This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-10-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-10-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).
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-10-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-10-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 215 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-10-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-10-S
The AirTAC MALJ40X225-10-S is a discontinued double-acting, single-rod mini cylinder with a 40mm bore and 225mm stroke. It provides 628N push and 528N pull force at 0.5MPa. The -10 adjuster lets you trim the rear end position by up to 10mm, creating a usable stroke window of 215-225mm. The exact drop-in replacement is the MBLJ40X225-10-S, matching the bore, stroke, force, and G1/4 port.
This SKU includes the -S magnet for position sensing. The original MALJ uses older CS1-M/DS1-M switches and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body and modern CMSG/DMSG/EMSG sensors. The rear adjuster is a travel stop, not a lock, and the cylinder uses a fixed rubber bumper, not an adjustable air cushion.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-10-S Is Used
Packaging Carton Flap Folding
Dials in the exact 215-225mm reach to fold varying corrugated box flaps without repositioning the cylinder bracket, using the 628N push force to cleanly crease heavy cardboard.
Assembly Line Pin Insertion
Provides a precise mechanical stop for pressing dowel pins into aluminum housings, using the 10mm fine-tune window to prevent bottoming out and adjust for different pin lengths.
Woodworking Panel Stops
Acts as an adjustable depth stop on a routing conveyor, allowing operators to trim the 225mm stroke by up to 10mm to accommodate different cabinet panel widths on the fly.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-10-S with MBLJ40X225-10-S
To replace the MALJ40X225-10-S, order the exact drop-in MBLJ40X225-10-S. Confirm the 40mm bore, 225mm stroke, 10mm adjust code, G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The -S magnet requires switching from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. Remember the adjuster sets the end position but will not hold a load without live air.
For sizing flexibility, you can step down to a 32mm bore (offering 402N push at 0.5MPa) or step up to the largest 40mm bore option if you need the maximum 128kgf at 1.0MPa. At 225mm, the 16mm rod is robust, but always minimize side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X225-10-S (same bore/stroke/adjust)
- ✓ Same 215–225 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 MBLJ40X225-10-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-10-S FAQ
Yes, the MALJ40X225-10-S is discontinued. The exact drop-in replacement is the MBLJ40X225-10-S, which matches the 40mm bore, 225mm stroke, 10mm adjuster, and G1/4 port. The MBLJ uses a riveted body instead of threaded covers, and if you use the -S magnet, you must upgrade from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors.
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 -10 adjuster is a rear travel stop that lets you shorten the end position by up to 10mm, giving a usable stroke window of 215-225mm. It is a stop, not a lock, and will not hold a load without live air.
