This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X40-40S, 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 MALJ32X40-40S
The AirTAC MALJ32X40-40S is a discontinued double-acting, double-rod mini cylinder with a 32 mm bore and a 40 mm adjustable stroke. Its rear stopper lets you dial the usable end position down to a 0-40 mm window. The direct replacement is the MBLJ32X40-40S, matching the bore, stroke, G1/8 port, and mounting.
This SKU includes the -S magnet, which uses the older CS1-M / DS1-M switches; the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ features a riveted rolling-packed body. Remember, the rear adjuster is a travel stop that sets the end position; it does not hold the load without live air pressure.

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 MBLJ32X40-40S carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 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 MBLJ32X40-40S matches these values.

Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40S with MBLJ32X40-40S
To replace this MALJ32X40-40S, order the MBLJ32X40-40S. Confirm the 32 mm bore, 40 mm stroke, 40 mm adjust code, PT G1/8 port, and FA or LB mounting (no back cover or SDB). The -S magnet sensor family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG. The adjuster is a travel stop, not a lock; use an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ32X40-40S (same bore/stroke/adjust)
- ✓ Same 0–40 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 MBLJ32X40-40S instead of this discontinued model.
