This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-30, 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 MALJ32 Adjustable Mini Cylinder MALJ32X300-30 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 270 to 300 mm. This model is discontinued — the direct replacement is the MBLJ32X300-30.
The AirTAC MALJ32X300-30 is a discontinued double-acting double-rod mini cylinder with a 30 mm rear adjustable stroke stopper, yielding a usable travel window of 270-300 mm. The direct replacement is the MBLJ32X300-30, matching the 32 mm bore, 300 mm stroke, G1/8 port, and 30 mm adjust code.
This SKU lacks the -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. Upgrading to the MBLJ32X300-30 replaces the MALJ threaded covers with a riveted rolling-packed body. If you previously used a magnet on other MALJ units, note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG.

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 MBLJ32X300-30 carries the same ratings.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 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 MBLJ32X300-30 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×300 | Nominal stroke length in mm. |
| -30 | Adjustable amount: trim the end to a 270–300 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.
Trim the rear 30 mm stopper on a packaging line case erector to tuck inner flaps at varying carton depths, preventing over-travel tears while relying on the bumper for soft end contact.
Fine-tune the 300 mm reach of a press ram applying 563 N at 0.7 MPa to seat aluminum extrusion connectors, adjusting the end position without swapping out the entire cylinder body.
To replace this MALJ32X300-30, order the MBLJ32X300-30. Confirm the 32 mm bore, 300 mm stroke, 30 mm adjust code, PT thread, and FA or LB mounting (there is no back cover or SDB option). Because this specific SKU has no -S magnet, it cannot take a sensor. At 300 mm stroke, minimize rod side-load to prevent bending, as the fixed rubber bumper softens impact but cannot absorb lateral forces.
Upgrade checklist
Yes, the MALJ32X300-30 is discontinued. The direct replacement is the MBLJ32X300-30, which matches the 32 mm bore, 300 mm stroke, 30 mm adjust code, and G1/8 port. The MBLJ upgrades the construction to a riveted rolling-packed body and uses CMSG/DMSG/EMSG sensors if you order the magnet version.
The -30 adjust code means you can trim up to 30 mm at the rear, creating a usable stroke window of 270-300 mm. The adjuster is a travel stop, not a lock; it cannot hold a load without live air.
