This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-20 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 MALJ40X150-20
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 130 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-20.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-20
The AirTAC MALJ40X150-20 is a discontinued double-acting mini cylinder with a 40 mm bore and a 150 mm stroke. Its rear screw stopper lets you trim up to 20 mm, giving a usable end-position window of 130-150 mm. This 40 mm bore outputs 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X150-20, matching the G1/4 port, M12x1.25 rod thread, and force ratings.
This SKU lacks the -S magnet, so it cannot take a position sensor. The 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 is not an adjustable air cushion. Upgrading to the MBLJ replaces the MAL's threaded covers with a riveted rolling-packed body.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-20 Is Used
Thermoforming Press
Dials the exact 130-150 mm closing depth on a plastic sheet former, using the 628 N push force to mould without crushing the material.
PCB Depaneling Router
Fine-tunes the cutting head reach on an electronics depaneling machine, relying on the fixed rubber bumper to absorb the 880 N peak impact at 0.7 MPa.
Wood Door Clamp
Adjusts the final 20 mm clamping reach on an assembly jig, ensuring consistent glue joints across varying frame thicknesses.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-20 with MBLJ40X150-20
To replace this MALJ40X150-20, order the MBLJ40X150-20. Confirm the 40 mm bore, 150 mm stroke, 20 mm adjust code, G1/4 port, PT thread, and Basic/FA/LB mounting. Because this SKU has no -S magnet, it cannot accept a sensor; if you need sensing on the MBLJ, order an -S model and switch from the old CS1-M/DS1-M to CMSG/DMSG/EMSG switches. The adjuster sets reach but is not a lock.
For sizing, step down to a 32 mm bore for 402 N push at 0.5 MPa, or step up if you need more force. At 150 mm stroke, watch rod bending under side loads; keep the load guided.
Upgrade checklist
- ✓ Order the MBLJ40X150-20 (same bore/stroke/adjust)
- ✓ Same 130–150 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 MBLJ40X150-20 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-20 FAQ
Yes, the MALJ40X150-20 is discontinued. The exact drop-in replacement is the MBLJ40X150-20, which matches the 40 mm bore, 150 mm stroke, 20 mm adjust code, and G1/4 port. The MBLJ upgrades the threaded covers to a riveted rolling-packed body.
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 -20 adjust code lets you trim the rear travel by up to 20 mm, creating a usable stroke window of 130-150 mm. The adjuster is a travel stop, not a lock, and cannot hold a load without air.
