This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-50, 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 MALJ32 Adjustable Mini Cylinder MALJ32X450-50 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 400 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-50.
The AirTAC MALJ32X450-50 is a discontinued double-acting mini cylinder with a 50 mm rear adjuster, yielding a usable stroke window of 400-450 mm. The direct replacement is the MBLJ32X450-50, matching the 32 mm bore, 450 mm stroke, G1/8 port, and force ratings.
This SKU lacks a magnet (-S), 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. The original MALJ uses threaded covers and fixed rubber bumpers, while the MBLJ upgrade features a riveted rolling-packed body. If you need sensing, the MBLJ uses CMSG/DMSG/EMSG switches.

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 MBLJ32X450-50 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 MBLJ32X450-50 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×450 | Nominal stroke length in mm. |
| -50 | Adjustable amount: trim the end to a 400–450 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.
Pushes finished aluminum castings out of a CNC machining center.
Sweeps large corrugated box flaps on a packaging line. The 50 mm rear stopper fine-tunes the fold depth for varying carton heights, preventing over-travel on the 450 mm extension.
Guides incoming wooden pallets into a strapping machine. The rear stopper absorbs impact by limiting the stroke to 400 mm, protecting the 12 mm rod from snap loads.
To replace this MALJ32X450-50, order the MBLJ32X450-50. Confirm the 32 mm bore, 450 mm stroke, 50 mm adjust code, G1/8 PT port, and FA or LB mounting (no back cover or SDB allowed). This non-magnet SKU cannot take a sensor; if you need position detection, step up to an MBLJ-S model using CMSG/DMSG/EMSG switches.
At 450 mm, the 12 mm rod is highly susceptible to side-load bending; ensure rigid front mounting and true alignment to prevent rod binding.
Upgrade checklist
Yes, the MALJ32X450-50 is discontinued. The direct replacement is the MBLJ32X450-50, matching the 32 mm bore, 450 mm stroke, 50 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa it pushes 563 N, with a maximum 82 kgf at 1.0 MPa. The -50 code means the rear screw trims up to 50 mm of travel, creating a 400-450 mm usable window. This adjuster is a travel stop, not a lock; it cannot hold a load without air pressure.
