This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X50-40, 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 MALJ32X50-40 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 10 to 50 mm. This model is discontinued — the direct replacement is the MBLJ32X50-40.
The AirTAC MALJ32X50-40 is a discontinued 32mm bore, double-acting double-rod cylinder with a 50mm stroke and a 40mm rear adjustable stopper. This yields a usable travel window of 10-50mm, letting you dial in the exact end position without external spacers. The direct replacement is the MBLJ32X50-40, which matches the bore, stroke, G1/8 port, and mounting footprint.
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 fixed rubber bumper softens the end impact, but this is not an adjustable air cushion. Note the upgrade path: the legacy MALJ uses threaded covers and CS1-M/DS1-M sensors, while the MBLJ replacement features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.

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 MBLJ32X50-40 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 MBLJ32X50-40 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×50 | Nominal stroke length in mm. |
| -40 | Adjustable amount: trim the end to a 10–50 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.
Fine-tune the notch depth on 20-series profiles by trimming up to 40mm off the 50mm stroke, relying on the fixed rubber bumper to absorb the 563N impact at 0.7MPa.
Adjust the end position to seat delicate Molex pins without bottoming out, using the 346N pull force to retract the probe safely after each insertion cycle.
To replace this MALJ32X50-40 with the MBLJ32X50-40, confirm your 32mm bore, 50mm stroke, 40mm adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Because this SKU has no -S magnet, you cannot mount a sensor on it. If you need sensing on the new unit, specify an MBLJ32X50-40S and use CMSG/DMSG/EMSG switches. Remember the adjuster is a stop, not a lock, so add an external holding valve for suspended loads.
Upgrade checklist
Yes, the MALJ32X50-40 is discontinued. The direct replacement is the MBLJ32X50-40, which matches the 32mm bore, 50mm stroke, 40mm adjust code, and G1/8 port. The MBLJ upgrades the construction to a riveted rolling-packed body from the original threaded covers.
The -40 adjust code lets you trim up to 40mm from the 50mm stroke, creating a 10-50mm usable window. The adjuster is a travel stop, not a lock, and cannot hold a load without air pressure.
