Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-10
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-10 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 MFCJ40X200-10
Tune both the extend end-point and the end-of-stroke shock on site with this 40 mm bore, 200 mm stroke cylinder. The external adjuster shortens the extend stroke by up to 10 mm, while the needle variable air cushion at both ends soaks up high-speed kinetic energy for smooth deceleration.
Built as a JIS-standard round-body mini with a SUS304 stainless barrel and riveted aluminium covers, it packs a punch with 628.3 N push force at 0.5 MPa. This yields a safe working load around 377 N, or roughly 32 kg of vertical lift with a 2:1 margin. The 1/4" port and M14x1.5 male rod thread handle the airflow, and the body is shorter than an ISO 6432 cylinder for the same stroke.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-10 Is Used
High-Speed Machining Clamps
Use the 628.3 N thrust to secure heavy castings, tuning the 10 mm extend window to perfect jaw closure while the air cushion absorbs the rapid 800 mm/s impact.
Package Diverter Arms
Divert heavy cartons on a sorting line. The variable cushion prevents end-cap slamming during fast retraction, and the SUS304 barrel handles mild washdown.
Adjustable Stop Gates
Set precise material flow stops during line changeovers. The external adjuster lets operators tweak the 200 mm extend position by up to 10 mm without disassembling the mount.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-10 the Right Cylinder?
When sizing this series, you choose between the 40 mm and 32 mm bores. This MFCJ40 delivers 628.3 N push at 0.5 MPa, whereas the MFCJ32 provides 402.2 N. Pick the 40 mm bore if your changeover mechanism or trial fixture needs that extra thrust to shift heavier payloads at speed.
The 10 mm adjust window is perfect for dialling in a precise extend position during commissioning. Remember that the cushion only decelerates the piston near the end of stroke; it is not a brake. If the load must hold position on air loss, add an external rod lock or pilot check valve. Also, because this specific SKU lacks the -S magnet, it cannot take CMSG, DMSG or EMSG sensors.
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 MFCJ40X200-10 FAQ
This 40 mm bore cylinder has 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 max of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot host CMSG, DMSG or EMSG switches. You can still adjust the extend stroke by up to 10 mm and tune the variable air cushion, but position sensing requires an external switch.
