This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X225-50, 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 MALJ32X225-50
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-50 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 175 to 225 mm. This model is discontinued — the direct replacement is the MBLJ32X225-50.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-50
The AirTAC MALJ32X225-50 is a discontinued 32mm bore, double-acting double-rod mini cylinder with a 50mm rear adjustable stroke stopper. It provides a usable extension window of 175-225mm.
This SKU lacks a magnet (-S), so it cannot accept 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. The original MALJ uses threaded covers and fixed rubber bumpers, while the MBLJ upgrade features a riveted rolling-packed body.

| Bore size | Ø32 mm |
| Stroke | 225 mm |
| Adjustable window | 175 – 225 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 MBLJ32X225-50 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 MBLJ32X225-50 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-50 Is Used
Carton Flap Folder
Adjust the rear stopper on a packaging line to fold varying corrugated carton heights, relying on the fixed rubber bumper to absorb the end-of-stroke impact.
Pneumatic Rivet Squeezer
Fine-tune the squeeze gap for different rivet lengths in an aerospace assembly jig, setting the exact 32mm bore reach without adding external shims.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-50 with MBLJ32X225-50
Replace this MALJ32X225-50 directly with the MBLJ32X225-50, confirming the 32mm bore, 225mm stroke, 50mm adjust code, PT G1/8 port, and FA/LB mounting (no back cover or SDB allowed). Because this SKU lacks the -S magnet, it cannot hold a sensor; upgrading to an -S MBLJ moves you from the legacy CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG family.
The 50mm adjuster screw lets you dial in depth without external stops, but remember it acts only as a travel stop, not a mechanical lock.
Upgrade checklist
- ✓ Order the MBLJ32X225-50 (same bore/stroke/adjust)
- ✓ Same 175–225 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 MBLJ32X225-50 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X225-50 FAQ
Yes, the MALJ32X225-50 is discontinued. The direct replacement is the MBLJ32X225-50, which matches the 32mm bore, 225mm stroke, 50mm adjuster, G1/8 port, and 82kgf max force. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The 50mm adjust code allows you to trim the rear stopper, creating a usable stroke window of 175-225mm. This adjuster is a travel stop only, not a lock, and this no-magnet SKU cannot accept a sensor.
