This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-75 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 MALJ40X100-75
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 25 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-75.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75
The AirTAC MALJ40X100-75 is a discontinued 40mm bore, double-acting single-rod cylinder. It provides a usable stroke window of 25-100mm by letting you trim up to 75mm at the rear stopper. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X100-75, matching the bore, stroke, and G1/4 port.
This SKU lacks a magnet and cannot take a position sensor. The rear adjuster sets the end position but is a travel stop, not a lock. It uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body. If you previously used a -S magnet, the MBLJ switches to CMSG/DMSG/EMSG sensors.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X100-75 |
| Bore size | Ø40 mm |
| Stroke | 100 mm |
| Adjustable window | 25 – 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 MBLJ40X100-75 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 MBLJ40X100-75 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 Is Used
Press Die Trimming
Dial the 25-100mm window to set exact stamping depth on progressive press dies, using the 628N push force to form light gauge sheet metal.
PCB Router Z-Axis Stop
Set a hard 25mm minimum reach on a PCB depaneling router to prevent spindle crashes, relying on the fixed rubber bumper to soften end impact.
Pallet Dispenser Gate
Adjust the exact 100mm full extension to time the release of empty pallets in a packaging line without bolting on external physical stops.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 with MBLJ40X100-75
Replace this MALJ40X100-75 directly with the MBLJ40X100-75, confirming the 40mm bore, 100mm stroke, 75mm adjust code, G1/4 port, and PT thread. Mounting is FA or LB only with no back cover or SDB. This SKU has no magnet, so no sensor is used; the MBLJ upgrade moves from CS1-M/DS1-M to CMSG/DMSG/EMSG if you add an -S. The adjuster is a stop, not a lock.
To size either way: stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to the next standard bore gives higher force. The 40mm bore provides 628N push at 0.5MPa and 880N at 0.7MPa, making it ideal for medium-duty tasks.
Upgrade checklist
- ✓ Order the MBLJ40X100-75 (same bore/stroke/adjust)
- ✓ Same 25–100 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 MBLJ40X100-75 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 FAQ
Yes, the MALJ40X100-75 is discontinued. The exact drop-in replacement is the MBLJ40X100-75, matching the 40mm bore, 100mm stroke, 75mm adjust code, and G1/4 port. The MBLJ uses a riveted body instead of threaded covers.
The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and 128kgf max at 1.0MPa. The -75 code means you can trim up to 75mm at the rear, giving a 25-100mm usable window. The adjuster is a travel stop, not a lock, and this no-S SKU cannot take a sensor.
