This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X40-30, 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).

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-30
The AirTAC MALJ32X40-30 is a discontinued double-acting mini cylinder with a rear adjustable stroke stopper. It trims up to 30 mm at the rear, yielding a usable 10-40 mm end-position window. The direct replacement is the MBLJ32X40-30, matching the 40 mm stroke, G1/8 port, and force ratings.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The upgrade moves from threaded covers to a riveted rolling-packed body; if you need sensors on the new unit, switch from the old CS1-M/DS1-M to CMSG/DMSG/EMSG switches. The adjuster sets travel limits but does not hold load without live air, and impact is softened only by a fixed rubber bumper.

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 MBLJ32X40-30 carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 MBLJ32X40-30 matches these values.

Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-30 with MBLJ32X40-30
To replace this MALJ32X40-30, specify the MBLJ32X40-30 to match the 32 mm bore, 40 mm stroke, 30 mm adjust code, G1/8 port, and FA/LB mounting (no back cover or SDB). Note that the rear screw is a travel stop, not a lock, so add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ32X40-30 (same bore/stroke/adjust)
- ✓ Same 10–40 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 MBLJ32X40-30 instead of this discontinued model.
