This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X400-40, 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 MALJ32X400-40
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-40 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 360 to 400 mm. This model is discontinued — the direct replacement is the MBLJ32X400-40.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-40
The AirTAC MALJ32X400-40 is a discontinued double-acting, double-rod mini cylinder with a 32 mm bore and 400 mm stroke. A rear stopper lets you trim up to 40 mm, creating a usable 360-400 mm end-position window. The direct replacement is the MBLJ32X400-40, matching the bore, stroke, adjust code, G1/8 port, and mounting.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Upgrading to the MBLJ brings a riveted rolling-packed body instead of threaded covers, and if you later need a sensor, the MBLJ uses modern CMSG/DMSG/EMSG switches rather than the older CS1-M/DS1-M.

| 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 MBLJ32X400-40 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 MBLJ32X400-40 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-40 Is Used
PCB Router Z-Axis Depth Stop
Dialing the 40 mm adjuster on this 400 mm stroke cylinder sets the plunge depth for a PCB depaneling router, compensating for bit wear without reprogramming the PLC.
Carton Flap Folder Tensioning
Adjusting the end position by up to 40 mm regulates the folding arm reach on a packaging line carton sealer, ensuring consistent flap creases across varied box widths.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-40 with MBLJ32X400-40
To replace this MALJ32X400-40 with the MBLJ32X400-40, confirm the 32 mm bore, 400 mm stroke, 40 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB allowed). At 400 mm stroke, the Ø12 mm rod is highly susceptible to side-load bending—ensure rigid guidance to prevent binding. The rear adjuster is a stop, not a lock; use an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ32X400-40 (same bore/stroke/adjust)
- ✓ Same 360–400 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 MBLJ32X400-40 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-40 FAQ
Yes, the MALJ32X400-40 is discontinued. The direct replacement is the MBLJ32X400-40, which matches the 32 mm bore, 400 mm stroke, 40 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The usable adjustment window is 360-400 mm (400 mm stroke minus the 40 mm adjust code). The fixed rubber bumper softens the end impact, but the adjuster is only a travel stop, not a lock.
