This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X150-100, 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 MALJ40 Adjustable Mini Cylinder MALJ40X150-100
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 50 to 150 mm. This model is discontinued — the direct replacement is the MBLJ40X150-100.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100
The AirTAC MALJ40X150-100 is a discontinued double-acting double-rod mini cylinder with a 100 mm rear adjustable stroke stopper. It provides a usable end-position window of 50-150 mm. The fixed rubber bumper absorbs end impacts, but the adjuster is a travel stop, not a lock.
The direct replacement is the MBLJ40X150-100, matching the bore, stroke, adjust code, and force. The old MALJ uses threaded covers and a carbon-steel rod with a 20 um hard chrome plating to resist wear. This specific SKU lacks the -S magnet, so it cannot take a CS1-M or DS1-M position sensor. The MBLJ upgrade features a riveted rolling-packed body and uses CMSG / DMSG / EMSG switches.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X150-100 |
| Bore size | Ø40 mm |
| Stroke | 150 mm |
| Adjustable window | 50 – 150 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 MBLJ40X150-100 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 MBLJ40X150-100 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100 Is Used
Injection Mold Ejection
Fine-tune the ejection stroke on an injection molding press, trimming up to 100 mm at the rear stopper to protect deep-cavity tooling during part extraction.
Bending Press Depth Stop
Set a repeatable 50-150 mm stroke window on a metal bending press to form accurate brackets, relying on the fixed rubber bumper to soften the mechanical impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100 with MBLJ40X150-100
To replace this MALJ40X150-100, order the direct replacement MBLJ40X150-100. Confirm the 40 mm bore, 150 mm stroke, 100 mm adjust code, G1/4 port, PT threads, and FA or LB mounting (there is no back cover or SDB option). Because this SKU has no -S magnet, it cannot accept a sensor; the MBLJ upgrade switches to the CMSG / DMSG / EMSG family if you add a magnet. Remember the adjuster sets end position but does not hold load without live air.
Since the 150 mm stroke is below the 500 mm max standard, rod-bending is minimal, but you should still avoid side loads.
Upgrade checklist
- ✓ Order the MBLJ40X150-100 (same bore/stroke/adjust)
- ✓ Same 50–150 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 MBLJ40X150-100 instead of this discontinued model.
