This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-10 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 MALJ40X100-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 90 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10
The AirTAC MALJ40X100-10 is a discontinued 40mm bore, double-acting mini cylinder with a 10mm rear adjustable stroke stopper, yielding a usable reach of 90-100mm. It delivers 628N push and 528N pull at 0.5 MPa. The direct drop-in replacement is the MBLJ40X100-10, matching the bore, stroke, adjust code, G1/4 port, and 128 kgf maximum force.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The rear adjuster sets the end position but does not hold the load without live air; use an external lock for holding. Unlike the current MBLJ which uses a riveted rolling-packed body, this legacy MALJ features threaded covers and a fixed rubber bumper to soften end impact.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10 |

| 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 MBLJ40X100-10 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10 Is Used
Injection Mold Ejector
Dial the 90-100mm reach to strike a mold ejector pin precisely without over-traveling, using 628N of push force to clear parts safely.
PCB Edge Guide Stop
Fine-tune the end position on a conveyor edge guide, trimming 10mm at the rear to accommodate varying board widths while retracting smoothly.
Pneumatic Press Anvil
Set a precise 100mm down-stroke on a small pneumatic press, letting the fixed rubber bumper absorb the 880N impact at 0.7 MPa without machine shock.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10 with MBLJ40X100-10
To replace the MALJ40X100-10, order the drop-in MBLJ40X100-10. Confirm the 40mm bore, 100mm stroke, 10mm adjust code, PT G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The adjuster is a travel stop, not a lock. If you need to step down, the 32mm bore gives 402N push at 0.5 MPa; if you need more force, the 40mm is the largest MALJ bore available. The MBLJ upgrade also changes the sensor track from the old CS1-M/DS1-M to CMSG/DMSG/EMSG, though this no-magnet SKU takes no sensor.
Upgrade checklist
- ✓ Order the MBLJ40X100-10 (same bore/stroke/adjust)
- ✓ Same 90–100 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 MBLJ40X100-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10 FAQ
Yes, the MALJ40X100-10 is discontinued. The exact drop-in replacement is the MBLJ40X100-10, which matches the 40mm bore, 100mm stroke, 10mm adjust code, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M.
The 10mm adjuster creates a usable stroke window of 90-100mm. The full force figures are: 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The adjuster is a travel stop, not a lock, and cannot hold a load without air pressure.
