Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-40
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-40 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MFCJ40X160-40
Dial in exact end positions and absorb high-speed shocks with the AirTAC MFCJ40X160-40, a JIS-standard round-body mini cylinder. This double-acting actuator features a 40 mm external adjuster that shortens the extend stroke on-site (usable range 120-160 mm) alongside a variable air cushion at both ends. The SUS304 stainless barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 cylinder while resisting mild washdown corrosion.
Operating at 0.15-1.0 MPa through 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 roughly 377 N, or lifting about 32 kg vertically with a 2:1 margin. Note this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-40 Is Used
Press Fit Tuning
Micro-adjust the 120-160 mm extend stroke on a press fixture to accommodate part tolerances, relying on the 628.3 N push force to seat components smoothly.
High-Speed Diverting
Divert heavy packages on a conveyor at 800 mm/s while the needle air cushion soaks up end-of-stroke shock, preventing rebound during rapid changeovers.
Carton Sealing Jaws
Fine-tune the crushing depth on sealing jaws using the 40 mm adjuster, safely lifting about 32 kg of vertical carton weight with a 2:1 margin.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-40 the Right Cylinder?
Choose the MFCJ40 over the smaller MFCJ32 when your application demands serious thrust: the 40 mm bore pushes 628.3 N at 0.5 MPa compared to 402.2 N for the 32 mm variant. The 40 mm adjustable window is ideal for high-speed changeovers where both the exact extend endpoint and end-of-stroke shock need field tuning. Foot (LB), flange (FA), and trunnion (TC) mounts are available, but there is no SDB or back-cover option.
Remember that the variable air cushion only decelerates the piston near the stroke end; it is not a brake. If the load must hold position during air loss or valve centering, the piston will drift. For suspended loads, install an external rod lock or pilot-operated 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 MFCJ40X160-40 FAQ
This 40 mm bore cylinder features 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 maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must order the -S variant for sensing capabilities. The 40 mm external adjuster shortens the extend stroke, and the variable air cushion decelerates the piston but does not lock the load.
