Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-40
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-40 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 MFCJ40X60-40
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 40 mm (usable 20-60 mm), while the needle variable air cushion at both ends soaks up high-speed impact for smooth motion. It features a 1/4" port, a 16 mm rod with an M14x1.5 male thread, and operates at 30-800 mm/s.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, the body is deliberately shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. Delivering 628.3 N push force at 0.5 MPa, it handles a safe working load of roughly 377 N or lifts about 32 kg vertically with a 2:1 margin. Note this specific SKU lacks the -S magnet and cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-40 Is Used
High-Speed Forming Press
Dial in the 20-60 mm extend position on the fly and use the variable air cushion to absorb impact when ejecting 30 kg metal blanks at high speed.
Package Divertor
Shorten the stroke by up to 40 mm during product changeovers, letting the 628.3 N push force smoothly redirect heavy cartons without end-of-stroke slamming.
Pallet Stopper Gate
Adjust the stopper reach on-site for mixed pallet sizes; the needle cushion brings the 16 mm rod to a quiet, controlled stop despite rapid cycling.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-40 the Right Cylinder?
When sizing this series, compare the real thrust: this 40 mm bore pushes 628.3 N at 0.5 MPa, whereas the smaller MFCJ32 provides 402.2 N. Choose the 40 mm bore when moving heavier fixtures, and rely on the 40 mm adjustable window to dial in the exact extend position during high-speed changeovers or shock-sensitive trial fits.
Mounting options include LB foot, FA flange, and TC trunnion (there is no SDB or back-cover option). Because this is a non-magnet SKU, sensing is not possible; add the -S option for CMSG/DMSG/EMSG switches. The air cushion only decelerates the piston near the end of stroke—it is not a lock or brake. If the application must hold a load on air loss, install an external rod lock or pilot check valve to prevent drift.
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 MFCJ40X60-40 FAQ
This 40 mm bore cylinder has a 1/4" port and a 16 mm rod. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 40 mm (usable range 20-60 mm), and the variable air cushion at both ends decelerates the piston near stroke end for smooth stops. This specific SKU lacks the -S magnet, so it cannot take CMSG, DMSG, or EMSG sensors.
