This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X400-30, 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).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 370 to 400 mm. This model is discontinued — the direct replacement is the MBLJ32X400-30.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30
The AirTAC MALJ32X400-30 is a discontinued adjustable-stroke mini cylinder. As a direct replacement, use the MBLJ32X400-30, which matches the 32mm bore, 400mm stroke, G1/8 port and force ratings. This double-acting double-rod unit has a rear screw stopper that lets you trim up to 30mm, creating a usable end-position window of 370-400mm without external stops.
This SKU lacks a magnet (-S), so it cannot take a position sensor. The rear adjuster sets the travel stop but does not hold load without live air. It uses a fixed rubber bumper, not an adjustable cushion. The original MALJ uses threaded covers and a carbon-steel rod with a 20um hard chrome layer, while the MBLJ upgrade features a riveted rolling-packed body. Because this is a 400mm stroke, minimize side loads to prevent rod bending.

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X400-30 |
| Bore size | Ø32 mm |
| Stroke | 400 mm |
| Adjustable window | 370 – 400 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| 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 MBLJ32X400-30 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 MBLJ32X400-30 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30 Is Used
Long-Reach Carton Flap Folder
Adjust the end position on a packaging line folder to perfectly square tall carton flaps at 400mm without adding bulky external stopper blocks.
Textile Fabric Press
Fine-tune the pressing reach on a fabric calendering machine, relying on the fixed rubber bumper to soften the impact at the end of the 400mm travel.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30 with MBLJ32X400-30
To replace the MALJ32X400-30, order the exact direct replacement MBLJ32X400-30. Confirm the 32mm bore, 400mm stroke, 30mm adjust code, G1/8 PT port, M10x1.25 rod-end thread, and FA or LB mounting (no back cover or SDB). Since this SKU has no -S magnet, you cannot install a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if needed. Remember the adjuster is a travel stop, not a lock.
At 400mm stroke, ensure your guide bearings handle side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ32X400-30 (same bore/stroke/adjust)
- ✓ Same 370–400 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 MBLJ32X400-30 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30 FAQ
Yes, the MALJ32X400-30 is discontinued. The direct replacement is the MBLJ32X400-30, which matches the 32mm bore, 400mm stroke, 30mm adjuster, G1/8 port and force. The MBLJ upgrades the body to a riveted rolling-packed design but retains the same ratings.
The 30mm adjuster is a travel stop that lets you shorten the usable stroke window to 370-400mm; it does not hold the load without live air.
