This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-20, 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 MALJ32 Adjustable Mini Cylinder MALJ32X300-20 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 280 to 300 mm. This model is discontinued — the direct replacement is the MBLJ32X300-20.
The AirTAC MALJ32X300-20 is a discontinued double-acting double-rod mini cylinder with a 32 mm bore and 300 mm stroke. It features a rear adjuster that trims up to 20 mm, giving a usable end-position window of 280-300 mm. The direct replacement is the MBLJ32X300-20, which matches the bore, stroke, adjust code, G1/8 port, and mounting.
This SKU has no magnet (-S), so it cannot take a position sensor. The MALJ uses threaded covers and a fixed rubber bumper to soften end impact. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure.

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 MBLJ32X300-20 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 MBLJ32X300-20 matches these values.

| 32 | Bore size in mm (20/25/32/40). |
| ×300 | Nominal stroke length in mm. |
| -20 | Adjustable amount: trim the end to a 280–300 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.
Trims the end position 20 mm to tension varying wire lengths without adding external stop collars to the 32 mm body.
Fine-tunes the folding arm reach on packaging lines, using the 346 N pull force to handle varying box heights smoothly.
To replace the MALJ32X300-20, order the exact direct replacement MBLJ32X300-20. Confirm the 32 mm bore, 300 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and FA or LB mounting (there is no back-cover or SDB option). Because this SKU lacks the -S magnet, it cannot accept a sensor; if you need a switch, the MBLJ-S uses the newer CMSG/DMSG/EMSG family instead of the older CS1-M/DS1-M. The MBLJ upgrade also shifts from threaded covers to a riveted rolling-packed body.
At 300 mm stroke, the 12 mm rod is susceptible to bending under side loads—ensure rigid guidance to prevent rod damage. Remember the adjuster is a stop, not a lock; use an external lock for held loads.
Upgrade checklist
Yes, the MALJ32X300-20 is discontinued. The direct replacement is the MBLJ32X300-20, matching the 32 mm bore, 300 mm stroke, 20 mm adjust code, G1/8 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add a magnet.
The 20 mm adjuster is a travel stop that lets you trim the end position, creating a usable 280-300 mm window. It does not hold a load without air and the cylinder uses a fixed rubber bumper, not an adjustable cushion.
