This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-100-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 MALJ40X150-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 50 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100-S
The AirTAC MALJ40X150-100-S is a discontinued double-acting mini cylinder with a rear travel stopper. It gives a usable extension window of 50-150 mm. The 40 mm bore yields 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X150-100-S.
This -S SKU has a magnet for CS1-M / DS1-M switches, while the MBLJ upgrade uses CMSG / DMSG / EMSG sensors. The MALJ features threaded covers, whereas the MBLJ uses a riveted rolling-packed body. The rear adjuster sets the end position but does not hold the load without live air. It relies on a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X150-100-S |
| Bore size | Ø40 mm |
| Stroke | 150 mm |
| Adjustable window | 50 – 150 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 MBLJ40X150-100-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100-S Is Used
Stamping Press Feed
Dial in the 50-150 mm pusher stroke on a metal stamping line. The 628 N force securely advances sheet stock without needing custom external hard stops.
PCB Router Depth Stop
Control the cutting depth on a PCB depaneling router. The 100 mm adjust window lets operators fine-tune reach for different board thicknesses on the fly.
Pallet Wrapper Tensioner
Regulate the film feed arm position on a packaging wrapper. The fixed rubber bumper absorbs the 880 N impact at 0.7 MPa, protecting the film web.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100-S with MBLJ40X150-100-S
To replace this MALJ40X150-100-S with the MBLJ40X150-100-S, confirm the 40 mm bore, 150 mm stroke, 100 mm adjust code, G1/4 PT port, and M12x1.25 rod thread. Mounting is Basic, FA, or LB only, as there is no back-cover or SDB option. You must also swap your CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches. The adjuster is a travel stop, not a lock.
If sizing your force requirements, stepping down to the 32 mm bore drops thrust to 402 N push at 0.5 MPa. Stepping up is not an option as 40 mm is the largest MALJ bore. At the 150 mm stroke length, be mindful of side-load and rod-bending forces to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X150-100-S (same bore/stroke/adjust)
- ✓ Same 50–150 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 MBLJ40X150-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-100-S FAQ
Yes, the MALJ40X150-100-S is discontinued. The exact drop-in replacement is the MBLJ40X150-100-S, which matches the 40 mm bore, 150 mm stroke, 100 mm adjust code, G1/4 port, and mounting. You will need to upgrade your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG switches.
The 40 mm bore provides 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 100 mm adjuster is a travel stop that lets you trim the usable extension window down to 50 mm. It does not lock the load without live air.
