This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-30, 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 MALJ32X450-30
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-30 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 420 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-30.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-30
The AirTAC MALJ32X450-30 is a discontinued double-acting adjustable-stroke mini cylinder. The rear screw stopper trims up to 30 mm, yielding a usable end-position window of 420-450 mm. The direct replacement is the MBLJ32X450-30, matching the 32 mm bore, 450 mm stroke, G1/8 port, and mounting footprint.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The adjuster is a travel stop, not a load lock. Two upgrade details: the MALJ uses threaded covers and older CS1-M/DS1-M sensors, while the MBLJ replacement uses a riveted rolling-packed body and CMSG/DMSG/EMSG switches. Impact is softened by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-30 Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-30 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X450-30 |
| Bore size | Ø32 mm |
| Stroke | 450 mm |
| Adjustable window | 420 – 450 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 MBLJ32X450-30 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 MBLJ32X450-30 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-30 Is Used
PCB Router Z-Axis Depth
Dial the 420-450 mm end position on a printed circuit board routing spindle.
Textile Fabric Take-Up
Set a variable roll diameter stop on a fabric winding frame. The 30 mm rear trim lets operators tune material tension without adding external physical stops.
Wood Panel Edge Gluing
Press laminated edge bands with a 346 N pull force at 0.5 MPa. The fixed rubber bumper softens the 450 mm stroke end impact to protect delicate glue joints.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-30 with MBLJ32X450-30
To replace this MALJ32X450-30, order the direct replacement MBLJ32X450-30. Confirm the 32 mm bore, 450 mm stroke, 30 mm adjust code, G1/8 PT port, and FA/LB mounting (no back cover or SDB). Because this SKU has no -S magnet, it cannot hold a sensor; the MBLJ upgrade uses the CMSG/DMSG/EMSG switch family. The adjuster sets end position but does not hold load without live air.
At 450 mm stroke, prevent rod bending by guiding the load to avoid side-loading.
Upgrade checklist
- ✓ Order the MBLJ32X450-30 (same bore/stroke/adjust)
- ✓ Same 420–450 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 MBLJ32X450-30 instead of this discontinued model.
