This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-20-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-20-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 MALJ40X100-20-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20-S 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 80 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-20-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20-S
The AirTAC MALJ40X100-20-S is a discontinued double-acting single-rod mini cylinder with a 40mm bore and 100mm stroke. It provides 628N push and 528N pull force at 0.5MPa. The rear stopper trims up to 20mm, giving an exact usable window of 80-100mm. The drop-in replacement is the MBLJ40X100-20-S, matching bore, stroke, force, and G1/4 port.
This -S SKU uses a CS1-M/DS1-M magnet, which upgrades to CMSG/DMSG/EMSG switches on the MBLJ. The MALJ features threaded covers and a fixed rubber bumper, while the MBLJ uses a riveted rolling-packed body. The adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20-S Is Used
Injection Mold Ejection
Dial the 80-100mm reach to strike an ejector pin precisely without repositioning the cylinder body on the mold platen.
PCB Edge Connector Seating
Fine-tune the 20mm travel stop to seat edge connectors accurately, relying on the 628N push force without overdriving the board.
Packaging Flap Folding
Adjust the end position to fold heavy corrugated carton flaps, using the 528N pull force to clear the path for the next box.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20-S with MBLJ40X100-20-S
To replace the MALJ40X100-20-S, order the MBLJ40X100-20-S. Confirm the 40mm bore, 100mm stroke, 20mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG. If you need to step down, the 32mm bore yields 402N push at 0.5MPa; if you need to step up, this 40mm bore is the largest available, delivering 880N at 0.7MPa. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ40X100-20-S (same bore/stroke/adjust)
- ✓ Same 80–100 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 MBLJ40X100-20-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20-S FAQ
Yes, the MALJ40X100-20-S is discontinued. The exact drop-in replacement is the MBLJ40X100-20-S, matching the 40mm bore, 100mm stroke, 20mm adjust code, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
At 0.5MPa it provides 628N push and 528N pull; at 0.7MPa it pushes 880N, with a maximum of 128kgf at 1.0MPa. The 20mm adjuster is a travel stop that lets you set a usable stroke window of 80-100mm. It does not lock the load without air; use an external lock for holding.
