This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-30-S, 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 MALJ32X450-30-S 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 420 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-30-S.
The AirTAC MALJ32X450-30-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. It features a 32 mm bore, a 450 mm stroke, and a 30 mm rear adjuster, providing a usable end-position window of 420-450 mm. The direct replacement is the MBLJ32X450-30-S, matching the bore, stroke, adjust code, and G1/8 port.
This SKU includes a magnet (-S) for position sensing. The older MALJ uses CS1-M or DS1-M switches, while the MBLJ replacement upgrades to CMSG, DMSG, or EMSG sensors. The original MALJ has threaded covers, whereas the MBLJ uses a riveted rolling-packed body. The rear screw is a travel stop that sets the end position; it does not hold a load without live air. End impact is softened 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 MBLJ32X450-30-S carries the same ratings.
| Pressure | Push force | Pull force |

| 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 MBLJ32X450-30-S matches these values.

| 32 | Bore size in mm (20/25/32/40). |
| ×450 | Nominal stroke length in mm. |

Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Dials the 420-450 mm reach on a routing spindle to cut exact panel depths without remounting the cylinder.
Adjusts the end position by 30 mm to fold varying carton depths accurately on a packaging line.
To replace the MALJ32X450-30-S with the MBLJ32X450-30-S, confirm the 32 mm bore, 450 mm stroke, 30 mm adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back cover or SDB option. The -S magnet means you must switch from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. The adjuster is a travel stop, not a lock, so use an external lock for held loads. At 450 mm, the stroke is under the 500 mm max but requires careful rod alignment to prevent side-load bending.
Upgrade checklist
Yes, the MALJ32X450-30-S is discontinued. The direct replacement is the MBLJ32X450-30-S, matching the 32 mm bore, 450 mm stroke, 30 mm adjust code, and G1/8 port. The MBLJ upgrades the threaded covers to a riveted rolling-packed body and changes the magnet sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 30 mm adjuster is a travel stop that lets you shorten the stroke from 450 mm down to 420 mm. It sets the end position but does not hold the load without live air.
