Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-100
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-100 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 MFCJ40X200-100
Trim the extend stroke by up to 100 mm on site and dial in a needle air cushion at each end to absorb high-speed shock. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting length than a comparable ISO 6432 unit while resisting mild washdown corrosion.
Fitted with a 16 mm rod, M14x1.5 male thread, and a 1/4" port, the 40 mm bore generates 628.3 N of push force at 0.5 MPa. This translates to a safe working load of about 377 N, letting you lift roughly 32 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG or DMSG position switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-100 Is Used
High-Speed Sorting Diverters
Tune the 100 mm extend window to match varying package sizes while the needle air cushion prevents end-of-stroke slamming at fast cycle speeds.
Machine Tool Clamping
Apply up to 879.6 N of push force at 0.7 MPa to secure parts, adjusting the clamp reach on the fly without disassembling the fixture.
Carton Forming Presses
Set the exact forming depth via the external adjuster and rely on the variable cushion to soften impact during rapid pressing motions.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X200-100 the Right Cylinder?
Choose the MFCJ40 over the 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 100 mm adjustable window is ideal for changeovers requiring precise end-position tuning without machining new hard stops. Mount via LB foot, FA flange, or TC trunnion. Remember that the air cushion only decelerates the piston near the end of travel; it is not a brake. If the load must hold position during air loss, install an external rod lock or pilot check valve.
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 MFCJ40X200-100 FAQ
This 40 mm bore cylinder features a 1/4" air port and a 16 mm rod. It delivers 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.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant to enable magnetic position sensing.
