This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-100 in place of this model. 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 drop-in replacement is the MBLJ40X150-100.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100
The AirTAC MALJ40X150-100 is a discontinued double-acting single-rod mini cylinder with a 100 mm rear adjustable stroke stopper. It provides a usable end-position window of 50-150 mm. The bore 40 mm body delivers 628 N push and 528 N pull at 0.5 MPa, using a G1/4 port and an M12x1.25 rod-end thread. The fixed rubber bumper absorbs end impacts, but the adjuster is a travel stop, not a lock.
The exact drop-in 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 | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X150-100 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100 Is Used
Palletizer End Effectors
Dial in the 50-150 mm reach on a palletizer arm to seat cartons precisely without re-mounting hardware, using the 880 N push at 0.7 MPa to secure heavy loads.
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 drop-in 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.
If you are sizing this cylinder, you can step down to the 32 mm bore (402 N push @0.5 MPa) for lighter duties, or step up if you need more force. 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.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100 FAQ
Yes, the MALJ40X150-100 is discontinued. The exact drop-in replacement is the MBLJ40X150-100, which matches the 40 mm bore, 150 mm stroke, 100 mm adjust code, G1/4 port, and 628 N push force. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG / DMSG / EMSG sensors.
The bore 40 mm cylinder provides 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum 128 kgf at 1.0 MPa. The 100 mm adjust code allows you to trim the rear stopper, creating a usable stroke window of 50-150 mm. The adjuster is a travel stop, not a lock, and cannot hold a load without live air.
