This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X15-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X15-10 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 MALJ40X15-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X15-10 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 5 to 15 mm. This model is discontinued — the drop-in replacement is the MBLJ40X15-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X15-10
The AirTAC MALJ40X15-10 is a discontinued double-acting mini cylinder with a rear adjustable stroke stopper. It delivers 628 N push and 528 N pull force at 0.5 MPa. The -10 adjust code trims up to 10 mm at the rear, creating a usable 5-15 mm end-position window. The direct drop-in replacement is the MBLJ40X15-10, matching the 40 mm bore, 15 mm stroke, and G1/4 port.
This SKU lacks a magnet (-S), so it cannot take a position sensor. The rear adjuster sets travel but does not hold load without live air. Upgrading to the MBLJ40X15-10 changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG and swaps the threaded covers for a riveted rolling-packed body. Impact is absorbed by a fixed rubber bumper, not an adjustable cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X15-10 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X15-10 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |

| Bore size | Ø40 mm |
| Stroke | 15 mm |
| Adjustable window | 5 – 15 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 MBLJ40X15-10 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 MBLJ40X15-10 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X15-10 Is Used
PCB Edge-Guide Trimming
Dial the 5-15 mm window to nudge circuit boards into a test fixture without repositioning the cylinder block, using the 628 N push force for secure seating.
Connector Insertion Depth-Stop
Prevent over-travel on delicate plastic header pins by setting a 10 mm rear stop, letting the fixed rubber bumper absorb the 528 N pull impact safely.
Small Parts Ejector
Fine-tune the ejection reach on a pick-and-place nozzle nest to 8 mm, avoiding full 15 mm extension to save cycle time while moving parts reliably.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X15-10 with MBLJ40X15-10
To replace the MALJ40X15-10, specify the MBLJ40X15-10 to keep the 40 mm bore, 15 mm stroke, -10 adjust code, G1/4 port, and PT thread. Mounting is FA or LB only; there is no back-cover or SDB option. Because this SKU has no -S magnet, it cannot accept a sensor, but the MBLJ upgrade supports CMSG/DMSG/EMSG switches. Remember the adjuster is a travel stop, not a lock.
For sizing, step down to the 32 mm bore for 402 N push at 0.5 MPa, or step up if unavailable since 40 mm is the largest MALJ bore offering 880 N push at 0.7 MPa.
Upgrade checklist
- ✓ Order the MBLJ40X15-10 (same bore/stroke/adjust)
- ✓ Same 5–15 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 MBLJ40X15-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X15-10 FAQ
Yes, the MALJ40X15-10 is discontinued. The exact drop-in replacement is the MBLJ40X15-10, which matches the 40 mm bore, 15 mm stroke, -10 adjust code, G1/4 port, and mounting. The MBLJ uses a riveted rolling-packed body instead of threaded covers.
It delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a max of 128 kgf at 1.0 MPa. The -10 adjuster trims up to 10 mm, giving a usable 5-15 mm stroke window. Because this SKU lacks the -S magnet, it cannot take a position sensor.
