Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-50S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-50S 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 MFCJ25X160-50S
Dial in exact extend distances on-site with the AirTAC MFCJ25X160-50S, a JIS-standard round-body mini cylinder offering a 50 mm stroke reduction window from its 160 mm nominal length. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG reed or electronic switches for position confirmation. A variable air cushion at both ends soaks up high-speed kinetic energy, ensuring smooth deceleration rather than harsh end-of-stroke impacts.
Featuring a SUS304 stainless steel barrel and riveted aluminium covers, this double-acting actuator runs at 30-800 mm/s with a 1/8" port and an M10x1.25 male rod thread. Delivering 245.3 N of push force at 0.5 MPa, it yields a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 margin. The riveted body is shorter than a comparable ISO 6432 cylinder, saving valuable mounting length without claiming ISO compliance.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-50S Is Used
Adjustable Tooling Stops
Fine-tune the extend position up to 50 mm on machining fixtures to accommodate part variations without swapping cylinders, leveraging 245.3 N of push force.
High-Speed Diverters
Use the variable air cushion to silently absorb end-of-stroke shock during rapid package sorting tasks, preventing premature wear on conveyor mechanisms.
Vertical Lift Gates
Lift light access panels or dividers up to 12.5 kg vertically, confirming full extension via DMSG sensors enabled by the integrated piston magnet.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X160-50S the Right Cylinder?
When sizing this actuator, compare the real thrust figures: this 25 mm bore generates 245.3 N push at 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 your changeover requires precise extend tuning within the 110-160 mm usable range alongside moderate force. The external adjuster sets the end position but does not lock mid-stroke.
Because the needle air cushion only decelerates the piston near the end caps and never acts as a brake, a plain cylinder will drift if air pressure drops. To hold a vertical load securely during air loss or valve centering, integrate an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, and TC trunnion (no SDB), and the -S magnet allows seamless sensor integration.
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 MFCJ25X160-50S FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod 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 50 mm on-site, yielding a usable extend range of 110-160 mm, while the retract stroke remains full. The variable air cushion at both ends uses a needle valve to decelerate the piston smoothly at high speeds, but it is not a locking brake; the -S magnet enables CMSG, DMSG, and EMSG sensors.
