This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-75-S, 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 MALJ32X450-75-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-75-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 375 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-75-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-75-S
The AirTAC MALJ32X450-75-S is a discontinued double-acting double-rod cylinder with a rear adjustable-stroke stopper. It gives a usable stroke window of 375-450 mm by trimming up to 75 mm at the rear. The direct replacement is the MBLJ32X450-75-S, matching the 32 mm bore, 450 mm stroke, G1/8 port and force.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. A fixed rubber bumper softens end impact, but this is not an adjustable cushion. This MALJ has threaded covers and a -S magnet for CS1-M / DS1-M switches. The MBLJ32X450-75-S upgrade shifts to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors.

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
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 MBLJ32X450-75-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 MBLJ32X450-75-S matches these values.

| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-75-S Is Used
Long-reach packaging flap folding
Dials the exact 375-450 mm end position to tuck carton flaps on a variable-width packaging line without swapping hardware.
Palletizer depth stop
Uses the 75 mm rear stop to tune the retract depth for different pallet heights, relying on 402 N pull at 0.5 MPa to clear the load.
Textile loom beam alignment
Sets a precise end position to tension long fabric beams, using the fixed rubber bumper to absorb the rapid 800 mm/s rod impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-75-S with MBLJ32X450-75-S
Replace the MALJ32X450-75-S with the exact direct replacement MBLJ32X450-75-S. Confirm the 32 mm bore, 450 mm stroke, 75 mm adjust code, G1/8 port, PT thread and FA or LB mounting (no back cover or SDB). The -S magnet changes sensor family from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG. The adjuster is a travel stop, not a load lock.
At 450 mm stroke, prevent rod bending and seal wear by guiding the load to minimize side-load on the 12 mm rod.
Upgrade checklist
- ✓ Order the MBLJ32X450-75-S (same bore/stroke/adjust)
- ✓ Same 375–450 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 MBLJ32X450-75-S instead of this discontinued model.
