This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-75-S in place of this model. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-75-S
The AirTAC MALJ40X225-75-S is a discontinued double-acting, single-rod mini cylinder with a 75mm rear adjuster. This yields a usable stroke window of 150-225mm, letting you dial in the end position without adding external stops. The 40mm bore delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X225-75-S, matching the bore, stroke, G1/4 port, and mounting.
This SKU includes the -S magnet for position sensing. The MALJ uses older CS1-M or DS1-M switches, while the MBLJ replacement upgrades to CMSG, DMSG, or EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper; the MBLJ uses a riveted rolling-packed body. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-75-S Is Used
Injection Mold Ejection
Dial the 150-225mm window to time plastic part ejection precisely, using the 628N push force to strike the stripper plate without overtravel.
Packaging Flap Folding
Adjust the rear stop to set carton flap tuck depth on the fly, accommodating varied box sizes on a single conveyor line without swapping hardware.
Wood Panel Stops
Use the 880N push at 0.7MPa to halt moving plywood sheets at a sander feed table, fine-tuning the off-feed position by up to 75mm.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-75-S with MBLJ40X225-75-S
To replace the MALJ40X225-75-S, order the MBLJ40X225-75-S. Confirm the 40mm bore, 225mm stroke, 75mm adjust code, PT G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). If sizing down, the 32mm bore gives 402N push at 0.5MPa; if sizing up, the 40mm is the largest MALJ bore available. For the 225mm stroke, prevent rod bending by ensuring correct guide alignment to avoid side-load wear. The -S magnet requires CMSG/DMSG/EMSG switches on the new MBLJ body.
Upgrade checklist
- ✓ Order the MBLJ40X225-75-S (same bore/stroke/adjust)
- ✓ Same 150–225 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ40X225-75-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-75-S FAQ
Yes, the MALJ40X225-75-S is discontinued. The exact drop-in replacement is the MBLJ40X225-75-S, which matches the 40mm bore, 225mm stroke, 75mm adjust code, G1/4 port, and FA/LB mounting. You will need to upgrade your sensors from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG switches.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The 75mm adjuster creates a usable stroke window of 150-225mm. The adjuster is a travel stop that sets the end position but does not lock or hold the load without live air.
