Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-10S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-10S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 200mm 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 MFCJ40X200-10S
Trimming the extend end by up to 10 mm on site, this double-acting JIS-standard round-body mini cylinder lets you dial in the exact 190 to 200 mm stroke while a variable air cushion soaks up high-speed end-of-travel shock. The SUS304 stainless barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke, resisting mild washdown. A built-in magnet (-S) enables CMSG, DMSG or EMSG position sensing.
Operating at 0.15 to 1.0 MPa through a 1/4" port, the 40 mm bore generates 628.3 N of push force at 0.5 MPa, making it suitable for safely moving a 377 N working load or vertically lifting about 32 kg with a 2:1 margin. The needle cushion at both ends decelerates the 16 mm rod smoothly across the 30 to 800 mm/s speed range. Note that the cushion only decelerates; use an external rod lock or pilot check valve if you need to hold a load on air loss.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-10S Is Used
High-Speed Machining Clamps
Dial in the 10 mm stroke window to secure heavy steel fixtures, using the variable air cushion to prevent harsh impacts during rapid 628.3 N clamping at 0.5 MPa.
Package Diverters
Fine-tune the actuator endpoint on the fly for varying carton sizes while the needle cushion absorbs shock from fast 30 to 800 mm/s diverting strokes.
Vertical Lift Gates
Lift loads up to 32 kg safely with a 2:1 margin, relying on the -S magnet and DMSG sensors to confirm gate position while planning an external check valve for holding.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-10S the Right Cylinder?
Choose this MFCJ40 model over the smaller MFCJ32 when you need more muscle: the 40 mm bore delivers 628.3 N push at 0.5 MPa compared to 402.2 N for the 32 mm version. The external adjuster is perfect for high-speed changeovers or trial fits where the exact extend endpoint and end-of-stroke shock both need on-the-fly tuning, while the -S magnet supports electronic or reed sensors for confirmation.
Mounting options include LB foot, FA flange and TC trunnion (no SDB or back-cover option). Because the air cushion and adjuster only decelerate and set position rather than locking the piston, any suspended load requires an external rod lock or pilot-operated 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 MFCJ40X200-10S FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm rod with an M14x1.5 male 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 of 128.1 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 10 mm on site (usable extend 190-200 mm), while the variable air cushion at both ends decelerates the piston near the end of travel. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
