Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-20
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-20 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 MFCJ40X160-20
Tune both travel and end-of-stroke shock precisely with the AirTAC MFCJ40X160-20, a JIS-standard round-body mini cylinder. It features a SUS304 stainless steel barrel and riveted aluminium covers, offering a shorter mounting length than a comparable ISO 6432 unit while resisting mild washdown. The external adjuster shortens the extend stroke by up to 20 mm on-site (usable range 140-160 mm), and needle valves set a variable air cushion at both ends to absorb high-speed impact.
This double-acting 40 mm bore cylinder delivers 628.3 N of push force at 0.5 MPa through its 1/4" port, peaking at a theoretical 128.1 kgf. It yields a safe working load of about 377 N, lifting roughly 32 kg vertically with a 2:1 margin. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-20 Is Used
High-Speed Diverters
Dial in the 140-160 mm extend stroke and tune the needle cushion to softly stop 32 kg loads shifting at 800 mm/s without slam-bang impacts.
Press Fit Tuning
Leverage the 628.3 N push force to seat components, using the 20 mm adjuster to perfect the crush depth during sensitive tooling changeovers.
Packaging Stroke Setup
Shorten the extend end on the fly for various carton sizes, relying on the variable air cushion to silently absorb the end-of-stroke shock.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-20 the Right Cylinder?
Choose the MFCJ40 over the MFCJ32 when you need serious thrust, stepping up from 402.2 N to 628.3 N at 0.5 MPa. The adjustable 20 mm extend window paired with the variable air cushion is perfect for high-speed changeovers or shock-sensitive trial fits where the exact end position and deceleration must be dialed in on the machine. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable). Remember that the cushion only decelerates the piston; it does not lock or hold the load. If you need vertical position holding on air loss, add an external rod lock or pilot check valve. Because this code has no -S magnet, position sensing is unsupported.
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 MFCJ40X160-20 FAQ
This 40 mm bore double-acting cylinder uses a 1/4" port and a 16 mm rod with an M14x1.5 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 the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select an -S variant for magnetic sensing. The external adjuster only shortens the extend stroke by up to 20 mm; it is not a mid-stroke lock.
