This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-40, 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 MALJ32X450-40
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40 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 410 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-40.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40
The AirTAC MALJ32X450-40 is a discontinued adjustable-stroke mini cylinder. The direct replacement is the MBLJ32X450-40, matching the 32 mm bore, 450 mm stroke, G1/8 port, and 40 mm adjuster. This SKU lacks a magnet, so it cannot take a position sensor.
The rear screw gives a usable travel window of 410-450 mm without external stops. The adjuster is a travel stop, not a lock; it will not hold a load without live air. This MALJ has threaded covers and a fixed rubber bumper, whereas the MBLJ upgrade uses a riveted rolling-packed body. At 450 mm, the 12 mm rod is vulnerable to side-load bending.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40 Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X450-40 |
| Bore size | Ø32 mm |
| Stroke | 450 mm |
| Adjustable window | 410 – 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 MBLJ32X450-40 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 MBLJ32X450-40 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40 Is Used
PCB Router Z-Axis
Dials the 410-450 mm plunge depth on a routing spindle.
Door Panel Edge Bender
Sets the final reach for applying edge banding. The 346 N pull force retracts the applicator safely, and the 40 mm window allows tooling changes without swapping the cylinder.
Carton Flap Folder
Adjusts the stroke window to fold varying box heights. The fixed rubber bumper absorbs the end impact, while the stop lets operators tune the fold position on the fly.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40 with MBLJ32X450-40
To replace this MALJ32X450-40, install the MBLJ32X450-40. Confirm the 32 mm bore, 450 mm stroke, 40 mm adjust code, G1/8 PT port, and M10x1.25 rod thread. Mounting is Basic, FA, or LB only (no back cover or SDB). Because this SKU has no -S magnet, you lose position sensing; the MBLJ -S upgrade uses CMSG/DMSG/EMSG switches. Remember the rear adjuster is a stop, not a lock.
At 450 mm, ensure front mounting to prevent rod bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ32X450-40 (same bore/stroke/adjust)
- ✓ Same 410–450 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 MBLJ32X450-40 instead of this discontinued model.
