This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X160-20, 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 MALJ40X160-20
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 140 to 160 mm. This model is discontinued — the direct replacement is the MBLJ40X160-20.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20
The AirTAC MALJ40X160-20 is a discontinued 40mm bore adjustable-stroke mini cylinder. The -20 code means you can trim up to 20 mm at the rear, giving a usable end-position window of 140-160 mm. The direct replacement is the MBLJ40X160-20, which shares the same bore, stroke, G1/4 port, and 128 kgf maximum force.
This unit has no magnet (-S), 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, whereas the MBLJ upgrade features a riveted rolling-packed body.

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 MBLJ40X160-20 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

| 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 MBLJ40X160-20 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20 Is Used
Aluminum Extrusion Notching
Sets the exact 150 mm reach for a pneumatic notching press, ensuring the 16 mm rod cleanly retracts the tooling before the profile indexes.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20 with MBLJ40X160-20
To replace the MALJ40X160-20, order the exact direct replacement MBLJ40X160-20. Confirm the 40 mm bore, 160 mm stroke, -20 adjust code, G1/4 port, and PT thread. Mounting is FA or LB only (no back cover or SDB). Because this SKU lacks the -S magnet, it cannot hold a sensor; if you need position detection, step up to an MBLJ with an -S code (which uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M). Remember the adjuster is a stop, not a lock.
At 160 mm stroke, keep the rod side-load minimized to prevent bending the 16 mm carbon-steel rod.
Upgrade checklist
- ✓ Order the MBLJ40X160-20 (same bore/stroke/adjust)
- ✓ Same 140–160 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 MBLJ40X160-20 instead of this discontinued model.
