This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-30-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-30-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 MALJ40X100-30-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 70 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-30-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-30-S
The AirTAC MALJ40X100-30-S is a discontinued double-acting single-rod cylinder with a 40mm bore and 100mm stroke. It is discontinued and the exact drop-in replacement is the MBLJ40X100-30-S. The rear stopper lets you trim up to 30mm, creating a usable extension window of 70-100mm. This 40mm bore generates 628N of push force at 0.5MPa and uses a G1/4 port with an M12x1.25 rod-end thread.
The -30 adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact but provides no adjustable cushion. For your upgrade, the MBLJ40X100-30-S replaces the older threaded covers with a riveted rolling-packed body. The -S magnet on this MALJ works with CS1-M / DS1-M switches, whereas the MBLJ replacement requires CMSG / DMSG / EMSG sensors.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-30-S Is Used
PCB Router Depth Stop
Dial the 70-100mm window to set router Z-axis depth without reprogramming the PLC, using the 628N push force to hold the cutting head.
Aluminum Extrusion Press
Fine-tune the 100mm end position to accommodate varying profile thicknesses, preventing frame deformation during clamping.
Woodworking Door Clamp
Adjust the rear stopper by up to 30mm to switch between cabinet door styles quickly, relying on the fixed rubber bumper to absorb the 880N impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-30-S with MBLJ40X100-30-S
To replace this MALJ40X100-30-S with the MBLJ40X100-30-S, confirm the 40mm bore, 100mm stroke, 30mm adjust code, G1/4 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Remember the adjuster is a stop, not a lock. You must also swap your CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches. If sizing either way, step down to the 32mm bore for 402N push at 0.5MPa, or step up to a larger ISO cylinder for more force.
Upgrade checklist
- ✓ Order the MBLJ40X100-30-S (same bore/stroke/adjust)
- ✓ Same 70–100 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 MBLJ40X100-30-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-30-S FAQ
Yes, the MALJ40X100-30-S is discontinued. The exact drop-in replacement is the MBLJ40X100-30-S, matching the 40mm bore, 100mm stroke, 30mm adjust code, G1/4 port, and mounting. You must update your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The usable stroke window is 70-100mm via the 30mm rear stopper. The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The stopper sets position but does not hold load without air.
