This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X60-20-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X60-20-S 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 MALJ40X60-20-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 40 to 60 mm. This model is discontinued — the drop-in replacement is the MBLJ40X60-20-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20-S
The AirTAC MALJ40X60-20-S is a discontinued 40mm bore adjustable-stroke mini cylinder. It is double-acting with a single rod and a rear travel stopper that lets you trim the end position by up to 20mm, yielding a usable stroke window of 40-60mm. It delivers 628N push and 528N pull force at 0.5MPa. The exact drop-in replacement is the MBLJ40X60-20-S, matching the bore, stroke, adjust code, and G1/4 port.
This SKU includes a -S magnet for position sensing. The legacy MALJ uses CS1-M or DS1-M reed switches, while the MBLJ upgrade uses CMSG, DMSG, or EMSG sensors. The older MALJ body relies on threaded covers, whereas the current MBLJ features a riveted rolling-packed body for higher structural integrity. Both generations use a fixed rubber bumper to soften end-of-travel impact and lack an adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X60-20-S |
| Bore size | Ø40 mm |
| Stroke | 60 mm |
| Adjustable window | 40 – 60 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 MBLJ40X60-20-S 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 MBLJ40X60-20-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20-S Is Used
Printed Circuit Board Tester
Dial in a 45mm probe travel window to contact PCB test points precisely without crushing the substrate, leveraging the 628N push force at 0.5MPa.
Plastic Injection Mold Breaker
Fine-tune the rear stopper to 50mm to knock injection-molded parts off the tool face consistently, avoiding the need to swap physical spacers for each mold run.
Aluminum Extrusion Press
Set the end position to 40mm for a light squaring operation on soft aluminum profiles, using the fixed rubber bumper to absorb the 528N pull impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20-S with MBLJ40X60-20-S
To replace the MALJ40X60-20-S, order the MBLJ40X60-20-S. Confirm the 40mm bore, 60mm stroke, 20mm adjust code, PT G1/4 port, M12x1.25 rod thread, and FA or LB mounting (no back cover or SDB is used). Remember the rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure. If you need to hold a load mechanically, add an external locking device.
When sizing, you can step down to the 32mm bore for 402N push at 0.5MPa, or step up to the larger 50mm bore class for higher force. Because this is the largest MALJ bore (40mm), 32mm is your only standard downward neighbor. For any stroke approaching 300mm or more, support the rod to prevent bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ40X60-20-S (same bore/stroke/adjust)
- ✓ Same 40–60 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 MBLJ40X60-20-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20-S FAQ
Yes, the MALJ40X60-20-S is discontinued. The exact drop-in replacement is the MBLJ40X60-20-S, which matches the 40mm bore, 60mm stroke, 20mm adjust code, and G1/4 port. You will need to upgrade your position sensors, as the legacy CS1-M/DS1-M switches are replaced by CMSG/DMSG/EMSG sensors on the MBLJ.
The 20mm adjuster lets you trim the rear travel stop, creating a usable stroke window of 40-60mm. The full force figures are: 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The adjuster is a travel stop, not a lock.
