This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X400-40S, 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 MALJ32X400-40-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 360 to 400 mm. This model is discontinued — the direct replacement is the MBLJ32X400-40-S.
The AirTAC MALJ32X400-40-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. It features a 32mm bore, 400mm stroke, and a rear stopper that trims up to 40mm, creating a usable 360-400mm end-position window. The direct replacement is the MBLJ32X400-40-S, matching bore, stroke, force, and G1/8 port.
This -S SKU includes a magnet for CS1-M or DS1-M switches. The adjuster is a travel stop, not a lock, and the fixed rubber bumper softens end impact without providing air cushioning. The original MALJ uses threaded covers, while the MBLJ upgrade features a riveted rolling-packed body. On a 400mm stroke, rod side-load risks guide wear, so external load support is advised.

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 MBLJ32X400-40-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 MBLJ32X400-40-S matches these values.

| 32 | Bore size in mm (20/25/32/40). |
| ×400 | Nominal stroke length in mm. |

| 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.
Fine-tune the 400mm full extension on a parts escapement to release wide electronic component trays, adjusting the stroke window without adding external hard stops.
Apply 346N of pull force at 0.5MPa to tuck long 400mm packaging flaps on a carton erector, using the rear stopper to time the fold precisely.
To replace this MALJ32X400-40-S, install the exact direct replacement MBLJ32X400-40-S. Confirm the 32mm bore, 400mm stroke, 40mm adjust code, PT G1/8 port, M10x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The -S magnet requires changing your CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors on the MBLJ. Remember the rear adjuster sets end position but will not hold a load without live air.
At 400mm stroke, prevent rod bending by ensuring external guide rails carry the load.
Upgrade checklist
Yes, the MALJ32X400-40-S is discontinued. The direct replacement is the MBLJ32X400-40-S, matching the 32mm bore, 400mm stroke, 40mm adjust code, G1/8 port, and 82kgf max force. You must upgrade your CS1-M/DS1-M sensors to CMSG/DMSG/EMSG switches.
The usable stroke window is 360-400mm via the 40mm rear adjuster.
