This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X110-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X110-20 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 MALJ40X110-20
The AirTAC MALJ40X110-20 is a discontinued double-acting single-rod cylinder with a 40mm bore and 110mm stroke. The rear screw stopper lets you trim up to 20mm, giving an exact usable end-position window of 90-110mm. It delivers 628N push and 528N pull at 0.5MPa. The direct drop-in replacement is the MBLJ40X110-20, matching the bore, stroke, G1/4 port, and mounting.
This SKU has no -S magnet and cannot take a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but holds no load without live air. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X110-20 Is Used
Press Fit Stop
Dial in the 90-110mm reach on a bearing press to seat caps without bottoming out, using the 628N push force at 0.5MPa to set the exact depth.
Forming Pin Locator
Adjust the end position on a sheet metal forming line to locate pins precisely, relying on the 16mm rod to resist deflection during the hit.
Packaging Depth Stop
Tune the rear 20mm adjuster on a carton flap folder to handle varying box heights without swapping hardware, using the fixed rubber bumper to soften impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X110-20 with MBLJ40X110-20
To replace the MALJ40X110-20, order the MBLJ40X110-20. Confirm the 40mm bore, 110mm stroke, 20mm adjust code, G1/4 port, PT thread, and FA or LB mounting (no back cover or SDB allowed). Since this SKU lacks the -S magnet, it cannot accept a sensor; upgrading to an MBLJ-S gets you the modern CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M. Remember the adjuster is a stop, not a lock.
For sizing, step down to the 32mm bore (402N push at 0.5MPa) if your load is lighter, or step up to this 40mm bore (628N push) from the 32mm if you need more force. The 40mm is the largest available MALJ bore.
Upgrade checklist
- ✓ Order the MBLJ40X110-20 (same bore/stroke/adjust)
- ✓ Same 90–110 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 MBLJ40X110-20 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X110-20 FAQ
Yes, the MALJ40X110-20 is discontinued. The exact drop-in replacement is the MBLJ40X110-20, matching the 40mm bore, 110mm stroke, 20mm adjust code, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
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 20mm adjuster is a travel stop that creates a usable stroke window of 90-110mm; it does not hold the load without live air. This SKU has no magnet and cannot take a sensor.
