This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the drop-in replacement MBLJ40X160-40S, 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 MALJ40X160-40-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-40-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 120 to 160 mm. This model is discontinued — the drop-in replacement is the MBLJ40X160-40-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-40-S
The AirTAC MALJ40X160-40-S is a discontinued 40mm double-acting adjustable-stroke cylinder. It delivers 628 N push and 528 N pull at 0.5 MPa. The rear stopper trims up to 40mm, yielding a usable 120-160mm end-position window. The exact drop-in replacement is the MBLJ40X160-40-S.
This -S SKU uses older CS1-M/DS1-M switches; the MBLJ replacement uses CMSG/DMSG/EMSG sensors. The MALJ has threaded covers, while the MBLJ features a riveted rolling-packed body. It uses a fixed rubber bumper, not an adjustable cushion. The adjuster sets travel but does not hold load without live air.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-40-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-40-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X160-40-S |
| Bore size | Ø40 mm |
| Stroke | 160 mm |
| Adjustable window | 120 – 160 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 MBLJ40X160-40-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-40-S Is Used
PCB Router Z-Axis
Dials the exact 120-160mm plunge depth for a PCB depaneling router, using the 628 N force to cleanly cut borders without stressing the board.
Aluminum Extrusion Cut-off
Trims the saw stroke window on an extrusion chop saw, ensuring the 880 N push at 0.7 MPa severs the profile precisely at the 120mm minimum.
Carton Flap Folder
Fine-tunes the 160mm reach on a packaging line flap-folder, adjusting the stop without adding physical spacers to the 40mm body.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-40-S with MBLJ40X160-40-S
To replace this MALJ40X160-40-S, order the MBLJ40X160-40-S. Confirm the 40mm bore, 160mm stroke, 40mm adjust code, G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The -S magnet changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a travel stop, not a lock.
For sizing, stepping down to the 32mm bore yields 402 N push at 0.5 MPa. Stepping up is unavailable as 40mm is the largest MALJ bore. At 160mm stroke, ensure side-load alignment to prevent rod-bending.
Upgrade checklist
- ✓ Order the MBLJ40X160-40-S (same bore/stroke/adjust)
- ✓ Same 120–160 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 MBLJ40X160-40-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-40-S FAQ
Yes, the MALJ40X160-40-S is discontinued. The exact drop-in replacement is the MBLJ40X160-40-S, which matches the 40mm bore, 160mm stroke, 40mm adjust code, force, and G1/4 port.
It delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The 40mm rear adjuster provides a usable stroke window of 120-160mm. The adjuster is a travel stop only; it does not hold the load without air pressure.
