This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X100-40, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALJ40X100-40

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40
The AirTAC MALJ40X100-40 is a discontinued double-acting double-rod cylinder with a 40mm bore and 100mm stroke. It is discontinued and the direct replacement is the MBLJ40X100-40. The -40 adjust code lets you trim up to 40mm at the rear screw, creating a usable 60-100mm end-position window.
This SKU has no -S magnet, so it cannot take 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. Upgrading to the MBLJ40X100-40 changes the sensor family (if added) from CS1-M/DS1-M to CMSG/DMSG/EMSG, and swaps the threaded covers for a riveted rolling-packed body. Impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.

The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ40X100-40 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ40X100-40 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40 Is Used
Carton Flap Folding
Set a precise 80mm end stroke on packaging lines to tuck heavy cardboard flaps, relying on the fixed rubber bumper to absorb the 880N impact at 0.7MPa.
Pneumatic Rivet Squeezing
Adjust the jaw closure depth for varying aluminum rivet lengths in aircraft panel assembly, ensuring consistent pressure without bottoming out the rod.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-40 with MBLJ40X100-40
To replace this MALJ40X100-40 with the MBLJ40X100-40, confirm the 40mm bore, 100mm stroke, -40 adjust code, G1/4 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a sensor. The adjuster is a stop, not a lock; add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ40X100-40 (same bore/stroke/adjust)
- ✓ Same 60–100 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 MBLJ40X100-40 instead of this discontinued model.
