This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-50, 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 MALJ32X300-50 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 250 to 300 mm. This model is discontinued — the direct replacement is the MBLJ32X300-50.
The AirTAC MALJ32X300-50 is a discontinued 32mm bore, double-acting adjustable-stroke mini cylinder. A rear stopper screw trims up to 50mm of travel, yielding a usable end-position window of 250-300mm. The direct replacement is the MBLJ32X300-50, matching the G1/8 port, M10x1.25 rod thread, and 300mm stroke.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Impact is absorbed by a fixed rubber bumper, not an adjustable air cushion. The original MALJ uses threaded covers and PT port threads; the MBLJ upgrade features a riveted rolling-packed body. If you previously used a -S variant, note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG.

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 MBLJ32X300-50 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 MBLJ32X300-50 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×300 | Nominal stroke length in mm. |
| -50 | Adjustable amount: trim the end to a 250–300 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.
Adjust the rear stopper to 275mm to control material compression depth in a press fixture, preventing over-travel on the 300mm stroke.
Fine-tune the folding arm reach on a packaging line, trimming 20mm off the full extension to accommodate varying box heights without external stops.
To replace the MALJ32X300-50, order the direct replacement MBLJ32X300-50, confirming the 32mm bore, 300mm stroke, 50mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only (no back-cover or SDB codes apply). Since this is a no-S SKU, it cannot hold a sensor. The adjuster is a stop, not a lock; add an external lock for held loads.
With a 300mm stroke, rod-bending and side-load risks are high; guide the load to prevent rod damage.
Upgrade checklist
Yes, the MALJ32X300-50 is discontinued. The direct replacement is the MBLJ32X300-50, matching the 32mm bore, 300mm stroke, 50mm adjust code, G1/8 port, and mounting. The MBLJ uses a riveted rolling-packed body instead of threaded covers.
The usable adjustable window is 250-300mm (trimming up to 50mm at the rear). The adjuster is a travel stop, not a lock.
