securely.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-40S the Right Cylinder?
When sizing this adjustable-stroke family, compare the real thrust figures: the 25 mm bore offers 245.3 N push at 0.5 MPa, stepping up to 402.2 N for the MFCJ32, or down to 157 N for the MFCJ20. Choose the 25 mm bore when your application needs that middle force band with on-site stroke and cushion tuning for high-speed trial fits.
Mounting options include LB foot, FA flange and TC trunnion (there is no SDB or back-cover option on this build). The -S magnet enables CMSG, DMSG or EMSG sensors. Note that the air cushion only decelerates the piston near the stroke end and the adjuster sets the end position; neither acts as a lock. If you need to hold a load on air loss, add an external rod lock or pilot-operated 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 MFCJ25X160-40S FAQ
This 25 mm bore cylinder features a 1/8" air 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 force of 50 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 40 mm (usable range 120-160 mm), and the needle variable air cushion decelerates the piston at both ends. The cushion is not a brake or lock; the cylinder cannot hold a load on air loss. The -S suffix means a magnet is built in for CMSG, DMSG or EMSG sensors.
