This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-30 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).
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-30 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 70 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-30.
The AirTAC MALJ40X100-30 is a discontinued 40mm bore, double-acting single-rod mini cylinder with a 100mm stroke and a 30mm rear adjustable stop. It gives a usable end-position window of 70-100mm. The exact drop-in replacement is the MBLJ40X100-30, matching the G1/4 port, M12x1.25 rod thread, and 628N push force at 0.5MPa.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The rear adjuster sets travel but is a stop, not a lock; it will not hold a load without live air. Upgrading to the MBLJ replaces the MALJ's threaded covers with a riveted rolling-packed body for higher structural integrity.

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 MBLJ40X100-30 carries the same ratings.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X100-30 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×100 | Nominal stroke length in mm. |
| -30 | Adjustable amount: trim the end to a 70–100 mm window. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |
Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Dial the 70-100mm window to set precise Z-axis travel for a PCB drilling spindle, using the 628N push force to maintain downward pressure without bottoming out.
Fine-tune the 100mm extension on a pallet nailing head to drive nails flush into hardwood blocks, relying on the fixed rubber bumper to absorb the 880N impact at 0.7MPa.
Adjust the rear stopper to shorten the cap crimping head travel, ensuring the M12x1.25 rod-end mechanism engages plastic caps accurately without crushing the bottle neck.
To replace the MALJ40X100-30, use the MBLJ40X100-30. It matches the 40mm bore, 100mm stroke, 30mm adjust code, G1/4 port, PT threads, and FA/LB mounting (no back cover or SDB). Because this is a no-S SKU, you lose the old CS1-M/DS1-M sensors entirely; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you need sensing. The adjuster is a travel stop, not a lock.
For sizing, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up is unavailable as 40mm is the largest MALJ bore. The fixed rubber bumper absorbs end impact, but it is not an adjustable cushion. With a 100mm stroke, keep side-load minimized to prevent rod bending.
Upgrade checklist
Yes, the MALJ40X100-30 is discontinued. The exact drop-in replacement is the MBLJ40X100-30, which matches the 40mm bore, 100mm stroke, 30mm adjust code, and G1/4 port. The MBLJ upgrades the threaded covers to a riveted rolling-packed body.
The usable adjustable window is 70-100mm (100mm stroke minus the 30mm adjust code). The 40mm bore generates 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.
