Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-50S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-50S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 60mm stroke, 1/4" 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 MFCJ40X60-50S
Tune both the extend reach and end-of-stroke shock on-site with this 40 mm bore adjustable-stroke mini cylinder. The external adjuster shortens the extend stroke by up to 50 mm (yielding a 10-60 mm usable window), while the needle-set variable air cushion at both ends soaks up high-speed impact for smooth, quiet motion. A built-in magnet (-S) enables CMSG, DMSG, or EMSG switches for position sensing.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it resists mild corrosion and washdown. It is also shorter than an ISO 6432 cylinder for the same bore and stroke, saving mounting length. Delivering 628.3 N push force at 0.5 MPa, it offers a safe working load of roughly 377 N and lifts about 32 kg vertically with a 2:1 margin. The 1/4" port and M14x1.5 male rod thread handle robust pneumatic flow.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-50S Is Used
High-Speed Component Pressing
Dial in the exact 10-60 mm extend reach for pressing bearings, using the variable air cushion to absorb the 879.6 N peak force at 0.7 MPa without shock loading the frame.
Automated Divert Tuning
Fine-tune the actuation length on the fly during product changeovers, relying on the 628.3 N push force to positively divert heavy packages on a high-speed conveyor line.
Carton Sealing Adjustment
Adjust the extend stroke to match varying carton sizes and use the dual air cushions to prevent end-cap slam during rapid 30-800 mm/s cycling, ensuring consistent flap folding.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-50S the Right Cylinder?
Choose between the two available bores based on your force needs: the MFCJ32 provides 402.2 N push at 0.5 MPa, while this MFCJ40 delivers 628.3 N. Select this 40 mm bore when your changeover requires moving heavier fixtures at high speed and you need to dial in the exact extend position and cushioning on the fly. The -S magnet allows seamless sensor integration for automated feedback.
Remember that the air cushion only decelerates the piston near the stroke end and the adjuster sets the end position; neither acts as a mid-stroke lock or brake. If the load must be held during air loss or valve centring, the piston will drift, so you must add an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover mount).
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 MFCJ40X60-50S FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 50 mm (usable range 10-60 mm), and the needle variable air cushion decelerates the piston at both ends. It does not hold position on air loss; for load holding, install an external rod lock or pilot check valve. The -S magnet supports CMSG, DMSG, and EMSG sensors.
