This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-75 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 MALJ40X225-75
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 150 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-75.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-75
The AirTAC MALJ40X225-75 is a discontinued 40mm bore, double-acting single-rod mini cylinder with a 225mm stroke and a 75mm rear travel stop. This gives a usable extension window of 150-225mm. It delivers 628N push and 528N pull at 0.5 MPa. The direct drop-in replacement is the MBLJ40X225-75, which matches the bore, stroke, adjuster, G1/4 port and mounting.
This SKU lacks the -S magnet option, so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. The adjuster simply dials back the stroke without external stops.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-75 Is Used
Pallet Dispenser Indexing
Dials the exact 150-225mm push-off stroke to strip empty pallets from a magazine stack without adding external physical stops.
Wood Panel Edge Bumping
Provides 628N of push force to square up cabinet panels on an assembly conveyor, using the 75mm trim to fine-tune the alignment jaw.
Carton Flap Folding
Adjusts the end position to perfectly fold varying box flaps on a packaging line, relying on the fixed rubber bumper to soften impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-75 with MBLJ40X225-75
To replace the MALJ40X225-75, order the MBLJ40X225-75. Confirm the 40mm bore, 225mm stroke, 75mm adjust code, G1/4 PT port, M12x1.25 rod thread and FA/LB mounting. This non-magnet SKU cannot take a sensor; if you need sensing, the MBLJ -S version uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Remember the adjuster is a stop, not a lock.
For sizing flexibility, the next size down is the 32mm bore (402N push at 0.5 MPa), and the next size up is not available in this MALJ family as 40mm is the largest. With a 225mm stroke, minimize side-load to prevent rod-bending and premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X225-75 (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 instead of this discontinued model.
