This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X100-30, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct replacement is the MBLJ40X100-30.
The AirTAC MALJ40X100-30 is a discontinued 40mm bore, double-acting double-rod mini cylinder with a 100mm stroke and a 30mm rear adjustable stop. It gives a usable end-position window of 70-100mm.
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 | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same 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.
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.
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 direct 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 adjuster is a travel stop, not a lock.
