This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-75S, 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 MALJ32X300-75-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-75-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 225 to 300 mm. This model is discontinued — the direct replacement is the MBLJ32X300-75-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-75-S
The AirTAC MALJ32X300-75-S is a discontinued adjustable-stroke mini cylinder. The 75 mm rear adjuster creates a usable stroke window of 225-300 mm. The direct replacement is the MBLJ32X300-75-S, matching the 32 mm bore, G1/8 port, and 82 kgf max force.
This -S magnet model uses legacy CS1-M or DS1-M switches, while the MBLJ upgrade takes CMSG, DMSG, or EMSG sensors. The MALJ features threaded covers, whereas the MBLJ uses a riveted rolling-packed body. The rear adjuster sets the end position but is a travel stop, not a lock; it cannot hold a load without live air. End impact is softened by a fixed rubber bumper, as there is no 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 MBLJ32X300-75-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 MBLJ32X300-75-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-75-S Is Used
Long-Throw Parts Ejector
Tunes the kick distance on a 300 mm stroke to drop stamped metal parts precisely into a chute without relocating hard stops.
Carton Flap Folder
Adjusts the rear reach to fold varying box flap heights, relying on the fixed rubber bumper to soften the end impact without air cushions.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-75-S with MBLJ32X300-75-S
To replace the MALJ32X300-75-S, install the MBLJ32X300-75-S. Confirm the 32 mm bore, 300 mm stroke, 75 mm adjust code, PT G1/8 port, M10x1.25 rod thread, and FA or LB mounting (no back cover or SDB). Note the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a stop, not a lock; add an external lock to hold loads.
At 300 mm stroke, prevent rod bending by ensuring strict axial alignment and avoiding side loads.
Upgrade checklist
- ✓ Order the MBLJ32X300-75-S (same bore/stroke/adjust)
- ✓ Same 225–300 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 MBLJ32X300-75-S instead of this discontinued model.
