Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-50 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MFCJ25X100-50
Dial in exact end positions and absorb high-speed shock with the AirTAC MFCJ25X100-50 adjustable-stroke cylinder. This JIS-standard round-body mini features an external adjuster that shortens the extend stroke by up to 50 mm on-site, giving a usable 50-100 mm extend window while retract remains full. A needle variable air cushion at both ends soaks up end-of-stroke impact for smooth deceleration.
Built with a SUS304 stainless barrel and riveted aluminium covers, the body is deliberately 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, it yields a safe working load of about 147 N or roughly 12.5 kg vertical lift with a 2:1 margin. The 1/8" port and Ø10 mm rod suit compact changeovers, though this non-magnet SKU cannot take a sensor.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-50 Is Used
Probe Stroke Tuning
Fine-tune the 50-100 mm extend on test fixtures to find the exact contact point without remachining stops, relying on the 245.3 N push force for consistent probing.
High-Speed Diverting
Absorb rapid end-of-stroke shock on sorting pushes using the variable air cushion, preventing impact damage while adjusting the extend length on the fly.
Carton Flap Folding
Set precise fold depths for varying box sizes via the external adjuster, letting the 147 N safe working load handle light packaging materials smoothly.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-50 the Right Cylinder?
When sizing this series, compare the real thrust: the MFCJ20 provides 157 N push at 0.5 MPa, this MFCJ25 hits 245.3 N, and the larger MFCJ32 delivers 402.2 N. Choose the 25 mm bore when you need moderate force in a tight footprint. The 50 mm adjustable window is ideal for trial fits where the exact extend point and end-of-stroke shock both need field tuning.
Remember the air cushion only decelerates the piston near the end of travel; it is not a brake. If the machine loses air, the load will drift, so fit an external rod lock or pilot check valve for position holding. Mount via LB foot, FA flange, or TC trunnion (no SDB). Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG switches.
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 MFCJ25X100-50 FAQ
This 25 mm bore double-acting cylinder has a 1/8" port and a Ø10 mm rod. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, or 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical max of 50 kgf at 1.0 MPa. The 100 mm base stroke can be shortened by up to 50 mm on the extend end.
No, this specific SKU does not include a magnet (-S), so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The variable air cushion and external adjuster handle motion control, but note the cushion only decelerates the piston; it does not lock or hold the load.
