Airtac MFCJ Adjustable Mini Cylinder MFCJ40X15-10
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X15-10 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 15mm 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 MFCJ40X15-10
Dial in exact end positions and absorb high-speed shocks with the AirTAC MFCJ40X15-10, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. An external adjuster shortens the extend stroke by up to 10 mm on-site, while needle air cushions at both ends decelerate the payload smoothly. The body is purposefully shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length.
This 40 mm bore double-acting actuator uses a 1/4" port and a 16 mm rod with an M14x1.5 male thread. It generates 628.3 N of push force at 0.5 MPa, yielding a safe working load of about 377 N or a 32 kg vertical lift with a 2:1 margin. Note this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG reed switches for position sensing.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X15-10 Is Used
Short-Stroke Clamping
Clamps delicate aluminium parts with a 377 N safe working load, using the 10 mm adjuster to tune the exact grip distance without crushing the workpiece.
High-Speed Diverting
Diverts light cartons on a packaging line at speeds up to 800 mm/s, relying on the variable air cushion to prevent end-of-stroke slamming.
Lab Test Positioning
Acts as a compact actuator for lab test rigs, saving space with a body shorter than ISO 6432 while providing a 32 kg vertical lift margin.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X15-10 the Right Cylinder?
Choose the MFCJ40 over the smaller MFCJ32 when you need extra muscle: the 40 mm bore pushes 628.3 N at 0.5 MPa compared to 402.2 N for the 32 mm variant. The 10 mm adjustable window is ideal for trial fits and high-speed changeovers where the exact extend endpoint and end-of-stroke shock both require field tuning. Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover code is available on this build).
Keep in mind the variable air cushion only decelerates the piston near the stroke end; it is not a brake. If the application must hold a load vertically on air loss, add an external rod lock or pilot-operated check valve, as the piston will drift. To add sensors later, select the -S magnet option, as this base SKU cannot accept a switch.
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 MFCJ40X15-10 FAQ
This 40 mm bore cylinder features a 1/4" port and delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 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 10 mm on-site, making it ideal for changeovers. Needle variable air cushions at both ends soak up high-speed shock. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.
