Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-100S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-100S 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 MFCJ40X160-100S
Dial in exact extend positions and absorb high-speed shocks with the AirTAC MFCJ40X160-100S. This double-acting JIS-standard round-body mini cylinder features a 100mm adjustable stroke window and a needle-set variable air cushion at both ends. Built with a SUS304 stainless barrel and riveted aluminium covers, it resists mild corrosion and washdowns while saving mounting length compared to an ISO 6432 unit.
Delivering 628.3N push and 527.8N pull force at 0.5MPa, this 40mm bore model handles robust loads. The integrated magnet (-S) supports CMSG, DMSG, and EMSG sensors for position feedback. It operates at 30-800mm/s, uses a 1/4" port, and offers a safe working load of about 377N or a 32kg vertical lift with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-100S Is Used
High-Speed Diverting
Tune the 100mm extend window and set the needle air cushion to smoothly halt the 628.3N push force when routing heavy packages on a conveyor line.
Adjustable Press Fits
Perfect for trial-and-error press operations where the exact insertion depth varies, letting you shorten the extend stroke on-site without swapping cylinders.
Pallet Stop Arms
Absorb the shock of moving pallets using the variable air cushion while adjusting the stop arm reach within the 100mm window to handle different load sizes.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X160-100S the Right Cylinder?
Choose the MFCJ40 over the MFCJ32 when you need extra muscle: the 40mm bore pushes 628.3N at 0.5MPa, whereas the 32mm bore delivers 402.2N. The external adjuster shortens the extend stroke by up to 100mm on-site, perfect for trial fits and high-speed changeovers where end-of-stroke shock also requires tuning via the variable air cushion.
Mount this cylinder using LB foot, FA flange, or TC trunnion brackets (SDB and back-cover mounts are unavailable). Note that the air cushion only decelerates the piston near stroke end; it does not lock or hold the load. If you need to prevent drift on air loss, install an external rod lock or pilot check valve. The -S magnet enables CMSG, DMSG, or EMSG switches for precise end-position sensing.
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 MFCJ40X160-100S FAQ
This 40mm bore cylinder features a 1/4" port and a 16mm rod. It generates 628.3N push and 527.8N pull at 0.5MPa, 879.6N push and 738.9N pull at 0.7MPa, with a theoretical max of 128.1kgf at 1.0MPa.
The external adjuster shortens the extend stroke by up to 100mm on-site for fine-tuning end positions. The variable air cushion at both ends decelerates the piston to reduce shock at high speeds. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
