This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X400-50, 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 MALJ32X400-50 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 350 to 400 mm. This model is discontinued — the direct replacement is the MBLJ32X400-50.
The AirTAC MALJ32X400-50 is a discontinued double-acting, adjustable-stroke mini cylinder. It features a 32mm bore and a 400mm stroke, with a 50mm rear adjuster that creates a usable travel window of 350-400mm. The direct replacement is the MBLJ32X400-50, matching bore, stroke, force, and port.
This unit uses a fixed rubber bumper, not an adjustable cushion. The rear adjuster acts as a travel stop to set end position, but it cannot hold a load without live air. The MALJ has threaded covers, while the MBLJ upgrade uses a riveted rolling-packed body. 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 does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ32X400-50 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 MBLJ32X400-50 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×400 | Nominal stroke length in mm. |
| -50 | Adjustable amount: trim the end to a 350–400 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.
Ejecting molded parts from a deep press cavity requires the full 400mm reach, while the 50mm adjuster fine-tunes the retracted rest position to clear a robotic picker arm.
Replace the discontinued MALJ32X400-50 with the exact direct replacement MBLJ32X400-50. Confirm the 32mm bore, 400mm stroke, 50mm adjust code, G1/8 port, and PT threads. Mounting is FA or LB only (no back cover or SDB). The adjuster is a travel stop, not a lock. At 400mm stroke, rod side-load risks bending the 12mm rod—ensure strict alignment to prevent binding.
Upgrade checklist
Yes, the MALJ32X400-50 is discontinued. The direct replacement is the MBLJ32X400-50, matching the 32mm bore, 400mm stroke, 50mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design, but force ratings remain identical.
The 400mm stroke with a 50mm adjuster gives a usable end-position window of 350-400mm. The adjuster is a travel stop, not a lock, and this non-magnet SKU cannot accept a sensor.
