This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X50-20, 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 MALJ32 Adjustable Mini Cylinder MALJ32X50-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 30 to 50 mm. This model is discontinued — the direct replacement is the MBLJ32X50-20.
The AirTAC MALJ32X50-20 is a discontinued double-acting mini cylinder with a 20 mm rear stroke adjuster, yielding a usable 30-50 mm end-position window. The direct replacement is the MBLJ32X50-20, matching the 32 mm bore, 50 mm stroke, and G1/8 port.
This SKU lacks a -S magnet, so it cannot accept 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. Unlike the threaded covers on this MALJ, the MBLJ replacement uses a riveted rolling-packed body. Both rely on a fixed rubber bumper, meaning there is no 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 MBLJ32X50-20 carries the same ratings.

| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 MBLJ32X50-20 matches these values.

Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Trims the end position for a notching station on an aluminum extrusion line, adjusting the 20 mm range to hit exact miter cuts without repositioning the cylinder body.
Fine-tunes the flap-folding stroke on a packaging machine, using the fixed rubber bumper to soften the impact at the adjusted end position for reliable carton forming.
To replace this MALJ32X50-20, order the MBLJ32X50-20. Confirm the 32 mm bore, 50 mm stroke, 20 mm adjust code, PT G1/8 port, and FA or LB mounting (no back cover or SDB allowed). Because this SKU has no -S magnet, it cannot take a sensor; if you need sensing on the MBLJ upgrade, you must switch to the CMSG/DMSG/EMSG switch family.
Remember the adjuster is a stop, not a lock; add an external locking device if the assembly must hold position without air pressure.
Upgrade checklist
Yes, the MALJ32X50-20 is discontinued. The direct replacement is the MBLJ32X50-20, which matches the 32 mm bore, 50 mm stroke, 20 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The -20 code means you can trim up to 20 mm at the rear, creating a usable 30-50 mm stroke window. The adjuster is a travel stop, not a lock, and cannot hold a load without live air.
