This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X130-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X130-20 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 MALJ40X130-20
The AirTAC MALJ40X130-20 is a discontinued double-acting, single-rod mini cylinder with a 40mm bore and a 130mm stroke. It features a rear adjustable stroke stopper that lets you trim up to 20mm, providing a usable end-position window of 110-130mm. Delivering 628N push and 528N pull at 0.5MPa, it uses a G1/4 port and a Ø16mm carbon-steel rod with hard chrome plating. This SKU has no magnet, meaning it cannot accept a position sensor.
The exact drop-in replacement is the MBLJ40X130-20, matching the bore, stroke, force, and port. The MALJ uses threaded covers and fixed rubber bumpers, while the MBLJ upgrades to a riveted rolling-packed body. Remember, the rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X130-20 Is Used
Printed Circuit Board Drill Press
Dial the 110-130mm window to set precise Z-axis drilling depth on multi-layer PCBs, using the 628N push force to drive the spindle without bottoming out.
Aluminum Extrusion Cutoff Saw
Acts as a travel stop for the saw actuator, trimming the 20mm range to perfectly flush-cut aluminum profiles while relying on the fixed rubber bumper to absorb shock.
Carton Flap Folder
Adjusts the rear stroke position on the fly to match varying box heights, using the 528N pull force to bring the folding arms back without needing new hardware.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X130-20 with MBLJ40X130-20
To replace the MALJ40X130-20, order the drop-in MBLJ40X130-20. Confirm the 40mm bore, 130mm stroke, 20mm adjust code, G1/4 port, and PT thread. Mounting is FA or LB only; there is no back-cover or SDB option. Since this SKU lacks a -S magnet, it cannot take a sensor, unlike the CMSG/DMSG/EMSG compatible MBLJ. The adjuster is a travel stop, not a lock, so add an external lock for held loads.
For sizing, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to the 50mm bore (from the standard MAL series) gives 981N push. The 40mm bore provides 628N push and 528N pull, making it ideal for medium-force tasks. At 130mm stroke, keep rod-to-side-load alignment tight to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X130-20 (same bore/stroke/adjust)
- ✓ Same 110–130 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 MBLJ40X130-20 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X130-20 FAQ
Yes, the MALJ40X130-20 is discontinued. The exact drop-in replacement is the MBLJ40X130-20, matching the 40mm bore, 130mm stroke, 20mm adjust code, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design; if you need a sensor, the MBLJ uses CMSG/DMSG/EMSG switches, while this no-S MALJ cannot take one.
The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a max of 128kgf at 1.0MPa. The 20mm adjuster lets you trim the rear end position, creating a usable stroke window of 110-130mm. The adjuster is a travel stop, not a lock; it sets the end position but does not hold the load without live air.
