This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X200-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X200-30 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 MALJ40X200-30
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30 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 170 to 200 mm. This model is discontinued — the drop-in replacement is the MBLJ40X200-30.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30
The AirTAC MALJ40X200-30 is a discontinued 40mm bore, double-acting single-rod cylinder with a 200mm stroke and a 30mm rear adjustable stopper. This yields a usable end-position window of 170-200mm. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X200-30, matching bore, stroke, adjust code, G1/4 port and mounting.
This SKU lacks a -S magnet, so it cannot accept a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but holds no load without live air. The MALJ uses threaded covers and fixed rubber bumpers, while the MBLJ upgrade features a riveted rolling-packed body. Operating pressure is 0.1-1.0MPa.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30 Is Used
PCB Router Z-Axis Dive
Dial the 170-200mm window to set router depth on a PCB depaneling machine, using the 628N push force to drive the spindle accurately without crashing the base.
Carton Flap Folder
Trim the rear 30mm stopper on a packaging line folder to time the 200mm stroke perfectly with varying cardboard box heights, avoiding new external hardware.
Pallet Stripper Push
Use the 528N pull force to retract a stripper plate on a palletizing cell, tuning the end position to release empty pallets smoothly without sensor feedback.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30 with MBLJ40X200-30
To replace this MALJ40X200-30 with the MBLJ40X200-30, confirm the 40mm bore, 200mm stroke, 30mm adjust code, G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). If you need to step down, the 32mm bore offers 402N push at 0.5MPa; stepping up is not possible as 40mm is the largest MALJ bore. Note the adjuster is a stop, not a lock. For 200mm strokes, prevent rod bending by minimizing side loads. This no-S SKU cannot take a sensor; the MBLJ uses CMSG/DMSG/EMSG switches.
Upgrade checklist
- ✓ Order the MBLJ40X200-30 (same bore/stroke/adjust)
- ✓ Same 170–200 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 MBLJ40X200-30 instead of this discontinued model.
