This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-40-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-40-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 MALJ40X150-40-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-40-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 110 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-40-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-40-S
The AirTAC MALJ40X150-40-S is a discontinued double-acting single-rod cylinder with a 40 mm bore, 150 mm stroke, and a 40 mm rear travel stopper. This yields a usable end-position window of 110-150 mm. It delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X150-40-S, matching the bore, stroke, G1/4 port, and mounting.
This SKU includes a magnet (-S) for CS1-M / DS1-M switches, whereas the MBLJ upgrade uses CMSG / DMSG / EMSG sensors. The original MALJ features threaded covers and a fixed rubber bumper; the MBLJ shifts to a riveted rolling-packed body. 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.

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 MBLJ40X150-40-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-40-S Is Used
Injection Mold Ejection
Dial the 110-150 mm stroke window to time the exact ejector pin retraction on a 40 mm bore tool, using 628 N of push force to clear molded parts without binding.
Printed Circuit Board Testing
Set a precise 120 mm depth stop for bed-of-nails test probes, preventing over-travel on delicate traces while the fixed rubber bumper softens the impact.
Automated Door Sealing
Adjust the reach on an industrial oven door to compress high-temperature gaskets accurately, relying on the 528 N pull force to retract the rod cleanly.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-40-S with MBLJ40X150-40-S
To replace this MALJ40X150-40-S, specify the MBLJ40X150-40-S. Confirm the 40 mm bore, 150 mm stroke, 40 mm adjust code, G1/4 port, PT thread, and FA or LB mounting (no back cover or SDB). Change your sensor family from CS1-M / DS1-M to CMSG / DMSG / EMSG. The rear adjuster is a stop, not a lock; add an external lock for held loads.
If you need to step down, the 32 mm bore gives 402 N push at 0.5 MPa. If you need more force, 40 mm is the largest MALJ bore available, so you would migrate to an ISO 15552 series for higher capacities. At 150 mm stroke, minimize side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X150-40-S (same bore/stroke/adjust)
- ✓ Same 110–150 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 MBLJ40X150-40-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-40-S FAQ
Yes, the MALJ40X150-40-S is discontinued. The exact drop-in replacement is the MBLJ40X150-40-S, which matches the 40 mm bore, 150 mm stroke, 40 mm adjuster, and G1/4 port. You will need to swap your CS1-M / DS1-M sensors for the CMSG / DMSG / EMSG family used on the MBLJ.
The usable stroke window is 110-150 mm, set by the 40 mm rear adjuster. 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 adjuster is a travel stop, not a lock, and the cylinder uses a fixed rubber bumper rather than an adjustable air cushion.
