This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X100-100, 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 MALJ40X100-100
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100 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 0 to 100 mm. This model is discontinued — the direct replacement is the MBLJ40X100-100.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100
The AirTAC MALJ40X100-100 is a discontinued 40mm bore, double-acting adjustable-stroke mini cylinder. The -100 adjuster code lets you trim up to 100mm at the rear, yielding a usable stroke window of 0-100mm.
The direct replacement is the MBLJ40X100-100, matching the bore, stroke, force, G1/4 port, and mounting. Two upgrade facts: the MALJ uses threaded covers while the MBLJ uses a riveted rolling-packed body, and because this specific SKU lacks a -S magnet, it cannot accept any position sensor (unlike the newer CMSG/DMSG/EMSG switches on MBLJ-S models). The rear adjuster sets the end position but is a travel stop, not a lock; it will not hold a load without live air pressure.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X100-100 |
| Bore size | Ø40 mm |
| Stroke | 100 mm |
| Adjustable window | 0 – 100 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 MBLJ40X100-100 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 MBLJ40X100-100 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100 Is Used
PCB Router Z-Axis Depth
Dial the 0-100mm window to set exact plunge depth on a PCB depaneling router.
Carton Flap Folding Arm
Adjust the end position to perfectly fold varying corrugated carton heights on a packaging line. The fixed rubber bumper absorbs the 880N impact force at 0.7MPa smoothly.
Pneumatic Press Tonnage Stop
Set a precise 40mm lower limit for a light assembly press. The 128kgf max force at 1.0MPa is sufficient for seating bearings, and the G1/4 port handles the required air volume.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100 with MBLJ40X100-100
To replace this MALJ40X100-100, order the direct replacement MBLJ40X100-100. Confirm the 40mm bore, 100mm stroke, -100 adjust code, G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB allowed). Since this SKU has no -S magnet, it cannot take a sensor; if you need sensing, step up to an MBLJ40X100-100S for CMSG/DMSG/EMSG compatibility. The adjuster is a travel stop, not a lock.
At 100mm stroke, side-load risk is manageable, but always ensure rigid guiding to prevent rod bending, as the bumper cannot absorb lateral forces.
Upgrade checklist
- ✓ Order the MBLJ40X100-100 (same bore/stroke/adjust)
- ✓ Same 0–100 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 MBLJ40X100-100 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100 FAQ
Yes, the MALJ40X100-100 is discontinued. The MBLJ upgrades the body to a riveted rolling-packed design instead of threaded covers.
Because this specific SKU lacks the -S magnet, it cannot accept any position sensor. The -100 adjuster code provides a usable stroke window of 0-100mm but acts only as a travel stop, not a load lock.
