This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X400-20S, 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 MALJ32X400-20-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-20-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 380 to 400 mm. This model is discontinued — the direct replacement is the MBLJ32X400-20-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-20-S
The AirTAC MALJ32X400-20-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. The direct replacement is the MBLJ32X400-20-S, matching the 32mm bore, 400mm stroke, G1/8 port and 20mm adjuster.
The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. The fixed rubber bumper softens end impact but offers no adjustable cushioning. Upgrading to the MBLJ brings a riveted rolling-packed body instead of threaded covers, and the -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. At 400mm, the 12mm rod is highly susceptible to side-load bending.

| Bore size | Ø32 mm |
| Stroke | 400 mm |
| Adjustable window | 380 – 400 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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 MBLJ32X400-20-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 MBLJ32X400-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-20-S Is Used
PCB Conveyor Diverter
Dial in the 380-400mm reach on a conveyor diverter to clear wide PCB panels without adding external physical stops to the machine frame.
Textile Loom Tensioner
Trims the 400mm full extension by up to 20mm to set exact fabric take-up limits on a weaving loom, ensuring the fixed rubber bumper absorbs the rapid end impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-20-S with MBLJ32X400-20-S
To replace this MALJ32X400-20-S, order the MBLJ32X400-20-S direct. Confirm the 32mm bore, 400mm stroke, 20mm adjust code, G1/8 PT port, M10x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The -S magnet requires CMSG/DMSG/EMSG sensors for the new body. Remember the adjuster is a stop, not a lock. For any 400mm stroke, use guide rails to prevent rod-bending side loads.
Upgrade checklist
- ✓ Order the MBLJ32X400-20-S (same bore/stroke/adjust)
- ✓ Same 380–400 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 MBLJ32X400-20-S instead of this discontinued model.
