This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X160-50, 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 MALJ40X160-50 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 110 to 160 mm. This model is discontinued — the direct replacement is the MBLJ40X160-50.
The AirTAC MALJ40X160-50 is a discontinued double-acting, double-rod adjustable-stroke cylinder. A rear screw lets you trim up to 50 mm of travel, creating a usable 110-160 mm end-position window. The direct replacement is the MBLJ40X160-50, matching the 40 mm bore, 160 mm stroke, G1/4 port and mounting.
This SKU lacks the -S magnet, so it cannot take a position sensor. The adjuster is a travel stop, not a lock; it will not hold a load without live air. The MALJ uses threaded covers and the older CS1-M/DS1-M sensor family, while the MBLJ upgrade features a riveted rolling-packed body. Both use a fixed rubber bumper, not an adjustable 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 MBLJ40X160-50 carries the same ratings.

| 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 MBLJ40X160-50 matches these values.

| 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 50 mm rear stop to guide delicate PCB panels into an assembly fixture, using the fixed rubber bumper to soften the end-of-stroke impact on the electronics.
Adjust the end position on the fly to fold varying carton sizes on a packaging line, relying on the 528 N pull force to retract the folding arm reliably.
To replace the MALJ40X160-50, order the exact direct replacement MBLJ40X160-50. Confirm the 40 mm bore, 160 mm stroke, 50 mm adjust code, G1/4 port, PT thread and FA/LB mounting (no back cover or SDB). Since this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, specify an MBLJ with the -S suffix to use the newer CMSG/DMSG/EMSG switches. Remember the rear adjuster is a stop, not a lock, so add an external lock for held loads.
Upgrade checklist
Yes, the MALJ40X160-50 is discontinued. The direct replacement is the MBLJ40X160-50, matching the 40 mm bore, 160 mm stroke, 50 mm adjust code, force and G1/4 port. The MBLJ upgrade shifts from threaded covers to a riveted rolling-packed body.
The 50 mm adjust code creates a 110-160 mm usable stroke window. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air.
