This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X50-40S, 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).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-40-S
The AirTAC MALJ32 Adjustable Mini Cylinder MALJ32X50-40-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 10 to 50 mm. This model is discontinued — the direct replacement is the MBLJ32X50-40-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-40-S
The AirTAC MALJ32X50-40-S is a discontinued 32mm bore, double-acting double-rod cylinder with a 50mm stroke and a 40mm rear adjustable stopper. This yields a usable 10-50mm end-position window. The direct replacement is the MBLJ32X50-40-S, matching the force, G1/8 port, and FA/LB mounting.
The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. This MALJ has threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. The -S magnet works with CS1-M/DS1-M switches, whereas the MBLJ uses CMSG/DMSG/EMSG sensors.

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 MBLJ32X50-40-S carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 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 MBLJ32X50-40-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-40-S Is Used
Tube End Facing Lathe
Fine-tune the rear stopper to control the facing travel of a copper tube end-facing lathe, preventing the 12mm rod from over-traveling and crashing the cutter.
Pneumatic Press Pin Insert
Regulate the downstroke on a small pneumatic press for inserting dowel pins, using the 346N pull force to positively retract the tool after the pin seats.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-40-S with MBLJ32X50-40-S
To replace this MALJ32X50-40-S, order the exact direct replacement MBLJ32X50-40-S. Confirm the 32mm bore, 50mm stroke, 40mm adjust code, G1/8 port, PT threads, and FA/LB mounting (no back cover or SDB). The -S magnet requires switching from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X50-40-S (same bore/stroke/adjust)
- ✓ Same 10–50 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 MBLJ32X50-40-S instead of this discontinued model.
