This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-10-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-10-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 MALJ40X150-10-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10-S 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 140 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-10-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10-S
The AirTAC MALJ40X150-10-S is a discontinued 40mm bore, double-acting single-rod mini cylinder with a rear adjustable stroke stopper. The 10mm adjuster screw lets you trim the rear end position, creating a usable stroke window of 140-150mm. It delivers 628N push and 528N pull force at 0.5MPa, and up to 880N push at 0.7MPa. The exact drop-in replacement is the MBLJ40X150-10-S, matching the bore, stroke, force, G1/4 port, and mounting.
This SKU includes a magnet (-S) for position sensing. The original MALJ uses threaded covers and CS1-M/DS1-M switches, while the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. The fixed rubber bumper absorbs end-of-stroke impact, but the adjuster is a travel stop, not a lock. It cannot hold a load without live air pressure, so fit an external lock for safety.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10-S |

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 MBLJ40X150-10-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10-S Is Used
Injection Mold Ejection
Dial in the exact 140-150mm ejection reach for plastic parts to clear the mold without repositioning external stops.
PCB Depaneling Press
Use the 628N push force at 0.5MPa to shear populated boards, relying on the rear stopper to fine-tune the cut depth.
Automotive Assembly Jig
Set precise clamping endpoints on a manual fixture, using the fixed rubber bumper to absorb the 880N impact at 0.7MPa.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10-S with MBLJ40X150-10-S
To replace this MALJ40X150-10-S with the MBLJ40X150-10-S, confirm the 40mm bore, 150mm stroke, 10mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). Remember the -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. If sizing down, the 32mm bore yields 402N push at 0.5MPa; if sizing up, the 40mm is the largest available in this series. At 150mm stroke, rod side-load can cause premature wear, so ensure rigid mounting to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X150-10-S (same bore/stroke/adjust)
- ✓ Same 140–150 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 MBLJ40X150-10-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10-S FAQ
Yes, the MALJ40X150-10-S is discontinued. The exact drop-in replacement is the MBLJ40X150-10-S, which matches the 40mm bore, 150mm stroke, 10mm adjust code, force, and G1/4 port. You only need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable stroke window is 140-150mm, set by trimming the 10mm rear stopper. Force ratings 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, and cannot hold a load without air.
