This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X500-20, 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 MALJ32X500-20
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-20 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 480 to 500 mm. This model is discontinued — the direct replacement is the MBLJ32X500-20.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-20
The AirTAC MALJ32X500-20 is a discontinued double-acting, adjustable-stroke mini cylinder. It features a 32mm bore, 500mm stroke, and a 20mm rear adjuster, giving a usable extension window of 480-500mm. The direct replacement is the MBLJ32X500-20, matching the bore, stroke, and force.
This SKU lacks a magnet (-S), so it cannot take a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. It uses a fixed rubber bumper, not an adjustable air cushion. Upgrading to the MBLJ changes the threaded covers to a riveted rolling-packed body.

| Bore size | Ø32 mm |
| Stroke | 500 mm |
| Adjustable window | 480 – 500 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 MBLJ32X500-20 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 MBLJ32X500-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-20 Is Used
Palletizer Stopper Gate
Trims the end position by 20mm to align a pallet stop gate precisely, relying on the fixed rubber bumper to absorb the impact of incoming 402N loads.
Long-Stroke Conveyor Diverter
Adjusts the retract depth on a 500mm lane diverter to tune the gap for varying carton widths without adding external physical stops.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-20 with MBLJ32X500-20
To replace this MALJ32X500-20, order the MBLJ32X500-20. Confirm the 32mm bore, 500mm stroke, 20mm adjust code, G1/8 port, PT thread, and Basic mounting (no back cover or SDB allowed). Since this SKU lacks a -S magnet, it cannot accept a sensor; if you need sensing on the new unit, specify an MBLJ-S and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster is a stop, not a lock.
At 500mm stroke, the 12mm rod is highly susceptible to side-load buckling; ensure rigid guidance to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ32X500-20 (same bore/stroke/adjust)
- ✓ Same 480–500 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 MBLJ32X500-20 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-20 FAQ
Yes, the MALJ32X500-20 is discontinued. The direct replacement is the MBLJ32X500-20, which matches the 32mm bore, 500mm stroke, 20mm adjuster, and force. The MBLJ upgrades the construction with a riveted rolling-packed body instead of threaded covers.
The 20mm rear adjuster is a travel stop only, not a lock; it cannot hold a load without live air pressure. This SKU also lacks a magnet, so it cannot accept a position sensor.
