This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-40 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 MALJ40X100-40 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 60 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-40.
The AirTAC MALJ40X100-40 is a discontinued double-acting single-rod cylinder with a 40mm bore and 100mm stroke. It is discontinued and the direct drop-in replacement is the MBLJ40X100-40. The -40 adjust code lets you trim up to 40mm at the rear screw, creating a usable 60-100mm end-position window. This 40mm bore generates 628N push and 528N pull at 0.5MPa.
This SKU has no -S magnet, so it cannot take a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Upgrading to the MBLJ40X100-40 changes the sensor family (if added) from CS1-M/DS1-M to CMSG/DMSG/EMSG, and swaps the threaded covers for a riveted rolling-packed body. Impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.

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 MBLJ40X100-40 carries the same ratings.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X100-40 matches these values.

|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×100 | Nominal stroke length in mm. |
| -40 | Adjustable amount: trim the end to a 60–100 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 60-100mm reach to press connector pins into PCBs without retooling the head, using the 628N push force at 0.5MPa to seat components firmly.
Set a precise 80mm end stroke on packaging lines to tuck heavy cardboard flaps, relying on the fixed rubber bumper to absorb the 880N impact at 0.7MPa.
Adjust the jaw closure depth for varying aluminum rivet lengths in aircraft panel assembly, ensuring consistent pressure without bottoming out the rod.
To replace this MALJ40X100-40 with the MBLJ40X100-40, confirm the 40mm bore, 100mm stroke, -40 adjust code, G1/4 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a sensor. If sizing either way, 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 adjuster is a stop, not a lock; add an external lock for held loads.
Upgrade checklist
Yes, the MALJ40X100-40 is discontinued. The exact drop-in replacement is the MBLJ40X100-40, matching the 40mm bore, 100mm stroke, -40 adjust code, and G1/4 port. The MBLJ upgrades the construction to a riveted rolling-packed body from the original threaded covers.
The -40 adjust code allows trimming up to 40mm, creating a usable 60-100mm stroke window. The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum 128kgf at 1.0MPa. The rear screw is a travel stop, not a lock.
